That Reptile Blog – Reptile, Amphibian and Exotic Pet Care and Information

Many interesting field research reports are published in professional journals such as Copeia, Herpetologica and Herpetological Review, and are not available on the internet.  From time to time I’ll provide summaries of some of the fascinating articles that I come across.  Today’s report, drawn from Autumn, 2010 publications, covers observations of free-living snakes, turtles and caimans.

Giant Meals…even for snakes!

Snakes are “big meal specialists”, but rarely consume animals larger than themselves.  However, a Southern Toad and a Spadefoot Toad, swallowed by different Eastern Hog-nosed Snakes, Heterodon platyrinos, each outweighed the snake by several grams!  Read More »

 A recent article in the journal IRCF Reptiles and Amphibians (V17, 1) provides evidence that the African Rock Python (Northern African Python, Python sebae), may have established a breeding population in southern Florida.  The huge constrictors are adapted to take small antelopes and other large animals, and have been killed and consumed people in their native habitat.

Florida’s Introduced Constrictors

At least 45 species of non-native reptiles and amphibians have established breeding populations in Florida; many others have been observed but are not known to be reproducing.  Among these are 2 of the world’s largest snakes, the Burmese Python and the Boa Constrictor.  Other large constrictors, including the Green Anaconda, Yellow Anaconda and White-Lipped Python, have been found at large in Florida.  Read More »

The herpetology world lost one of its oldest and most celebrated members with the passing of the legendary Bill Haast on June 15, 2011.  Although surrounded by controversy for (literally!) most of his 100 years, Mr. Haast inspired millions of reptile enthusiasts, myself included, and saved countless lives by harvesting the venom needed to produce antivenin (the medicine used to treat bites from venomous snakes). He even donated his own blood, which he believed to contain antivenin, to snakebite victims (please see below). Read More »

The Trans-Pecos Ratsnake, Bogertophis subocularis, stands apart form it’s many relatives in both appearance and habits.  Please see Part 1 of this article to learn more about the natural history of this most interesting desert-dweller.

General Care

Although less closely related to the “typical” ratsnakes (i.e. the Yellow Ratsnake, please see photo) than originally believed, the basic care of the Trans-Pecos closely follows that of other commonly kept species.  Please see the article below for general care; today I’ll focus on points specific to the Trans-Pecos Ratsnake.

North America is home to a great diversity of ratsnakes, many of which have long been bred in captivity.  One of the more unique species to have become established in the trade is the Trans-Pecos Ratsnake, Bogertophis (formerly Elaphe) subocularis.  Despite wide availability, its life in the wild remains largely unstudied.  Today we’ll examine what is known of its natural history, and move on to care and breeding in Part 2.

Description

The Trans-Pecos Ratsnake ranges in color from almost pure yellow to yellowish-olive or tan, and is one of the few snakes clad mainly in this color.  It is further distinguished by dark-brown to black “H” shaped blotches between 2 long dorsal stripes and by unusually large, bulging eyes (a likely adaptation to its nocturnal lifestyle).  Light or “blond” and dark phases occur naturally, and at least 18 color varieties have been produced in captivity.  Adult Trans-Pecos Ratsnakes measure 3 to 5½ feet in length.
