Another turtle and tortiose pond idea I tried out was to use the large concrete mixing tubs available at home improvement stores. Suggested by long time kingsnake.com contributor Bonnie Keller, this option was one she had used one with the edges cut down at an angle to provide a slope down to a deep end.
At $14 a tub, I wanted to try one straight up because modifying 96 of them would be tough. And I was already looking beyond plastic ponds as likely the ultimate solution.
A rectangular tub that holds just over 20 gallons, it was smaller than the kiddie pools, but still so deep that it required more excavation time than I wanted to expend. I again excavated with a shovel and water hose to seat the tub properly, and again used the auger to great a sump area for drainage, and added a drain plug to the tub.
Though the ends of the tub had a gentler slope than the kiddie pools sides, it was still too steep for the turtles to get a footing to exit the tub. Again I added rocks to provide them entry and exit, but the Eastern Box Turtles had the same problems getting in and out. They would flop about, frustrated, fighting to get out until they found purchase on the rock pile.
Again this proved to be a "workable" solution that on a small scale could be usable once the issues were overcome, but scaling it to 96 pens would be problematic. This pond too, while still in use today, will be replaced by what turned out to be the eventual best solution.
Watch for part 4!

Which amphibian is so slender and attenuate that it looks like a hefty nightcrawler, has two tiny eyes, four legs that are so short and slender that they are easily overlooked, and only one toe on each foot?
If you guessed that it is an amphiuma, you were right on target.
It is the third and least known of the amphiuma species, a foot long nocturnal caudatan, the one-toed amphiuma, Amphiuma pholeter, that lives out its life in deep beds of soupy mud of slurry-like consistency. Although it was described in 1964, it has been only for the last two decades that this taxon has become known to many.
Many of its habitats are on posted private land or in state parks that require permits carry on a search. Found in Florida's Big Bend counties, the Florida panhandle, extreme southwestern Georgia, southern Alabama, and southeastern Mississippi, the one-toed amphiuma is a Gulf Coast specialty and one that I am always happy to see.

The obvious solution for my turtle and tortoise pond dilemma was simple: hard plastic kiddie pools. They've been used uncountable times for this and similar situations, and for most people, they're the preferred option.
While they have some immediately obvious, and a few less obvious, problems, I still ended up trying this pond idea in a pen just to see how difficult the issues were to overcome.
Even though it was beyond "pool" weather for the year, I was able to track down some 3-foot round "dog washing pools" at Petco for $10 that were the right size and shape, even if they had a giant bone imprinted on the bottom. I probably seemed a little odd buying 12 of them, but they were almost out for the year and I wanted to be prepared if this was the best choice for all the ponds. If not, they would still be useful as temporary turtle and tortoise pens.
The first, and most obvious issue, is that kiddie pools have steep plastic sides made of hard plastic that would be difficult if not impossible for a box turtle to climb out of on its own. One suggested fix was to use rocks piled up in the pool to provide entrances and exits, and in the end this is what I did.
While finding enough of the right sized rocks for one pond was easy, it took no time at all to determine that I would be buying a truck full of rocks if I had to do this in 96 ponds. And while replacing the rocks with concrete was a solution, again I saw myself having to buy a truckload of concrete, as well as 96 kiddie pools at $10 each, and 96 drain plugs.
The second major issue was that it took four times as long to excavate all the dirt required to seat the pond in the ground, as it was substantially deeper and larger than the first pond. I did this with a shovel and a water hose. Again I used the auger to create a 3-4 gallon sump in the excavation, but as the pool holds 20 gallons of water or more, it takes a while to drain out.
Once in place the Gulf Coast Box Turtles used it, but the steep sides made it difficult for them to enter and exit. Often they had to splash around, frustrated, until they gained footing on the rocks. While I am still testing the kiddie pool as turtle pond, it is likely to get replaced over the winter. While this is a "workable" solution for one or two ponds, it doesn't scale well to my needs.
In part 3, I'll try another solution!

It was several decades ago, when most of Florida's caves were open to human intrusion, that I first met Florida's little blind salamander.
A friend took me to cave (that I then thought huge) in Calhoun County. It was by far the biggest cave I had ever been in, and soon after entering I was not at all sure that I really wanted to be there. But I had been told that it was a prime locale for the little Georgia blind salamander, Haideotriton wallacei, a ghostly pale neotenic species that I badly wanted to see.
After I entered I stood contemplating the all surround darkness and probably would have continued standing had not one of my companions (they were all spelunkers familiar with the cave) called from far ahead "Dick, there's one here. In fact, there's two. I'm going to turn my light out so I don't spook them."
I chose an area that looked like it would be easy to walk along and moved as quickly as possible towards the disembodied voice. Fortunately there were no forks or hidden chambers and soon I could see Ed standing quietly awaiting my arrival.
And I got to see the little plethodontid.
Today, although these salamanders have now been found in many additional underground sites, the closures of many locales to human intrusion has made it more difficult for field herpers and hobbyists to see them.
I'm glad that I had several opportunities.

