 An adult male Saba Isle Anole. Anolis sabanus
Saba!
What is Saba?
Saba, it turns out, is a tiny upthrusting in the northeastern Caribbean. Only about 5 miles across, this tiny island has sandy beaches (expensive hotels), 4 main villages having descriptive names such as The Bottom (Saba's capital), Windwardside, St. John's and Zion's Hill (aka Hell's Gate), and even has some rainforest. Oh yes, it also has 3 indigenous and endemic reptiles, an anole, a Sphaerodactyline gecko and a Colubrine snake.
But initially it was only the anole that I found of interest. I had learned of this lizard through Jake, who had talked of both its homeland and beauty for months. In fact, Jake wanted to fly to this lizard’s dot of land to photograph it. But to me it seemed a long journey simply to photograph a single lizard species, and an anole at that.
Then Jake found an online pic and my attitude was swayed. I had just about made up my mind to opt into the “Jake’s Anole Expedition” when an online ad for that exact species popped up on my computer screen. Rather than take the trip. I bought a couple of the lizards…both gender. The live lizards that arrived were even prettier than the pix I had seen. The anoles are sexually dimorphic, the female lacking the polka-dots of the adult males.
Both the male and the female, seem to be doing well, eating tiny crickets and flightless fruit flies. Males have a beautiful, large, deep yellow throat fan. I hope you’ll agree that, although not one of the larger species, it is a species well worth looking at.

 This adult Inyo Mountain was about 4" in total length.
I think I can move that boulder, Gary said. It’s the only thing I can see that’s blocking access.
I agreed with the 2nd of Gary’s statement, but the initial comment concerned me. It was a BIG boulder and neither Gary nor I were of boulder-moving stature. But move it he did, and we were again on our way along a tooth-loosening Jeep trail—and we were not in a Jeep.
It was an amphibian, a caudatan, that had brought us onto this sun-drenched trail. Around us stretched the peaks of the Inyo Mountains. Soon, no more boulders halting progression, we hoped this trail would swing a bit southward and then as it met with a tiny mountain stream, take us again eastward. And if we were then where we thought we actually should be, the stream would widen a bit, the moist banks would be surrounded by rock flakes, and beneath those flakes an interesting species of slender salamander, the Inyo Mountain Slender Salamander, Batrachoseps campi , was known to dwell.
As hoped for the Inyo Mountain Salamander we found was of the silvery phase. The presence of this salamander in an otherwise sere habitat proved the importance of even tiny trickles.
Guess what? Lady Luck was with us. We were right on target.
In a sudden turn the trail neared the trickle even more closely. The dried grasses gave way to tiny but beautiful orchids. And then the trail ended. We hopped out and carefully made our way to a stand of small shrubs interspersed with an occasional desert palm and sycamore. There the stream widened to a shallow 10 or 12 foot puddle, and along the banks were the rock shards we had hoped for.
As hoped, our careful search (of only a few minutes) turned up a salamander, one only, but this one was of the light phase. Photos were taken, the salamander replaced, and we left. A half hour later were back on the paved road, en route to another herp quest.

A Canebrake Rattlesnake, large and irate, but not without reason.
The sun was well below the horizon. Darkness was being ushered in by the plaintive calls of Chuck-Will’s-Widows and a few Green Treefrogs. The warmth of the day was giving way to what had been forecast to be a cool evening and an even cooler night. One more round on the herping road and time to head home.
But I only made it half-way and decided that enough was enough. I reversed and headed for home, still some hundred dark miles southward. Ahha. Pavement! Progress. MPH? Let’s say 60. A thick cover of clouds added to the darkness.
I swung around a curve and—SNAKE. Big Snake. It was in the opposite lane and was moving steadily towards the edge, the long roadside grasses and almost impenetrable woodland blackberry tangles.
I stood on the brakes, safely reversed direction—and the snake had disappeared. Was it a cottonmouth? I had been able to see it was very heavy-bodied. I clambered out of the car headlamp a blaze, clampstick in hand, and almost at woodland edge saw the tall grasses moving sinuously.
On my first step towards it I got snagged by blackberries, went down, and lost my headlamp that went out when it hit the ground. I floundered around, retrieved the dropped utensils, said the heck with this, stood up and stopped in my tracks. That big snake had decided to ”talk”, not in the hisses of an angry cottonmouth, but, rather, in the whirring language of an irate rattlesnake. And in this area it almost had to be a Canebrake, Crotalus horridus atricaudatus.
From that point on, all went well. I sidled towards the ratcheting, finally saw the coiled and irate snake, got a couple of dozen photos, and left after estimating the length of the snake as well over a hefty length of 4 feet. A bit darker in color than most seen in the area, it was the highlight of the night, and quite probably for the season.

