Many years ago, I decided (to my own satisfaction) that although most caiman are hatched feisty, the 2 species of the so called dwarf caimans of the genus Paleosuchus are hatched actually evil.
We see the smooth-fronted species, Paleosuchus trigonotus, on almost all of our trips to the Peruvian Amazon and no experiences I've had with them has altered my opinion in the least. In fact, if anything, my interactions involving this caiman, be they hatchlings or adults, have cemented my opinions ever more firmly.
The scales of this brown-eyed caiman are heavily ossified, providing an alternate name of armored caiman. Comparatively small though they may be, these 4 to 6 foot long alligator relatives are strong, have very sharp teeth, immensely strong jaws, are perpetually ready to do battle, and our guides and I have learned to afford them much respect.
A couple of years ago, a few early arriving clients (experienced herpers, all) got together on a rainy night before my arrival and decided to roadhunt the road to Nauta. After all, isn't that what herpers do? Somewhere along the way they encountered a 30 inch long smooth-fronted caiman, just sitting on the wet pavement minding its own business.
They stopped to look at it. It looked like, with minimal repositioning it would make a fine photo. One of the group attempted to reposition the little beast with a stick only a few inches long. Now this would have been fine for a spotted salamander, but for a 30 inch smooth-front?
Nope. It didn't work. Didn't even come close to working. And the result? Another herper learned respect for "little-but-feisty" beastie. I just wish I had been there to watch the action.
It's always good to start a trip with a little entertainment.

Last month I visited Kerala, a south Indian state, with my friend and rescuing partner Axy (Akshay Parhalkar) and our teacher Mr. Iqbal Shaikh (a legend of Indian herpetology and holder of the title “snake man of India” during the 1970s) in search of King Cobra. We weren't lucky enough to find one, but still had some great experiences.
It was the last day of our trip so we decided on a riverside jungle herping adventure. For the first two hours we were not able to find anything. Tired and exhausted, Axy and I decided to have a quick bath in the river. I still remember the lines said by Sir, "Don’t go too far, as I have a strong feeling that we’ll get something at the river bank only."
Keeping that in mind, we were swimming close to the riverbank and suddenly we heard some villagers shouting, "Snake snake." Hearing that word, Axy and I ran and jumped between the huge river rocks towards the direction of the crowd. After reaching the spot we realized that both of us forgot to wear our clothes and we were just wearing our boxers/underwear, but we didn’t let it bother us and continued with our task.
It was a fat and healthy 8-foot Indian rat snake trying to hide under a rock, so I pulled it out gently. It didn’t take much time for the snake to turn into an aggressive creature, so we decided to do a head catch. It was a strong snake so it was a bit difficult for head catch and Axy got bitten while doing the head catch. After making the snake calm we got dressed and clicked some photographs.
The most embarrassing and funny part of this incident was that we were watched and clicked by more than 20 villagers during the task when both of us were "almost naked." This incident still makes us laugh and it adds an unforgettable experience to my life.

There's no question that the pattern and colors of this snake are an effective - a very effective - camouflage.
In more than 20 years of tromping through the Peruvian rainforest, we have seen only two speckled forest pitvipers, Bothriopsis taeniatus, and so well did they blend with the background foliage that we almost missed seeing both of them.
Actually, I consider that low number very surprising. The only snake that we search assiduously for and have found fewer of is the emerald tree boa. Of that taxon we have found only one, and unlike the pitviper that one example was not on our normally utilized preserves.
This pitviper may have a ground color of tan or gray to forest or olive green. The pattern is complex and variable, consisting of flecks, blotches, and bands of darker browns, grays, and greens to a green much brighter than the ground color. This pitviper is a slender snake. Adults are often three to three and a half feet in length, but some may attain a length of a few inches over five feet. This snake may spend as much time on the ground as in the trees.
It is a live-bearing snake that reportedly has a small number of young. The neonates are more precisely marked than the adults.