Box turtles, though primarily terrestrial, love to splash around in the water, and of course box turtles need access to fresh drinking water, too.
Tortoises need access to fresh water as well, so it's a natural that some type of pond should be included in an outdoor enclosure, even if only deep enough to provide a ready source of fresh drinking water.
I wanted ponds that were deep enough for the turtles and tortoises to immerse themselves, but not big enough to require major maintenance or financial outlay. They needed to be very basic and easily reproduced. They had to be sloped enough to allow the turtles and tortoises easy and safe access, and they had to be easy to clean. I wanted ponds that could be flushed weekly rather than requiring filters that would have to be powered in some manner.
In looking for the right solution, I tried a number of options used successfully by other people. All of them had and have issues.
My initial design had a small rectangular pond excavated from each pen, framed in wood, and concreted in with a sump and drain plug.
For my first test pen, I used this design. I used a shovel to excavate most of the pond, and the auger to create a deep 3-4 gallon sump at the lowest spot. I used some hard plastic from an underbed box lid, and cut a rough cover for the sump hole.
In the center of the plastic, I inserted a 1-5/8 PVC pipe to provide a drain, and placed the plastic with the pipe over the sump hole. With the sump hole covered carefully first so the plastic didn't cave in under the weight, it took around two 60-lb bags of quik-crete to fill my pond excavation, which when cured held approximately 3 gallons of water.
While this worked well and was relatively inexpensive, it seemed more labor-intensive than I'd like. By framing it, the dirt had to be excavated further than planned and required more concrete to build back the slopes.
However, the 3-toed box turtles loved it, and within 24 hours were happily splashing around. The pond allowed them easy access in and out, and was just deep enough to submerge. The biggest issue was that I failed to give the pond a "lip" that would prevent heavy rains from washing down into the pond, so it needs to be flushed if rainwater fills it with mud.
With the first pond down I wanted to try some other ideas. Stay tuned for part 2!

It was time to add the hoophouse roof, but as planned, the final greenhouse would be considerably larger than this first prototype.
That's why I only wanted a temporary solution, until I could determine the size of the final greenhouse, and could plan accordingly. Thus I wanted to try to use the 16-foot steel livestock panels as a temporary solution, and didn't want to permanently affix them to the structure.
Allowing the remaining posts concrete to set overnight, I then placed the steel livestock panel arches into the pens, allowing the bottom of one end to dig into the dirt while I pushed from the other side.
As the other end stopped upon encountering the wall, it began to bow upwards, forming the arch needed for the roof. Once the end I was pushing was also inside the pen, I set it down, allowing the spring effect to push it outward and dig into the dirt as well.
Were this the plan for the permanent solution for the roof, and had this been as big as I was planning it would have been, I would have framed the bottom with 2x4s and cemented the livestock panels in as well. As it was, only their weight, and the pressure exerted by their spring tension from being bent, held them in place, which was enough for a temporary solution.
Once I had the livestock panels in place, I covered the whole thing with poultry wire and then zip-tied some inexpensive tarps across the top to provide temporary shade.
And we were ready for turtles. Not finished, but ready enough to move them from their temporary home.
This worked really well, was quick to build out, used a minimal of materials at hand or easily available, and could be finished as-is with doors, or expanded to be part of a larger entity. Since I had purchased the auger, I had long ago decided to make this part of a larger entity. But, would my design expand in real life as well as it did on the computer? I was about to find out -- and so will you, in the next in this series!

If I were only going to do a single pen, I could have stopped with where I was in my last post, and do the finish out. All that was left was to set the steel panel hoophouse roof up, cover it in wire, and throw a tarp over it. But not yet.
We had planned on three pens for our initial test, so digging another four holes with the auger, I quickly expanded to three pens, using the same approach as for the first pen, one pen at a time. Then I added the posts, the 2x4 toppers on the edges, then the corrugated panels.
The only difference was I needed to snip out a small amount of corrugated steel with tin snips on each of the interior wall panels, to allow the 2x4 top frame to seat properly on the 4x4 posts. Building the two remaining pens took about the same amount of time as building the first pen.
Once all three pens were up, all the walls were checked where they met the ground to ensure that there were no gaps that could provide an escape path. Once that was done, fill dirt excavated from the post holes was used to build up the dirt around the edges of the pens to a depth of 3-5 inches. This would prevent immediate escapes. but would do little to dissuade a burrower from either direction.
When we were done with the basic pens. it was time to consider our herp greenhouse roof. Stay tuned!

