Brightly colored and beautiful, this Giant Dwarf boa still retains the even brighter tailtip used in luring their prey of anurans and lizards into striking range.
It seems as if all too often the world’s herpetoculture hobby centers on the almighty dollar. In the 70+ years I have been involved with herps I have seen so many species come and go that I would be at a loss if asked to name them all. But since I’ve been on a “Dwarf Boa” kick for the last few months I’ll just mention one of them—the Giant Trope, Tropidophis melanurus. Since mentioning several species of this genus in my blogs, I have had a number of queries asking about their availability in the American hobby. The answer has been and will seemingly continue to be, they are now longer available. Why? Because hobbyists have chosen to breed more prolific snake species that are easier to breed than the Giant Trope was. Think $$$!

By the way, the term giant pertains to the adult size of T. melanurus as compared to other species in the genus. The adult size of this “giant” varies from about 26 to 36 inches but it is of rather heavy girth. Although it is often of light mud color, some (rather rarely seen) examples are much brighter. It was these, of course, that were being captive bred and available to hobbyists. But sadly, even though easily kept and bred, these little snakes had small litters (usually only 2 to 5) and they disappeared from the American hobby decades ago but it is a commonly seen species in the wilds of Cuba. Prey includes frogs, toads, lizards, and nestling rodents.

And just as a heads up, all species of Tropidophis are capable of, and prone to, autohaemorrhage from the mouth, nostrils and eyes if unduly disturbed.

Stiletto snakes lack an enlarged head but are venomous, and have a short, stout, tail tipped with a spiny scale.
To see any of the several species of African/Mid-Eastern Stiletto Snakes, one would think that they were viewing a harmless little black burrowing snake species. When uncovered these 15 to 26 inch long snakes try immediately to cover themselves again and will quickly succeed unless impeded by substrate or human. All 15+ (according to geneticists there may be 20 or more species) are fast and they are squirmy. They do not have an enlarged head but, heed this hobbyists and systematists) they are venomous and almost impossible, thanks to greatly elongate fangs that slide easily under and beside the upper labial scales, to handle without sustaining a bite. Venom is produced in small quantities but is considered dangerously toxic and is known to cause severe pain. These little burrowers preferentially feed on burrowing reptiles (seemingly on lizards) but will accept nestling mice as well.

It seems that it is the Southern Stiletto Snake, Atractaspis bibroni, that is most often (now rarely) available to American hobbyists and is pictured here.

Our 5th Trope species of the trip, the Leopard (or Dark Spotted Brown) Trope.
We had looked for Tropidophis pardalis, the Leopard Trope (the genus was formerly recognized as Dwarf Boas) on at least 5 of our Cuban herping/birding excursions, but had never made a truly dedicated search. Although certain we were well within the range of this species we had flipped many rocks and fallen tree corpses but had failed on every occasion. We had seen birds galore—todys, trogons, lizard cuckoos and others, we had seen various lizards and some endangered plants, but zero dwarf boas.

But on this occasion, on the last day of our last trip of 2022, I elected to do something a bit different. The other trip participants again climbed the rather treacherous rock-strewn trail with our group leader, Dr. Luis M. Diaz, but I was going to remain near the entrance and search out turnable rocks on the very muddy substrate. I was positive, after having long discussions with Dr. Diaz and Nils Navarro, that Leopard Tropes were in residence and our failures to find them were merely the quirk of fate known well to all herpers.

My compadres were soon out of sight up the trail. I turned 1 rock, then the second. Only arthropods and oozing mud were seen. I walked slowly through the gate and was confronted with mud and puddles, and in the distance one mud-covered rock resting ankle deep in slurpy-mud. I sloshed over, managed to flip it, and before the water sought its depth there, saw a little brown mud-splattered ball—our first Leopard Trope! And as luck would have it, Luis found a second example higher on the trail. It, too, was beneath a muddy rock.

As well as being hardy, Standing's Day Geckos tame readily.
Seems the best way to describe this Malagasy beauty is to simply call it what it was--the biggest and the best of that diverse genus. True, it might be equaled in length by a male Giant Day Gecko, Phelsuma madagascariensis grandis, but Standing’s Day Gecko, P. standingi, is bulkier. When properly fed, a captive lifespan of 15 to 20+ years is not uncommon. In this genus of bright green geckos, that it was not the most colorful was obvious. But color isn’t everything, and the hatchlings, with their green heads, red-banded body, and blue tail, more than make up for the muted greens, blues, and grays of the adults. Additionally, after gentle acclimatization this 9 to 11+ inch long gecko is of a relatively quiet, unafraid, demeanor and often allows gentle handling. All said, it is an ideal pet lizard.

Like other species in this genus of about 70 species, Standing’s Day Gecko is largely diurnal and arboreal. Two larger species once existed but are now considered extinct and the blame is laid on habitat destruction. In nature this gecko not only licks nectar and pollen and fruit, but also consumes a fair number of insects and an occasional small vertebrate. Captives will readily eat insects and prepared Day Gecko Food.

Ours were housed in a 65 gallon hexagonal aquarium set up with vertical and diagonal hollow limbs, growing plants, and an easily accessed feeding platform. They drank droplets of water from the glass. Not until their deaths at a ripe old ages did we part.

Several clutches were produced annually by adult females. Eggs may be produced singly or in pairs.