The kukri snake, Oligodon arnesis, isn't very familar to snake lovers from the African and American continents. If you're among them, you probably wonder where he got his name.
These snakes are called "kukri" because their teeth/fangs look like a Nepali weapon called the kukri.
Despite their weaponized name, these snakes are non-venomous. They are found in many Asian countries including China, Thailand, and Malaysia.
India is home to 12-13 species of kukri snakes amongst which the banded kukri is the most common -- and probably why it's also called the common kukri snake.
The body of the banded kukri is round with a short tail, and the body color is ash-or reddish-brown with black or brown bands. The underside is white and usually three black ‘V’ shapes are present on the head.
These beautiful snakes are found in ant hills, crevices in rocks, tree hollows, old houses, or heaps of stones. It’s a shy-natured snake and generally they don’t bite, but there's no guarantee as I have been a victim of their painful bite. They feed on reptile eggs, geckos, skinks, and mice. These snakes constrict their prey with 2-3 coils before swallowing it. Size varies from 40-70cms in adults. They are oviparous by nature, laying 5-7 eggs in crevices.
It’s always a joyful experience during the rescue of these snakes as they are usually quiet and I love them, even though I still carry some fear because of that one bad experience.

India has 17 species of pit viper, mostly found on trees. The hump-nosed pit viper ( Hypnale hypnale) is an exception.
Hump-nosed pit vipers are found in Goa and some parts of Karnataka, India. Like other pit vipers these snakes have hemotoxic venom, but mildly so. These snakes are not fatal to humans as they are very rarely found on rescues and they mostly spend their entire lives in forests.
Hump-nosed pit vipers are nocturnal by nature but sometimes are seen coiled on rocks near streams, low bushes, or under fallen leaves on the ground during day. The head of this snake is pointed and triangular with a tip curved upwards, giving it its lance-headed apperance.
The body color is grey or brown with dark brown bands and yellowish or reddish tail tip. What I like best about the young hump-nosed pit vipers is the way they wriggle their tails to attract lizards, skinks, and geckos.
The maximum size of hump-nosed pit vipers is 55 cm. These beautiful snakes are viviparous by nature and give birth to 4-10 young ones.
It was really an unforgettable experience encountering this beauty in the jungles of Goa while herping at 2 AM. I was so amazed to see this snake that I didn't leave the place for 1-2 hours. I just sat on a rock and observed the snake until it disappeared in the dried leaves.

Everywhere and nowhere best describe where you may find this tropical American lance-headed snake. Certainly the fer-de-lance, Bothrops atrox, is one of the commonly seen venomous taxa on the Project Amazonas Biological Stations and in nearby villages, as well on trails far distant from all activity. Many seen are neonates or juveniles but some are 4 foot long adults.
Depending on weather patterns, this snake may be seen in some numbers on one day and night and then be absent, or at least not seen, for several days.
Such was the case on one rainy trip. Small puddles along busy trails on Madre Selva Biological Preserve had drawn sizable populations of breeding frogs and the presence of the frogs had, in turn, drawn the fer-de-lances. Day or night for two days following the storm, we could check the perimeters of the puddles and find 3 or 4 of these snakes, often with body distended by a belly full of frog. However, by the third night we found that they had mostly dispersed and by the following day we saw none.
Then there was the time when a fer-de-lance wasn't present when we left the tambo (2-person cabin) to walk to the kitchen, but one was coiled tightly between the stepping stones when we returned a half hour later.
On another occasion, we hadn't seen a fer-de-lanc in the week we had been at the station. But one evening one person (who later told me he hadn't believed all of my warnings), was distracted in conversation with his son and almost stepped on one that was crawling slowly across the camp clearing.
We were sure glad it was "almost."
As I say, these brown on olive-brown snakes are everywhere, and nowhere. If you're in Amazonas use care - always. Plan ahead when out at night. Carry a flashlight and use it.