I sat in the yard this morning watching the ducks swim in their little pool and the dogs play rambunctiously over the expanse of the yard. It was a sunny 75 degrees Fahrenheit and very comfortable overall. Then came the blue jays. Within moments there were 8 or 10 of them, all screaming at the top of their lungs.
Then came an American crow, and then another. Cawing and gurgling they joined the screaming jays. At first I thought this to be an owl response, but even with binoculars I could see neither an owl nor a hawk. But then I noticed the birds seemed to be looking down and finally, in a leafy limb-end bower, I made out a sinuosity of form - a snake. It was small, probably only 3 feet long or perhaps even a bit smaller.
As I watched, it began moving downward and it was apparent that it was a yellow rat. The snake's movement prompted the jays to find a new upper level of volume to their cacophonous calls. The snake didn't seem to care. I stood and moved towards the tree and the crows, more nervous than the jays, departed.
The snake continued downward until less than 20 feet separated us. The jays, with a final look of disdain, flew away. The rat snake got to the lowest limb, moved in towards the trunk and the last I saw it was coiling slowly, largely secluded between the trunk and an immense grape vine that clambered up the tree.
I walked away thinking this was a lucky snake. Perhaps it was because I was so close that the frenzied calls of the jays and crows hadn't summoned a red-shouldered hawk. Had one of these herp-eating buteos arrived the ending for this tale and the snake would probably have been just that: a literal ending.

Dragging some old 4x4 fenceposts for the first pen I used a saw to cut them down to four 40-inch lengths.
Using our recently purchased auger, I dug out four holes spaced 8 feet apart as four corners of my square pen. Dug down approximately 18 inches, we wanted our posts to stick up 22 inches.
Even with the auger, digging into the hard, dry, baked, clay soil was difficult. Every time I tried to dig, the auger bit would bounce off the big chucks it would gouge until they finally choked the bit to stoppage. A simple solution turned out to be pouring a bucket of water into a started hole and letting the dirt soak it up. With the clay thus loosened, the auger had no trouble boring holes in the dirt quickly and as designed,
Once the holes were dug, the 4x4 posts were set into them, dry, and then topped by 2x4s on three sides, one side at a time, the "open" side being left for expansion to the other two pens. With the pens' frame in place on one corner, a cordless drill with a drill bit and another with a Phillips bit were used to mount the corrugated steel walls of the pen.
With all four walls mounted in a simliar fashion and leveled as best possible, the 4x4 posts for the first pen were then set in the ground with approximately a bag and a half of quik-crete per hole. Once set, the first basic pen was complete and we were ready to add the remaining pens. While this was a lot of work it only took a couple hours of labor.
More to come!

Using a simple computer graphics program and a clean canvas, I began to rough out a design for a "small" greenhouse solution, a single pen 8 foot by 8 foot square, covered by steel livestock panels arched over to form the hoophouse roof.
The walls of the pen would be 8 foot x 2 foot corrugated steel roof panels secured to 4 inch x 4 inch posts set in concrete and rising 22 inches out of the ground, topped by 2x4x8s around the outside. As designed, it used both existing materials on hand and new materials that needed to be sourced and priced. And it proved to be relatively easy to duplicate and expand the number of pens as needed. Simply copying the single pen design image and pasting it next to the original allowed me to easily expand the design and figure the budget accordingly.
But while everything looks good on the computer, real life has a tendency to interfere. So we had to prove the design.
After a quick trip to the store for some corrugated steel panels, concrete, and importantly a gas powered auger, we set about our mission, building a permanent 3-pen herp greenhouse that could be inexpensively and readily expanded.
Placement of the greenhouse was the first decision. It needed to be on ground that was relatively flat, yet have a slight grade, on good soil, and positioned so that it was expandable to a considerable size. The perfect place turned out to be right next to my power pole, which was convenient to my house and driveway. Laying out my materials in a rough approximation of where they were to be placed, I was ready to start.

