This coachwhip caused a scream, a screeching stop, and a marathon run. But it was worth it.At scream volume “ ---S T O P!!!!!!!!!! ---.“ Yep, Jake had managed to scare me again. I was in the passing lane doing about 65, about halfway past a slower car, when Jake yelled. Fortunately there was no one following tightly so I slammed on the brakes and before I stopped Jake was out of the car running east while we were heading west. I parked on the verge, clambered out and back about 50 yards Jake was stationed in the grass trying to decide what the snake he had seen and I had missed on the side of the road was going to do.
Hurry screamed Jake. Hmppphhh. Not likely. My days of hurrying are long gone. But I WAS closer now. Go out on the road and try to prevent it from crossing. It’s a coachwhip—a PINK coachwhip!
Now I understood. We had seen but failed to catch or even photo pink coachwhips on our last 3 trips to or through Texas. Suddenly I felt Jake’s excitement. I do love racers and racer relatives.
So I limped out in the road and rather than watching me the big snake was now watching me. Then it turned it’s head towards Jake and started to move. In an instant Jake was airborne.In anotjhert instant he was flat on his belly in the grass and sandspurs. And in a 3rd instant he was screaming OWWWWWCH! GET IT! Certainly no problem now because he alresdyu had the snake at midbody and the snake had him by the eyebrow. Interesting dilemma. I wondered which would win?
But heck I wanted to photo the snake as badly as Jake did, so I grabbed it before it decided to swallow Jake and the snake immediately transferred its attention to my arm. Oh well. It was worth it.
Right Jake?
And I guess it might have been because another 5 miles down the road we had a similar but a bit less bitey encounter with a second pink coachwhip.
I was so impressed with these snakes that I did something that I haven’t done in a long while. I decided that if Jake didn’t wish to retain the snake I would like to keep them. Jake didn’t, I did.
But here’s what I didn’t expect. Once home and caged these 2 adult coachwhips proved dog tame. The first time I fed them both slowly left the hidebox, came to cage top, and gently took each thawed mouse from my fingers. No biting, no striking. And both have continued to do so on each feeding attempt. Now I’m excitedly awaiting their next shed. They should be knockouts.

This quietly resting canyon treefrog probably hunkered down for the day.
Although the canyon treefrog, Hyla arenicolor, is common to abundant in many areas, its habit of hunkering down and resting quietly on streamside boulders and rock faces, in rock fissures, concealed in talus, or in crevices in concrete bridges where its pallid coloration renders it almost totally camouflaged, assures that this anuran is usually overlooked.
Having a disjunct range this 2” long treefrog occurs in the Davis and Chisos Mountains of TX as well as much of NM, AZ, and UT, then locally in southwest NV and CO. Its occurence is restricted to areas where at least a small amount of water is permanently available.
As are most treefrogs, this species is capable of remarkable and rapid color and pattern changes. By night it assumes a ground color of rather dark buff, gray, or olive, and is often patterned with extensive darker lichenate markings or well separated, dark-edged, rounded or oval dark markings. The darker markings may be little more than smudges or be well defined, and may be brown, green, or of an intermediate color. Markings may be best defined and ground color the darkest when the frog is chorusing on rainy nights. The lightest colors are assumed when the frog is resting quietly in the morning sun. At such a time the ground color is most apt to be an off-white, palest olive, or very light pinkish-tan, and the dark markings barely discernible. The dorsal skin is rough. A dark-bordered light spot is nearly always discernible beneath the eye. The concealed surfaces of the hind legs are orangeish. The vocal sac is rounded. Males have a dark throat skin; that of the females is light.
When small, tadpoles are quite dark in overall coloration, but with growth lighten considerably and may even appear nearly gold just prior to metamorphosis. The tailfin is usually conspicuously spotted, at least dorsally.
The call, a repetitious stacatto of hollow-sounding notes, is heard most often immediately prior to, during, or closely following rains.