Although eastern glass lizards, Ophisaurus ventralis, live in our yard, finding them on demand is a definite problem. I have never been able to do so yet! When it comes right down to it, whether I'm looking for them in my yard or elsewhere, I seldom succeed - at least on the first try.
There are 4 species of glass lizard (family Anguidae) in the United States. Three of the four, the mimic, the island, and the eastern, are restricted to the Southeastern United States. The fourth, the slender glass lizard, has two subspecies. The eastern subspecies is found from Kentucky and Virginia to Louisiana and Florida. The western subspecies ranges from a disjunct population in Wisconsin to Nebraska (barely) and southward to south Texas and west Louisiana.
Glass lizards are accomplished burrowers. In addition to making their own burrows when substrate is of the proper consistency, they may enter and follow a burrow pre-made by a small rodent or large insect. They also often seek seclusion beneath surface debris.
I have been fortunate enough to have found four eastern glass lizards in our yard, three beneath sheets of tin or plywood and one found about 12 inches below the ground surface while I planted a tree. The island and the mimic glass lizards seem a bit less urbanized and are most often encountered in open sandy woodlands or meadows.
Despite being seldom seen, of the four American taxa in this genus of oviparous lizards, only the mimic glass lizard is considered uncommon.

"Pit viper" a very familiar name to all snake lovers across the world. India is home to 17 species of pit viper; I'm sure this is the largest snake family in the country. One can find pit vipers in all parts of India.
The bamboo pit viper, Trimeresurus gramineus, is the most commonly found pit viper in India. Studies say tree pit vipers are hemotoxic by nature, but their venom is mild compared to the vipers on the land. I guess this might be the reason for excluding pit vipers from the "Indian big four" venomous snakes. There is no proper evidence of any deaths caused by pit viper bite in India, and even I have not come across a case during my research.
The bamboo pit viper is moss-green, yellowish-green, or bright green, with a faint or distinct brown or black pattern on its back. This pattern is darker in juveniles. The head is triangular, flat, and broad, and the eyes have vertical pupils.
Pit-like sensory organs are present between each eye and nostril. Lip scales are yellowish, and the underside is pearl white or yellowish.
Pit vipers are found in hilly forests. They are slow moving, and it vibrates its tail when disturbed and may strike with mouth wide open.
Bamboo pit vipers feed on small mammals, mice, young birds, frogs, and lizards. The maximum length is 3.5 to 4ft. They are viviparous by nature and give birth to 5-15 young ones. A captive female in Maharashtra had given birth to 21 young ones.
As I have mentioned a couple of times in my articles, it's very difficult to find tree snakes in my area as it's a concrete jungle, so I never rescued a bamboo pit viper. But because they are somewhat easily found on herpings, I have come across these snakes many times, and these are one of my favourites -- as I've said before, "I love the shade of green."
I would thank my friend Riyaz Khoja for allowing me to share these beautiful photographs.

The Günther's racer, Coluber gracilis , (non-venomous), is one of the species of racer snakes found in India.
It is named after the great German-born British zoologist, ichthyologist, and herpetologist Albert Günther.
Racer snakes are known for their speed and quickness; the Günther's racer is also known for his beautiful appearance, with large eyes having round pupils, and grayish-brown body with narrow, black-edged yellow bands.
These bands are darker toward the head and lighter toward the tail. The head can be distinctively identified with a black-edged yellow inverted ‘V’ mark. The underside is white.
An average size of Günther's racer that I’ve been familiar with was 30-50cms long. This beautiful, fast snake lives under dried leaves or stones and feeds on geckos and skinks. It is viviparous by nature and lays 4-7 eggs during May and June.
I've only had the opportunity to rescue these beautiful snakes three times. When I got the call about Günther's racer, it was from someone I knew telling me a tiny snake entered her office. She even sent me its picture online, but before I had a look at the picture I was planning to transfer the call to another rescuer because the place was around 20 miles away. However, the picture was very helpful for me to recognize it was a Günther's racer.
I decided to rescue this tiny creature myself, as it is very rare to find one. It was a very delightful rescue, as it was an average sized Günther's racer which helped me a lot in my research as well.