The distribution of the Escambia map turtle, Graptemys ernsti, long thought to be a variant of the Alabama map turtle, is restricted to parts of the Choctawhatchee, Escambia, Yellow, and Shoal rivers and tributaries in western Florida and adjoining Alabama.
The Escambia map turtle is quite similar in appearance and habits to the more easterly Barbour's map turtle and the more westerly Alabama map turtles.
As with other map turtles, there is marked sexual dimorphism in this species. Females attain an adult carapace length of 9 to 11 inches and males are less than half that size. Like several other map turtle species, females develop an immense head and the diet of the adult shifts from the insects of the juveniles to the snails, clams, and mussels of the adult. Males eat insects throughout their lives.
At 14 to 20 years of age the females attain sexual maturity. Males, as noted, smaller and less bulky, may begin breeding when only 3 to 6 years old. Females nest from late spring through midsummer. From 3 to 6 nests are produced, more or less at 3 week intervals and produce an average of four nests containing 5 to 13 eggs.

While our little temporary greenhouse was great for its purpose, it wasn't much of a barrier to large threats, such as a big dog, or heavy winds or weather. It wasn't anchored at all, and could be lifted up and moved with two hands. And in the end it was temporary, just as planned.
To do box turtles, and tortoises, properly, and in the quantities I was planning on, I needed to design something larger, more permanent, and most importantly, expandable, so I could add on as needed.
It didn't require heating or cooling, but did need to be screened to keep the pets in and the threats out. And it needed to have overhead cover during the summer to provide some shade during the oppressive heat of July and August.
It wouldn't need electrical connections, but it would need water for the planned misting system. Most of all, it had to be stable in the weather, and with winds often gusting over 50 mph and higher, it would need to be secured and anchored well. And it had to be designed so a single person could build and install it.
Some things I tried worked well, others not so much. Some design elements didn't scale, and attempting to use existing materials sometimes burdened the design, leading to somewhat catastrophic failures.
Along the way I found better ways to do things, and better materials and tools to use. But first, I needed to start with a single small greenhouse for the first groups of box turtles. Stay tuned for part 2!

"Got one, Patti."
"Good. A copperhead?"
"No. A crayfish."
"Oh."
I didn't know why she sounded so disillusioned. After all, it was wanting to see a crayfish, the firebacked crayfish to be exact, that had drawn us to the Apalachicola National Forest. The copperhead (a southern copperhead, Agkistrodon c. contortrix) was to have been a secondary prize.
But now, with the beautiful crayfish--one of several species, the natural color of which is similar to a well-boiled Maine lobster, found and photographed, it was copperhead time.
Our plan was to follow and check both leaf-strewn, sun-patched, banks of the meandering ravine-stream in hopes of seeing one of these well-camouflaged snakes.
That was our plan. But the copperheads had plans of their own. Their plans, it seemed, contrary to the norm, were to make things as easy as possible for we bumbling humans.
And their plan superseded ours. Barely 2 steps out of the stream we found the first copperhead stretched across one of the few open patches. And although we only needed one for photos, about 10 steps farther, lying quietly in a tight coil, was a second copperhead. Success.
Our next stop would be on the Chipola River in hopes of finding a map turtle. But that's another story.

In many places, herpers who have the space may have the opportunity to raise their pets in an outdoor enclosure.
Some reptiles just don't thrive inside, and with others, their size or captive requirements my require it. Outdoor enclosures can be as simple or as complex as you want to build them, and many herp owners turn to greenhouse designs as a starting point.
Whether you buy a greenhouse kit or build one from stuff just laying around, as long as the greenhouse is secure and escape-proof, it can be used to raise everything from turtles and tortoises to chameleons and iguanas.
The simple hoophouse greenhouse pictured here was built by one person (me) in about four hours, using scraps from other projects and a total of 16 screws. Designed for temporary use for box turtles, it used some old fence boards and several welded wire livestock panels bent over to provide the hoop frame.
It was wrapped in rolled welded wire and covered with tarps. It could be wrapped in plastic just as easily, but for our purposes the welded wire did the job.
With rocks bordering the walls to prevent dig-unders, this enclosure was used for several weeks while a more permanent home was being built. While the materials you have at hand may vary, a trip to the home improvement store can replace any missing items, and in a nice afternoon you can end up with something functional. And with a little more effort, and more materials, something this simple can be easily expanded into a more permanent structure.
Me, I'm going to need something more permanent. And larger. Much larger.