 This almost all white example of the Giant Worm Lizard was found by a Peruvian villager.
Amphisbaenids are rather amazing creatures. In fact, they are so amazing that they are in their own family, the Amphisbaenidae. Most are legless, at least 3 species (in Mexico) have proportionately small, clawed, forelimbs but lack rear limbs. Amphisbaenids (often referred to as “worm lizards”) have for the most part, a, wedge-shaped head of the same width as their bodies that is adapted for digging, a cylindrical body, loose skin, scales arranged in rings, and a short tailt. Some species are long and slender, others, especially the European members of the family, are shorter and proportionately stout.
Despite perpetual but never confirmed tales of a Pacific Coast species, only a single taxon, the 14” long Florida Worm Lizard, Rhineura floridana, is known to occur in the USA. This, as suggested by both its common and species names, may be found in FL and extreme South Central Georgia.
The largest/longest amphisbaenid, is the 2 to 2 ½ foot long Giant Amphisbaenid, Amphisbaenia alba of South America where it ranges southward from Venezuela and Trinidad to Northern Argentina. It is also known as the Red (dorsal and lateral color) or the White-bellied (self-explanatory) Amphisbaenid.
In our dozens of trips to Amazonian Peru we had never seen one of these impressive creatures until one day a villager walked into the compound holding one that had been found near his home. Notable were the already mentioned colors, the darker eyespots, and the fact that while held it was not hesitant to attempt to bite.
Much in print information about this remarkable “worm lizard” is speculative. However, it is known that it is oviparous, laying ~12 eggs. It is also known that this burrower is often found in association with the nests of leaf-cutting ants. Stomach contents have disclosed that this species is primarily insectivorous, but also will eat nestling rodents and earthworms. One that I maintained was very fond of nightcrawlers. When defending itself the body is usually coiled in a semi-circle and both head and tail are turned upwards—but only the head, with widely opened jaws, need be watched (LOL)..

 Female Collared Forest Geckos usually have prominently ringed tails.
This is another of the small but usually pretty geckos of the genus Gonatodes. The geckos of this genus are widespread in Tropical America as well as being present on many Caribbean Islands.
Although a bit less colorful than the related Bridled Forest Gecko, this Amazonian taxon, scientifically known as Gonatodes concinnatus, has derived its common name from the white to yellow bars on each side on the dark shoulders. It is the males that are so marked, the females having 6 or 7 chocolate and white transverse bars across the dorsum and usually also having white tail rings and tailtip. Males also have an unmarked brownish-yellow to orange head, shoulders, and forelimbs. Body ground color can vary. This species may be dark brown with faint lighter speckling or be exactly the opposite, being brownish-gold with dark speckling on the body.
Unlike its congener, the Collared Forest Gecko, this species seems seldom seen in camp clearings or on buildings, but is fairly common in the rainforest on stumps, fallen trees, and occasionally on broad shrub and tree leaves.
This is a small lizard, being about 3 ½ inches in total length. It is diurnal. A clutch consists of a single egg but several clutches may be produced annually.

 Although variable, male Bridled Forest Geckos are usually quite brilliantly colored.
It is often said that good things come in small packages, and this is certainly the case with the tiny geckos of the genus Gonatodes. Most are adult at an overall length of 3 ½ to 4 inches of which half is tail. IMO the little Amazonian species known as the Bridled Forest Gecko, G. humeralis, is a perfect example. I’ll admit that the females of all species in this genus are much less colorful than the males, and this is especially so when the males are in their breeding finery. The females are grayish with various darker markings and mottlings. Males, on the other hand, have an olive(ish) ground color dotted dorsally with pale to bright red and laterally with a mixture of black and reddish dots. Males also have a bridle-shaped marking of bluish-white as well as bluish-white markings atop the head, anterior to each eye and on the nosetip and yellow labial scales. These markings may all be pale when the lizard is quiet, but invariably brighten during courtship and actual breeding. A clutch consists of a single egg but several clutches may be produced annually.
Primarily diurnal, this little gecko is often seen on the buildings and plantings at Madre Selva Biological Preserve. It seems most common in clearings but is occasionally seen sleeping on broad-leafed plants in nearby rain-forest
As we move deeper into the rain-forest this species seems to be replaced by the Collared Forest Gecko, G. concinnatus.