As a herping youngster in New England, I eventually found several eastern milk snakes. On my first trip to the New Jersey Pine Barrens with my mentor, Gordy Johnston, I had seen several Coastal Plains milk snakes Asa Pittman's, an at erstwhile dealer. But a drawing I saw of the southeastern scarlet kingsnake, (then Lampropeltis doliata doliata, now Lampropeltis elapsoides, but for a very long time between these two names it was known as Lampropeltis triangulum elapsoides) ran continually through my young mind.
I finally met a scarlet kingsnake, again with Gordy, but this time in southeastern South Carolina at a place called Okeetee. Our encounter with the scarlet kingsnake might have been on our very first trip to Okeetee. If not then, it was on our second.
At the partially shaded edge of an otherwise sunny field, a long dead pine had toppled. Probably before its impact the bark had loosened in large sheets, and after impact had loosened even more. Bark had broken free in patches and fallen to the ground beneath the trunk. Other patches had merely loosened and were still lying atop or wrapped around the trunk.
Beneath one of these patches, I found the most beautiful snake I had until then seen - a 12 inch long scarlet king!
Since then I have seen dozens more but only this one, and the largest (a 25 inch monster found years later in central Florida), remain so firmly etched in memory.

There are several snake species in Amazonia that undergo extreme color changes as they progress from hatchling/neonate to adulthood.
The orange to green color changes of two, the two species of emerald tree boa, are well known. However, there is a lesser known species, the rusty whipsnake, Chironius scurrulus (a colubrine) about which you seldom hear, that undergoes color changes as great as, but exactly the opposite of, those of the boas.
This slender snake, adult at over six feet in length, is leaf green and largely arboreal as a hatchling. Predominantly terrestrial (actually a largely river-edge, frog eater that swims well and fast) it is rusty brown as an adult. Between these two color extremes the snake appears more faded, a rather nondescript greenish-gray and then grayish-red.
It is a species that we always enjoy finding on our Amazonian Peru tours.
But enough talk. Meet the rusty whipsnake.

Recently India has been facing a lot of weather and climatic changes. Sometimes it's really hot in winter and sometimes it rains in summer. I usually avoid herping during the summers as the climate is very hot and humid, and the forests are dried up to a certain extent.
In my city, it rained many times in March. A group of herpetologist friends and I decided to go herping in some nearby hills. Four of us were all set for herping.
Me and my group of friends have been into rescuing, conservation, and study of snakes for the past five years, and all of them are part of a new generation of Indian reptile hobbyists. So I would like to introduce them: Akshay Parahalkar (Axy), metalhead and a snake rescuer and studying reptiles; Anirudh Rathod, a newcomer who has been doing great work in snake rescuing; Riyaz Khoja, who I mentioned in my previous article, a very good wildlife photographer and snake rescuer who always helps me with his magnificent photographs for my articles.
So coming back to my story, we started herping at 7 AM so we could see some of our reptilian friends basking in the sun. It did not take much time to find one.
Axy and Anirudh were the ones to spot this amazing snake called the common bronzeback tree snake, Dendrelaphis tristis, one of the beautiful tree snakes of India. The common bronzeback is thin and long with flat elongated head and large eyes with round pupils. A brown or bronze stripe runs along top of body from head to tail. The underside is yellowish, bluish-green, or light green.The upper lip scales are light yellow.The size varies from 3.5 ft to 5.5 ft, and is viviparous by nature.
After finding this beauty, Riyaz clicked these beautiful photographs and we continued with our herping.