Florida has two species of naturally occurring map turtles, both riverine species. Both are wary. Very wary.
Since they are possessed of excellent eyesight, a hopeful observer is more apt to see only the ripples left behind a plunging map turtle than a view of the turtle itself. One of these species is the beautiful, dimorphic, Barbour's map, Graptemys barbouri. These map turtles are inhabitants of Florida's Apalachicola, Chipola, and Choctawatchee, Alabama's Pea and Flint, and Georgia's Chattahoochee and Flint river systems. In Georgia, the ranges of the Barbour's and the Escambia map turtles abut or overlap, and hybridization is known.
But, if you're both cautious and lucky, you may actually see one of these brownish gray, saw-backed, map turtles basking quietly on a protruding snag. Sometimes you'll catch them perched well above the water level on what would seem to be an impossibly thin branch. The broad, well developed, head markings vary from creamy-yellow to lime green and cover most of the temporal area.
Females of this species are adult at ten to twelve inches in length and probably first breed when they are between twelve and twenty years of age. Adult females develop enlarged heads and feed primarily on snails, clams, and mussels, both native and introduced. Males, narrow-headed, are adult at four to five inches in length, breed at four to six years of age, and like the juveniles feed largely on insects.
Barbour's maps are protected or of regulated take throughout their tri-state range.

Pierson, Kenny, and I had been out on Florida's western panhandle searching for brook, dusky, and dwarf salamanders. We had done okay and were now working our way back eastward stopping here and there to roll logs and dip our nets in whatever water was available.
We spent a lot of time sorting through aquatic vegetation, finding the tadpoles of various frogs, a few siren and amphiuma, a glossy crayfish snake or two, and in one net-full of vegetation, a neonate cottonmouth.
The finding of a cottonmouth in Florida is seldom worthy of comment for, although many snake species are somewhat harder to find than they once were, cottonmouths remain abundant.
When neonates, most are quite brilliantly colored in oranges, tans, and browns. But this baby, an intergrade between the eastern cottonmouth, Agkistrodon p. piscivorous, and the Florida subspecies, A. p. conanti, was clad in oranges that at some places bordered on red, bright tans, and deep browns, and was much prettier than most neonate cottonmouths.
In fact, I have not yet seen another that equals it.

Although I had encountered Couch's spadefoots, Scaphiopus couchii, pretty much throughout their range in the United States, I had never happened across a breeding congress such as I was then listening to in southern Sonora, Mexico.
Created by the seasonal rains (known as "monsoons"), a newly flooded playa stretched ahead of us in the darkness as far as the beams of our flashlights could penetrate. Spadefoots in the hundreds, probably actually in the low thousands, sat at the edges, floated in the shallows, and continued to access the still enlarging puddle from all sides.
Fortunately it was late and only an occasional vehicle traveled the busy road next to which we were parked. Most of the frogs and toads that attempted to cross made the trip safely.
The incessant bleats of the Couch's spadefoots dominated the chorus, but the quacks, trills, peeps, and burps of other anuran taxa were impossible to ignore.
Couch's spadefoots are little (two to two and a half inch) yellowish "toads" that often have overtones of army green or brown. Like other spadefoots, they have a single heel spade. But in the case of the Couch's spadefoot, the spade tends to be elongated and sickle-shaped rather the the "teardrop" shape of other species.
Unlike the true toads, all spadefoots have vertically elliptical pupils, a definite giveaway.

By sundown the towering cumulus were clouding the southwestern sky. Only a few minutes later the clouds were nearer, thunder was rumbling incessantly and bolts of lightning were spearing the heavens. We started eastward then decided to leave the pavement and drive along a sandy desert road. Good choice. A big boa, Boa constrictor ssp., had started to cross.
Although small for a boa (5 to 7 feet) and of dark coloration, this heavy-bodied snake was among our target species on this trip.
Brad and I were in southern Sonora, Mexico. The last time I had been there, about 4 years earlier, this northwestern Mexican state was in the midst of a several year drought and herp movement had been at a minimum. At that time, after seeing only a few leopard frogs and spiny-tailed iguanas, I quickly headed straight back to the border and spent a few days in Arizona before heading home.
But this time, not only was there promise of rain, there was ample evidence that the seasonal monsoons had arrived in the form of dampened earth, replete roadside ponds, chorusing anurans and the boa then on the road before us.
That evening it had poured for well over an hour and the herp activity was spectacular. Before returning to our motel we had seen and photographed more than 20 species. Among these were 4 boas of fair size.
What a difference the rains made.