 Large, gravid, and very dark in color, this Brown Water Snake was seen at canal edge in South Florida.The eastern USA is fortunate in having several species and subspecies of the genus Nerodia Water Snakes, as residents. Most are feisty if frightened, many will bite if carelessly restrained, and all are harmless (nonvenomous). Sadly, no matter how dissimilar they may look, many, if not most, are confused by those people who see them, with the venomous Cottonmouths. One that is most apt to be misidentified, is the Brown Watersnake, Nerodia taxispilota. It is also one that catches many folks by surprise.
The Brown Watersnake is one of the larger species, occasionally attaining 5 feet in length and being of heavy body. The color is variable, being brightest and most precise on neonates (yes, this is a live-bearing genus). Adults usually have a very visible pattern of light-edged dark dorsal blotches that alternate with light-edged lateral blotches. Some adults are very dark in overall color, especially when about to enter the shedding cycle.
Overall, the water snakes are semi-aquatic, but most are primarily water lovers. The Brown Water Snake, Nerodia taxispilota, may be seen basking in various riveredge situations including high in trees overhanging the water. From these perches, if startled, this big snake may drop into the water or, as too often happens, drop and land in the fishing boat that startled it. Sadly, when this happens this nonvenomous snake is often mistaken for the venomous cottonmouth and is summarily dispatched.
The light example seen here could probably be referred to as anerythristic (lacking red pigment)

 Yellow Amazon Tree boas were only occasionally seen on Madre Selva Preserve.
One of the first snake species that I saw at Madre Selva Biological Preserve was coiled high in the rafters of the old kitchen building. From my vantage point the snake appeared to be clad entirely in scales of “old rafter brown.” Tree Boa? Amazon Tree Boa? Could it really be? Could I be that lucky? Segundo, having been summoned, clambered up to the rafters, grasped the snake (that reacted in typical tree boa style) and was soundly bitten during his one-handed decent. He then handed the irate snake to me.
Since that first sighting, I’ve seen many Amazon Tree Boas, Corallus hortulanus, many of various shades of brown, some being brown and orange, other being yellow, and a few being a beautiful blood red. Some I caught, some Segundo caught, others by other of our guides. But somehow, somewhere during the photographing sessions, almost all of the snakes retaliated for having been disturbed and immortalized in a “toothsome” manner. Any of you who have kept these interesting boas will understand why I tell the participants on our herp tours, “Amazon Tree Boas just don’t play nice.”
But that has never dissuaded our tour groups or me from seeking the arboreal gems. Besides in the open-air buildings, we have found tree boas high in trees, others were dangling by their strongly prehensile tail, boa face at human face level, from vines that crisscross above our trails (if not noticed these could have resulted in a real “ouch encounter”). Others have been just coiled quietly atop stumps. On one trip, one of the dangling boas, a yellow example (pictured here) was seen on four of the six nights that we were at the preserve.
The tree boas found have varied in length from 18 inch juvies to 4 to 5 foot long adults.

 Broad-headed Skings were common in Okeetee. This male has assumed his seasonal breeding colors.
I don’t know how Gordy knew where we were but he did. The roadsign we had just passed informed us that Ridgeland was 20 miles ahead. And Ridgeland, in the state of South Carolina’s “Low Country,” was our goal.
This was way back in the mid-1950s and I was as “wound-up” as a young herper could be. I was an eager and avid herper, birder, and “everything-elser.” In other words, except for humans if it breathed, I wanted to learn about it, and herps were at the top of the list. And somewhere near Ridgeland there was a special place that Gordy had heard about---Okeetee Hunt Club. This was and is a 50,000 acre plot of land that came into being way back in 1894. Today it is fenced and patrolled and only members are allowed to enter. But back in the mid-1900s, back before today’s market hunters and the tendency to litigate every bruise or sprained ankle, anyone who wished could enter, and I was one of the lucky ones.
Besides being a refuge and gathering place for arms-bearing hunters, Okeetee was Mecca to a host of herpers. It was one of Karl Kauffeld’s favorite places and it quickly became one of Gordy’s and mine. And when you added on the several other nearby hunt clubs and preserves, the area became unbeatable. Corn snakes were common, as were Eastern Kingsnakes, Scarlet Kings, Hognoses, Eastern Diamondbacks and Canebrakes. Pine snakes were not uncommon; Broad-headed Skinks were abundant. Chorus Frogs ratcheted from nearby canal edges, Bird-voiced, Cope’s Gray, Barking and Green Treefrogs called from the Great Swamp. Oh, and did I mention that we often found Mud and Rainbow Snakes, and Red-bellied Water Snakes. The list goes on and on.
I’m glad that I actually got to experience those times now long gone. I wish the herpers of today, well.