When I started with my studies on Indian snakes, I was really surprised when I read that India has five species of coral snake. I used to believe these highly beautiful snakes were only found in American countries.
I can find a few in my area, but I have to be lucky enough to get one, and never got a chance to rescue any. Whenever I go herping, I always tell my fellow companions that for a particular period of time they have to search only for coral snakes.
The striped coral snake is very rare to find as compared to other venomous snakes, and very shy by nature. I have never seen an aggressive coral, and to be frank I still don't know how coral snakes attack because I haven’t seen any of them attacking.
That's why, despite being venomous, coral snakes are not included in the “Indian Big Four” as they are not highly harmful as compared to vipers and cobras.
The striped coral snake, Calliophis nigrescens, is thin, very long, and has a cylindrical body with short tail. The body is blackish-blue, bluish-purple, or reddish-brown. There are 3-5 stripes on their body, but they are extremely faint in blue and black individuals.
The head is black with a light streak behind the eyes. The underside is red and the scales under tail are partly white.
Striped coral snakes are found mainly under dried leaves. They curl up their tail as a threat display when they are disturbed. They feed mainly on other snakes and viviparous by nature. These snakes are endemic to certain parts of western hilly areas of India.
I have encountered this snake only twice on my herpings. When I found the striped coral snake ,it was really unbelievable and I forced my companions to pinch me so I could believe I'd really found this beautiful creature.

Four Days Before Christmas, and all through the 'hood,
The rain was torrential, conditions were good.
Jake said, "It's the night. We really should go."
I checked the computer, barometer's low.
So off in the storm, wipers on high,
The rain still fell in sheets from the lowering sky.
Traffic was heavy on roads, wet and black,
But for 50 long miles we stayed right on track.
We turned toward the pond, it had been a long ride,
But the "sallys" were active. We're both glad we tried!
Road herping central Florida style with Jake: December 21, approximately 67 degrees Fahrenheit, and heavy rain.
Species seen: mole salamander, Ambystoma talpoideum; tiger salamander, Ambystoma tigrinum; spring peeper, Pseudacris crucifer. Also seen: southern toad, green treefrog, and southern leopard frog.

As winter fades back into a dormant state until next year, spring means herps are on a journey to find the perfect mate for breeding season in the southeast. This means several things to different species that will all be simultaneously doing the same thing at once: moving.
We were traveling to southwestern Mississippi from Alabama in search of black pine snakes ( Pituophis melanoleucus lodingi) on a late March afternoon, and decided to stop at a rest area to stretch out our legs for a few minutes.
While walking around in this coastal lowland and surrounded by shallow swampy marsh habitat type, we stumbled upon a pair of Gulf Coast box turtles ( Terrapene carolina major) breeding, with the female completely flipped over on her back and the male upright, which apparently is nothing out of the ordinary.
Reaching sexual maturity anywhere between 7-10 years, box turtles breed in the spring and females start seeking out nests June-July to lay a single clutch of 3-8 eggs at a time. It is also more than very likely that the same Gulf Coast box turtle we came across will lay her eggs near the water she was found around, and nest several different times this year with more clutches.
This subspecies of North American box turtles is one of six others that exist, and also un-mistakenly the largest. They are generally described as being matte brown or almost black in coloration with a distinct yellow stripe down their backs, but can also have thin or thick blotches .
It is also noted that if you happen to see one trying to cross the road, please feel obligated to help it do so safely but to also not relocate it so that it doesn't get back into the road trying to go to where it was originally traveling to!

For decades, attempting to ascertain whether this little Jamaican/Cuban gecko, Sphaerodactylus argus, has been extirpated from or remained extant in Florida has been problematic.
The ocellated gecko was first seen on Key West in 1944. It was probably introduced to Florida in produce or construction shipments. But from its first sighting until 2005, it was seen so infrequently that its continued presence here had been questioned by biologists. So infrequent were the sightings - in some cases the hiatus between sightings was nearly 2 decades - that in at least 2 cases it was surmised that the lizard had been extirpated from America's herpetofauna.
But we now know it's here, and there is a fairly robust population.
On Key West in 2005, I collected a half dozen adult ocellated geckos and several eggs that I only knew to be a Sphaerodactylusof some species. When the eggs hatched, I had 2 ashy geckos and several ocellated geckos.
Later in the year, another friend saw a dozen adults and a third person collected a large number for the pet trade. Within the last 2 years many more have been seen. It seems that for the better part of 7 decades this little lizard has been hiding in plain sight.

