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 »

Pythons and boas bear small spurs, used by males during courtship, near the cloaca (please see photo).  These vestigial legs provide us with evidence that snakes may once have walked about on 4 limbs, but until recently we could only speculate as to further details.  However, new technology has now enabled us to fill in some of the blanks, and may offer insights into other creatures that seem to be “losing their legs”, such as Worm Lizards and Sirens.

Snake Ancestors

Utilizing a developing technology known as Synchrotron-Radiation Computed Laminography, researchers at the Paris Museum of Natural History were able to microscopically examine snake fossils in new detail.  They concluded that swimming or burrowing lizards were the most likely ancestors of modern-day snakes.

Inspired by fellow Bronxite John Kiernan’s wonderful book A Natural History of New York City, I have searched for reptiles and amphibians in just about every corner of the Big Apple.  An amazing array of species manage to hold on here and in other cities around the world (Reticulated Pythons are regularly encountered in Singapore and Bangkok) – in fact, I cannot cover all of NYC’s species in a single article.  Today I’ll take a look at big city snakes.

Snakes of NY State

New York State is home to 17-18 species of snakes, most of which once dwelled within NYC limits. Three of these – the Copperhead, Timber Rattlesnake and Eastern Massasauga – are venomous.  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 »