 A young adult Pyxie Frog.Don’t be deceived by either the common or the scientific names. There is nothing—nothing at all --pyxie-ish about this frog. Adult males are every bit as large as the biggest of the Horned Frogs, Ceratophrys. They surpass in size the biggest American Bullfrog that I have seen, and are equally as voracious as any examples of either.
The frog we are discussing is the African Bullfrog Pyxicephalus adspersus. It is in the small family Pyxicephalidae. It has an immense range, including much of sub-Saharan Africa. The common name, of course, is derived from the genus name, and whoever decided on this scientific designation must have had a remarkable sense-of-humor. The Pyxie is cannibalistic, eats other frogs, rodents, and any invertebrates it happens across. Add to that the fact that it will latch rather painfully on to the errant finger of any careless keeper.
Possible lifespan is debatable. Some researchers say 20 years, others double that time span. It seems the frogs grow slowly, throughout much of their long lives. At adulthood male Pyxies may reach 10” in svl (snout-vent length). Females are smaller. Males are also a bit more brightly colored than the females. Males are a decided green and have a yellowish throat while the females are a much duller olive green to brown(ish)-green and have whitish throats. Juveniles are green with bright green vertebral and lateral stripes.Several rows of interrupted, elongate, dorsal and lateral ridges are present on both sexes.
Pyxies are secretive and spend much of their lives in burrows of their own construction. They are explosive breeders, emerging from their burrows to breed en-masse in temporary waterholes formed at the beginning of the rainy season. Sparring by the males is a common occurrence.
As an aside, hobbyists actually like this belligerent frog, and Pyxies are now being bred commercially for the pet trade.

 Not brightly colored, but IMO the finest of the Blue Tongues, Tiliqua nigrolutea.
Having well over 300 skink species, Australia could also be known as the “Great Land of Skinks.” These range in size from 4” long Garden Skinks and Pygmy Blue-Tongued Skinks to the remaining 5 species, all bulky blue-tongued species of the genus Tiliqua (one (possibly 2) additional species are extralimital). The Australian species are the Blotched, Common, Centralian, and Western Blue-tongues, and the Stump-tailed Skink, this latter now being considered one of the Blue-tongued skinks. These 5 vary individually within species from 16 to 23 inches in overall adult length.
Although we have kept several species, it is the Blotched Blue-tongue, Tiliqua nigrolutea, that is my favorite. Additionally, I favor the black (ground color) and buff (dorsal blotches and lateral reticulations) of the montane form over the paler colors of the lowland forms. Both forms are heavy-bodied, short-legged, diurnal, terrestrial, adult at 16-20”, live-bearing, long-lived (~20 years), placid, and hardy.
This skink adapts well to varying temperatures as well as eagerly accepting a wide variety of food items. Ours ate fruits, vegetables, canned dogfood, softened kibbled dog food, and they loved snails, slugs, and nightcrawlers. They often fold the hindlegs back towards the tail when moving about.
Females produced a single clutch annually, neonates numbering 3 to 8.
If you like responsive, hardy, captives, and if they are ever again legally available and affordable, consider a Blotched Blue-tongue. I don’t think you will be unhappy with the choice.

 This beautiful subadult Banded Gila Monster was just perched along a rocky trail.
The Gila (pronounced Hee-laa) Monster, Heloderma suspectum, is famous for its venomous bite. It is the only venomous lizard in the USA.
I find them appealing both for their appearance and the fact that they are unpredictable in their appearances in areas as different as rocky deserts, mountain slopes, and heavily populated areas. I rarely find them when I’m looking for them. But when I’m not actively looking, I may stumble across one or two.
This is a long lived lizard. A life span of 20 to 30 years is often quoted, but one researcher has been observing and documenting the same Gila Monster in her (he has determined it to be a female) on her winter refuge for more than 40 years. That’s right, 40+ years for that matriarch!
To highlight their unpredictability, on a recent trip to California, Jake and I had failed to find the White rattlesnake we had hoped to photograph and were returning to the car along our different trails. Suddenly Jake gave a holler, saying “come look at this!”
I clambered over to where Jake stood, and there amid the rocks on the trail was a beautiful young adult Gila. And what made this even better than good, it was a Banded Gila, H. s. cinctum, the westernmore subspecies that neither of us had seen in the field before. Cameras were activated and the lizard was immortalized as it crawled slowly to the ground and out of sight.
Elsewhere and at another time a Reticulated Gila, H. s. suspectum, the easternmost subspecies caught our eyes as it crawled, well after darkness had shrouded the Arizona desertland, along a sandy roadside. More pix, happy smiles, and more herping ahead. Life was good.
About the Gila Monster:
Subspecies and Range:
Banded, H. s. cinctum, Western Arizona, Extreme Southwestern Utah, Extreme Southern Nevada, possible isolated pops in Southeastern California
Reticulated, H. s. suspectum, Central and Southern Arizona, Extreme Southwestern New Mexico, Central and Southeastern Sonora
Color/Markings: Usually pink(ish) with black bands or reticulations
Size: Adults 18-22”; Hatchlings ~6”.
Appearance: “Chunky,” short-legged, relatively slow-moving. Tail about half as long as head and body and of variable thickness (the tail is a fat storage organ). This lizard is not capable of autotomizing the tail. Scales beadlike.
Status: Often seen but protected.