It had been another 109 degree day in Texas's Big Bend. Not only had the day been hot, but a couple of hours after sundown the heat of the day was still palpable. As it approached 11:00PM, the thermometer was still registering 99 degrees Fahrenheit. But at least at 50 miles per hour we had a breeze on these mountain roads.
On this, our last night in the Big Bend region, we were varying our tactics. We'd drive a while, then check a couple of roadcuts, then drive some more. By midnight the temperature had plummeted - to 97 degrees Fahrenheit. Pocket mice and kangaroo rats skittered and hopped across the roadway. My search for a Texas lyre snake continued, but showed little promise of fulfillment. I worked one side of a roadcut. Jake worked the other. I found a female black widow with egg cases, Jake found a...
Well, I didn't know exactly what Jake found until well after the fact. In a kidding manner, Jake had mentioned finding an iconic gray-banded kingsnake, Lampropeltis alterna, at the end of the cut but I hadn't seen it. Although he continued to kid, I somehow failed to take him seriously - and he still hadn't shown me the snake!
He did flash his light at me a few times, just before I returned empty-handed to the car. I thought he just wanted to be picked up. So that's what I did. I picked him up and we made another run out the road and back. It was still a roasting night and even at 2:30AM the only snakes we saw were a few western diamondbacks and a single juvenile Mohave.
The next day during the long drive home we compared notes and Jake made a comment or two about gray-banded kingsnakes. The comments went right over my head. In only a matter of hours we were unloading Jake at his house and he was grinning all the while like a Cheshire Cat!
At the end he made some comment like, "Whoops. I forgot that bag in back of my seat. Could you get it and check it for me?" I could and did. Gray-banded kingsnake. A big one. A beauty of the gray banded phase. I was the last to know. Hoodwinked! Jake was laughing so hard at my amazement that he could hardly stand.
Our trip had been even better than I had known.

Successful though our trip to the Big Bend region of West Texas had been, Jake still didn't have an opportunity to hunt roadcuts for the fabled gray-banded kingsnake. Of course, since this was Jake's first trip to the "Bend" he was interested in photographing nearly anything he could and would see, be it a black widow or a crevice lizard.
But I was being a bit more selective. Having, over the years, found more than my share of gray-bands, I was primarily interested in finding a Texas lyre snake, a dweller of the rocky deserts and roadcuts that eluded me for the more than 60 years I sought it.
Guess what? It eluded me again just as the gray-band had so far eluded Jake. In fact, I was beginning to wonder whether we should be road-hunting rather than walking the cuts. Were we just wasting our time by walking? So far all we had seen was heavy traffic. But my outlook quickly changed when Jake, suddenly brought up short in mid-stride, stated "Milksnake" and asked "What kind is out here?"
My mind stopped working when I heard milksnake. I knew that the subspecies would be the beautiful New Mexico milk, Lampropeltis triangulum celaenops, a snake I had found elsewhere in its range but never in the Big Bend.
As I turned and hustled towards Jake I saw him bend and pick up a wriggling candycane, one of the prettiest New Mexican milks I have yet seen. I just couldn't imagine this subspecies getting much brighter than the example Jake was holding. When you check out the 3 accompanying pictures, I think you'll agree.
Our walk had suddenly taken on a far more favorable aspect.

The fat shiner swam the 6' length of the 125 gallon aquarium in less than a second. It disappeared from this earth about 5 seconds later.
First I was watching it and thinking how gracefully it sped through and around the waterlogged snags. And even knowing the fish's purpose in the tank, I was unprepared for the speed and dexterity of that strike by the nearest tentacled snake, Erpeton tentaculatum.
The strike wasn't unexpected. I had been keeping and breeding tentacled snakes for several years. In fact, the only difference was that I had more than doubled the size of the shiners proffered. What had been unexpected was the speed - mere seconds were involved - with which the snake caught and swallowed the prey.
For those of you not familiar with the tentacled snake, it is a fully aquatic homolopsine species that occurs widely over Southeast Asia. It attains a length of two to two and a half feet and inhabits quiet, often silted waters. The genus contains only a single species with two distinctly different patterns, a blotched and a striped.
It is a live-bearing species. The "tentacles" (actually two short rostral projections), are sensory and seemingly assist the snake in locating their piscine prey in waters having limited visibility.

"Stop!"
Seems like Jake hollers "stop" a lot when we're on the road. I haven't figured out whether that's because I'm always looking in the wrong places or because of my failing vision. Probably a little of both.
"That was a 'horny toad.' A baby horny toad!" Jake continued.
I was already backing up and sure enough, barely on the pavement, at grass edge, was a juvenile Texas horned lizard, Phrynosoma cornutum. And just behind it was another.
The stretch of road we were on was a bit north from the Rio Grande in western Texas. Over the years, I consistently found adult Texas horned lizards along this roadway. Although this strong and consistent population indicated that I was seeing a viable and reproducing population, until this trip I had not actually seen any juvenile examples.
But now, with two tiny post-hatchlings on the roadside there was no longer any question of whether or not the population was breeding.
Thanks, Jake.