This is an adult male granite spiny lizard.Light phase adult male Sceloporus orcutti are arguably the most beautiful of our spiny lizards. The ground color of adult males may vary from copper to charcoal. A dark wedge, often obscured in darker males, is present on each shoulder. Dorsally, scales are marked with black, turquoise, and yellow-green. The entire venter and throat is brilliant blue. Light phase males often have a broad stripe of intense purple for the entire length of the dorsum. Females tend more towards a coppery ground color, are often prominently banded, and have the purple dorsal area less well defined. The venter is whitish or faintly washed with blue. Juveniles are prominently crossbanded.
Adult males attain a total length of 10 1/2" (svl 4 1/2"). Females are somewhat smaller.
This beautiful rock and cliff dweller ranges southward from the northern side of San Gorgonio Pass, Riverside County, CA, southward to the latitude of La Paz, Baja California Sur. (south of this it is represented by the genetically dissimilar but lookalike Hunsaker’s spiny lizard). Adult male granite spiny lizards attain a total length of 10 1/2" (svl 4 1/2"). Females are somewhat smaller and are less colorful.
One large female laid 11 parchment-shelled eggs in late June. Incubation lasted for 57 days at a variable (room) temperature. The hatchlings consumed small crickets within a day of hatching. Both nighttime cooling and natural photoperiod are probably necessary to induce breeding and the production of viable eggs.
Fast and wary, S. orcutti is most easily approached early in the morning and just before retiring to their crevices for the night.

Whether spots or stripes the red markings are usually at least partially edged with black.Our eastern newts are members of the genus Notophthalmus. Those seen in the pet trade are the four subspecies of the red-spotted newt, N. viridescens. Of these, two subspecies, the red-spotted and the broken-striped newts are, respectively, attractively adorned with a row of black edged vermillion spots or intermittent stripes along both sides of their dorsa. The remaining two subspecies, the pleasantly colored central, and the particularly drab peninsula newts usually lack most, or all, traces of red.
The eastern newts are rather small creatures. The largest race, the red-spotted form, tops out at a mere 5 1/2" in total length. All four subspecies of the eastern newt have quite complex life cycles. Eggs are deposited in water, and hatch into prominently gilled larvae. After a period of time, if conditions are right, the larvae resorb their gills and transform into rough-skinned, often brightly colored, terrestrial dwelling subadults. At this stage of their lives, the creatures are often referred to as "efts." In the northeast, central, and some areas of the south, red or red-orange are the common colors of the efts. Efts in the deep south are often only little, if any, brighter than the adults. This stage exists, conditions allowing, for from one to several years. After completing the eft stage (which is foregone entirely in some newt populations or if terrestrial conditions are unfavorable) eastern newts return to the water, fade in coloration from red to olive-green (with black spotted yellow bellies) and, there, complete their lives.
Adult eastern newts are often sold as "oddities" for aquaria. Slow moving, they are compatible with most "community tank" fish, but will prey upon fish eggs or freshly dead baby livebearers. Adult washed brine shrimp, blood and whiteworms, and chopped earthworms are relished by newts. Some prepared fishfoods are also consumed. Their skin secretions usually protect newts from the occasional aggressive tankmates.

The 3 subspecies of the black swamp snake are so similar that it will take scale counts to differentiate them. This is a Carolina swamp snake.Three races of red-bellied swamp snakes, Seminatrix pygaea ssp., occur in the southeastern United States. They differ principally in the number of belly scales that each possesses. None are restricted to swamps, but, rather, may inhabit all but rapidly moving waters. They are especially partial to those waters that are choked with vegetation. The dense vegetational mats formed by the crowns and root systems of the beautiful and prolific, introduced water hyacinth are particularly favored. In fact (the difficulty I had in finding swamp snakes not withstanding), the spread of the troublesome water hyacinth through southeastern waterways has probably greatly benefitted swamp snake populations.
Seminatrix pygaea is an ovoviviparous species. From three to 14 young, diminutive replicas of the adults in appearance, are birthed in the late summer or early autumn.
Swamp snakes are generally thought of as difficult captives. In nature they are rather specialized denizens of a habitat that is difficult for herpetoculturists to reproduce. If kept captive in either an aquarium or with moist sphagnum as a substrate, a potentially fatal blister disease often manifests itself. If kept on a dry substrate, these snakes often experience shedding difficulties. A happy medium may take considerable effort.
The commonly listed dietary preferences of the species are also not those usually available to hobbyists. Mentioned food items include, among other things, leeches, dwarf sirens, tadpoles, and other such aquatic fare.
However, I have recently learned of one, long-term captive swamp snake that has contentedly dwelt in a small, dry, terrarium (with a water bowl), AND which feeds ravenously on newly born pink mice. Too little is known about the species as a captive for me to hypothesize whether this specimen is the exception or the norm. It might be of interest for other southeastern reptile enthusiasts to experiment with the captive care of swamp snakes, but to be ready to release their specimens back into natural habitats should they not respond quickly and satisfactorily.
Certainly the snake is sufficiently beautiful to warrant the interest of many hobbyists who have space for only a small specimen or two. Although swamp snakes may rarely attain a length of 18 inches, most are adult at from 10 to 14 inches in overall length.