An FWC officer smiles as he surveys the scene after the killing of 34 pythons and a pregnant pet boa by FWC officers (Photo by Chris Coffee, who has granted permission for this photo to be published and disseminated)
In 2021, Florida changed their ownership laws but promised that pet owners were able to keep their animals for the lifetime of the animals. Breeders stopped breeding and started moving animals out of fear of repercussions. Animals that were legally owned under a "Conditional Species Permit" were now considered illegal, however according to FWC, they were grandfathered in for the rest of their lives and could live out their lives in their current homes.
"I want to make sure the public's aware that if you currently own one of these reptiles, you're allowed to keep it until it's death. So no one is telling you you have to get rid of your pet or euthanize it and no one from the state is going to take it from you." Rodney Barreto , Chairman - Florida Fish and Wildlife Conservation Commission - Public commission meeting February 25, 2021
"Their pets are their pets and they are going to continue to be their pets and we made sure that it was very clear." - Mike Sole, Former Vice Chairman - Florida Fish and Wildlife Conservation Commission, Public commission meeting February 25, 2021

 Even antheristic Corn Snakes very dark in color can be identified by the spearpoint on the top of the head.The Corn Snake, Pantherophis guttata, also known as the Red Rat Snake, is known to countless snake enthusiasts as a beautiful red, buff and yellow snake. Due to selective breeding in captivity, this species exceeds even the ball python in the variety of colors (and patterns).
But familiar though the hobbyists may be with the captive and normally red variations of this pretty constricting snake, many, many fewer realize that there are in the comparatively few wild areas left on the southern part of the Florida Peninsula, corn snakes of “a different color.”
Termed “anerythristic” (meaning lacking red), these snakes, pretty in their own modest way, have a variable ground color, gray with a brownish oversheen in most cases, to a pure dark gray on a few. Dorsal saddles and lateral blotches have brown centers with narrow to wide dark rimming. There is usually a dark edged, buff, postorbital bar present.
And while we’re discussing these, how did the name “Corn “ snake originate? It seems likely that this term describes the seemingly preferred habitat for this snake. It was and still is often found at the edges of agricultural (including corn) fields or in crop-storage barns.
Viva la Corn Snake!

 Yellow cheeks and reddish ears. We can only guess at the genetics.
Yellow-bellied Sliders, Trachemys scripta scripta, are among the more abundant of the sliders in the southeastern USA. At the northwestern areas of their extensive range they intergrade with the “once” more westerly Red-eared slider, T.s. elegans. I placed the word once in quotations simply to draw attention, for nowadays, due to releases and escapes, the Red-ear may be found not only throughout the range of the Yellow Belly but also far to the north and south of it as well. The two subspecies have much in common, not only genetically but in general appearance—they’re brightly colored as juveniles, have much the same carapacial appearance, darken appreciably (males the most) with age, attain the same adult size, and have plastral markings are almost the same. One sub species has red ear markings, the other has yellow facial blotches that are often suffused with some degree of red.
When Patti and I go across the street to the Wetland Park, one of the first herps we see are the Yellow-bellied Sliders. In early summer we can find hatchlings amidst the sedges at the shoreline. Throughout the days during all 4 seasons, as long as the sun is shining, we can usually scout out a half dozen or more adults basking atop floating vegetation or straddling emerging logs or floating alligators (‘gators also eat turtles). As I said, the taxon is common to the point of abundance, and we are glad this is so.