The world's a pretty hostile place for herps these days, with a number of emerging pathogens threatening the existence of many species of reptiles and potentially all amphibians. Here are four of the worst threats:
1. The big daddy of them all, which some scientists say might wipe out pretty much every amphibian on earth: chytridiomycosis. It's caused by Batrachochytrium dendrobatidis. While protocols exist to cure it in the laboratory, the only positive news for animals in the wild is some amphibians may be able to mount an immune response to the fungus. Maybe.
2. Snakes worldwide, mostly in the boid family, have been struck by Inclusion Body Disease, thought to be caused by a retrovirus. The disease is fatal in symptomatic animals, and there's ongoing research into it at the University of Florida.
3. A deadly virus recently diagnosed in box turtles in Southwest Florida and affecting amphibians worldwide: ranavirus.
4. A nasty fungus killing snakes in the Midwestern and Eastern U.S.: Ophidiomyces ophiodiicola. The good news: There's a new test for the disease. The bad news: So far, there's no cure, and the fungus seems to outwit all current disinfectants. At great risk is the last eastern massasauga rattlesnake population in Illinois.

"Stop!" Jake hollered. There's a turtle on that rock. It's a slider! Oh and there's a couple of others swimming around the rocks."
We were on a curve on a narrow section of road on a bluff overlooking the Rio Grande. The road shoulder was only a couple of feet wide and even though traffic was light, I was nervous about stopping. I slowed, eased forward, and just as I was about to suggest that Jake hop out with his camera and I would find a parking spot and walk back, the shoulder widened slightly and I was able to stop safely.
Both Jake and I were happy about this opportunity, for earlier, as we had begun to focus on a distant slider at another pull-off, the turtle had dropped from its basking snag into the silted water and was gone.
These, on the other hand, rather than having already basked and warmed were just hauling out of the river to begin a new basking sequence. Hopefully, this would provide us a second opportunity for photos. And it did.
Adults of the Big Bend slider, Trachemys gaigeae, are rather small, attaining a length of only 6 to 8 inches. This taxon has 2 discrete red spots behind each eye and an extensive dark figure on the plastron.
Its range in the USA is discontinuous in the Rio Grande (and some tributaries and nearby waterholes) from the Big Bend of Texas to central New Mexico.
Since this is a long ways from our homes we were happy to be afforded the photo ops offered by the cooperative turtles. We may try to upgrade next year, but for now consider these pictures more than adequate.

Two subspecies of bark anoles, Anolis distichus, once were identifiable in south Florida. These were the brown to gray Florida bark anole, A. d. floridana, and the green bark anole, A. d. dominicensis.
Wherever and whenever the two came together, they readily interbred until the characteristics of the bark anoles in Florida were so muddled that in most cases the subspecies were no longer readily identifiable. The resulting intergrades were (and are) most like the Florida subspecies with an occasional individual being a pasty greenish-gray.
Then in August 2014, a friend posted some pictures of bark anoles he recently found and his comments regarding their color changing abilities were of interest. He said that most in this small population were on mossy barked trees and although typically dark colored, when feeding on the small ants of which their diet largely consists, a few temporarily assumed a decided green coloration.
I asked for and received 2 males that he collected when they were at their greenest (these were returned and released back into the colony), but in the week that I had them - skewed by capture and captivity - this is what I learned:
More than 99% of the time the lizards were dark brown. In fact, as far as I know, one never assumed green of any shade. But on one night, and only on that night, while sleeping, one of the bark anoles did assume a green color.
At dusk that night it was dark brown.
At midnight it was still dark brown.
At 2:00AM it was light brown.
At 2:30AM it was bright green.
At 2:38AM, after I took a couple of pictures, disturbing the lizard only with the flash, it was again a very dark brown.
To the best of my knowledge it never again, while captive, assumed the green color.
If the color is this fleeting in the wild, it is no wonder we don't see many green colored bark anoles in south Florida.
I hate the picture in a cage, but it's a lot better than having no record at all. Now it's time to head for Miami and try for photos of the lizards in situ.

Longtime reptile keeper and breeder and kingsnake.com member Rico Walder, known for his passion for green tree pythons, lost his long fight with brain cancer yesterday.
Rico always brought out the best in people, and watching the reptile world pull together, with dozens of fundraisers at reptile events coast to coast over a multi-year period, showed just how special he was to our community. His fight was our fight as well, and to lose him makes the reptile world seem a colder, emptier place for all.
Rest in peace Rico. You are already missed.