In a short unreasoned response, USFWS refused an extension request of the effective date (April 9, 2015) of the Lacey Act listing of reticulated pythons, green anacondas, Beni anacondas, and DeSchauensees Anacondas.
USARK had requested an extension of the 30-day period from the date of the Lacey Act listing in the Federal Register.
USFWS specified that it was rejecting the request for breeders and other sellers to try to minimize the economic impact of the listing of these species. USFWS has broad authority to set the effective date or extend the effective date of Lacey Act listings, but argued that an extension would undermine the purpose of the listing. USFWS also argued it did not have time to complete any process necessary to grant such an extension.
In response, USARK has filed for a preliminary injunction and temporary restraining order to obtain the requested extension by an order of the Federal District Court already hearing the USARK case filed to challenge the listing of the Burmese python, yellow anaconda, and Southern and Northern African rock pythons (and amended now to include the reticulated python etc.).
The hearing will be held at 2 PM on Tuesday, April 7. USFWS'opposition will be filed by noon, Monday, April 6. USARK's reply will be filed by noon, Tuesday, April 7.
Although courts are reluctant to grant the extraordinary relief of a TRO and PI, USARK's memorandum makes a very compelling case. The memorandum sets forth in detail why USARK meets the requirements of "likelihood of success on the merits" and "irreparable harm" that will be suffered. In addition, the memorandum explains why USFWS would suffer little or no harm if an extension of the effective date was delayed until a final decision on the merits of the USARK case.

Introduced to the Lower Keys from Cuba, when adult this tiny lizard is rather nondescript ashy gray in color. The color is actually a complex pattern of ash - sometimes in reticulations, sometimes as fine dots--over a ground color of olive-brown.
But when even tinier, as a 1 1/4 inch long hatchling, it is one of the most beautiful lizards in the United States.
Hatchlings have an olive green body that is often suffused with pale orange, a gray-green head, and a fire orange tail. The limbs are pale orange. Head and body bear precise bands of dark pigment. Dark blotches are present on the top anterior 1/3rd of the tail. Pretty? You betcha! The intensity of color and pattern fades with the lizard's growth.
This is a common gecko on the Lower Keys but is most common on Key West and Stock Island. Hiding by day beneath debris or behind bark on both living and dead trees, it emerges at night and may then be seen on the walls of buildings, trunks of trees, or atop debris.

In a surprising move this morning USFWS Director Dan Ashe has announced that the federal government will seek an immediate ban on the importation, interstate transport, and possession, of the Mediterranean House Gecko, Hemidactylus turcicus, an invasive species that has taken over in many states in the Southern U.S.
"Thousands of these geckos have been released over the years by pet owners into the everglades, and climate change will only hasten their spread. Without a multi-billion dollar taxpayer funded effort to eradicate these invaders, millions of American insects will be at risk, including the endangered Alabama blue nosed fly, and the Daytona bar hopper. That said I have instructed the service to add this species to the invasive species list and we shall immediately seek to ban their importation and ownership under the Lacey act statutes" said Director Dan Ashe. "Additionally we have instructed the service to draw up a multi-decade eradication plan that will use techniques used and successfully developed to combat other invasive reptiles such as the Burmese Python and Brown Tree Snake."
USFWS plans are said to include setting up an invasive gecko task force to bring together the many state and federal agencies working to resolve the issue, airdrops of millions of bait insects from helicopters across the U.S., as well as the issuance of powerful flash lights to all field agents over 5 feet in height. Homeowners across the U.S. are being asked to help in this fight, the service requesting that they immediately check the eaves and overhangs of their dwellings at night for the invasive geckos, and reporting any they find to their USFWS regional office. Homeowners found to be harboring geckos after the ban has been implemented face fines up to $250,000 under the current Lacey act statutes.