Ohhhhhh, OK. You can call it the Rio Grande if you choose.
In fact, that is usually what I call this heavily silted river which is the border between Texas and several Mexican states. Jake and I were observing the river in the Big Bend region of West Texas. What caught our attention was a sizable, distant, emergent snag on which 2 turtle species, a soft-shell and a slider, were quietly basking in the August sunshine.
Air temperature, already 100 degrees Fahrenheit, would rise another several degrees before the setting of Sol would allow temperatures to first stabilize and then begin a slow--a very, very slow--drop. This was, after all, the Chihuahuan Desert.
There was a wide spot in the river and the snag on which the turtles rested was far enough away to tax the maximums of our cameras and lenses. There seemed no way to get closer. Jake was particularly concerned for both species were "lifers" for him.
Despite the distance, the slider dropped into the river and was immediately lost to sight as we positioned ourselves. That was frustrating. But the soft-shell, the Texas subspecies of the spiny soft-shell, Apalone spinifera emoryi, seemed to make itself more comfortable. It sat quietly, moving only its head and neck, as we snapped photo after photo. Out of the many snapshots several proved usable. It was a well spent half hour.
Now to find the slider again.

Jake and I have just returned from 10 days in the Big Bend region of West Texas. This was Jake's first sojourn to the area and my first return in about 20 years. We had a great time and are already plotting next year's visit. We talked in some detail about locales and targets (both herps and birds) and had a fair idea of what we hoped to find.
Jake's list was simple. He wanted to see and photograph at least one of everything. We didn't even come close! My list of half a dozen herp and 2 bird species was a bit more specific. It was topped with the Chihuahuan lyre snake, Trimorphodon vilkinsonii, (on this we failed) and ended with a colorful male of the Southwestern earless lizard, Cophosaurus texanus scitulus, (on this we succeeded).
At a length that occasionally exceeds 7 inches, the Southwestern earless lizard is marginally the largest of the earless clan in the United States. When suitably warmed, it is also the most colorful. During the breeding season, the pinks, greens, blues and black of the dominant males must be seen to be truly appreciated.
Should you be traveling in southeastern Arizona, southern New Mexico, or western Texas, be sure to look them up. And have your camera ready. You'll certainly want a photo.

It was more than 10 years ago that I found my first Everglades Burmese python, Python molurus bivitattus. A little over 7 feet in length, the snake was crawling slowly across the roadway and rather than trying to escape when we neared, it simply coiled slightly and stopped crawling. At no time did it display the slightest hostile behavior.
About a year and a half later, I found a second example. Like the first, although larger, this one showed no hostility causing me to ask myself "what is with these pythons?"
Another 2 years passed and I found a third python, a 5 footer, that was a little feisty - but only a little.
In August of 2011, I found a fresh DOR hatchling, still well within the Everglades, but outside the boundaries of the National Park.
And then in 2014, a friend and I found a 10 footer: an underweight male that was far more interested in avoiding us than in confrontation.
5 pythons in over ten years found during more than 25 Everglades sojourns that had pythons as at least one of the target species. That's not very many. Admittedly these were only road sightings and well over 1,500 of the big snakes have been documented, removed, and euthanized.
I didn't hike through choice python habitat, which according to experts is nearly anyplace you chose to hike. As most recent trips drew to a close without the sighting of even one python, I couldn't help but think of the great and much lauded FWC sponsored python hunt of 2013. This fiasco, dubbed a success by the "experts," turned up only 68 pythons which was the cumulative result achieved by almost 1,600 hunters over a period of nearly a month.
Over the last 10 years, I have seen several Burmese pythons in Florida's Everglades. Except for a single DOR hatchling, those I have seen were between 5 and 12 feet in length. Whether you call this unfortunate or fortunate, it is a fact. Although there is no question that pythons should not exist in Florida, since they are here due stupidity or accident I am glad that I have had the opportunity to make their acquaintance.

Whether you know it by the American name of rhinoceros viper or the name of river jack that is commonly heard elsewhere, Bitis nascicornis is a magnificent snake that deserves the utmost respect.
It is easily determined whence came the American name, for this stocky viper has several pairs of moderately to greatly elongated scales on its nose. Although it can swim, the name of river jack seems a bit inaccurate. Rather than being actually a riverine species, the snake is known to be an inhabitant of the forests and rarely of the woodlands of West and Central Africa.
Those in some populations are among the world's most beautiful snakes while others are dull (especially the old adults) and of muddy appearance. Those from the northeastern parts of the Democratic Republic of the Congo (often referred to as the Ituri Forest or Ituri Rainforest) are often very brightly colored. This snake has a dangerously potent venom that is primarily haemotoxic but that also contains neurotoxins.
A live-bearing species, female rhino vipers may have from 10 to 36 babies. Normal adult length for this very heavy bodied viper is 25 to 36 inches with the females attaining a larger size than the males.
Despite its lethal potential this snake, popular with hobbyists, remains occasionally available at rather affordable prices.
