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

Most invertebrate keepers have noticed that individuals of the same species often behave quite differently under the same circumstances.  For example, one Giant Bird-Eating Spider might feed in broad daylight and be content to remain in the open, while another refuses to eat unless provided with a deep burrow and complete darkness – I can recall countless similar observations.  Does this mean that these “simple” creatures have personalities?  According to a recent study, the answer may be “yes”…

How Does One Test Insect Personalities?

An article published in the September, 2010 issue of The Proceedings of the Royal Society (B), reveals that individual insects exhibit distinct personality traits, and that these traits remain consistent in different situations. Read More »

Hundreds of amphibian species have been drive to extinction in recent years, and an estimated 30% of those remaining may soon follow.  Because most are difficult to find, herpetologists are now asking the public’s help in locating 100 species that are considered extinct but may still hold on in small numbers.

The recovery effort, launched this month (August, 2010) by Conservation International and the IUCN, spans the globe.  Even questionable sightings and photos are welcome –after all, a dog in Montana tipped researchers to the fact that the Black-Footed Ferret was not extinct (by killing one!), so you never know…

There is even a “10 Most Wanted List”, the members of which I’ll describe below. Read More »

An article in the August, 2010 issue of Zootaxa announces that a recently discovered frog is the smallest species in the Eastern Hemisphere.  Known only as Microhyla nepenthicola, the minute native of Borneo is barely the size of a green pea!  Interestingly, specimens have been in museum collections for over 100 years, but they were believed to be immature individuals of other species.

A Pitcher Plant Specialist

The tiny amphibian breeds in a unique habitat – the water contained in the base of pitcher plants.  Pitcher “ponds”, which serve to drown insects that are digested by the plants, support miniature ecosystems inhabited by insect larvae, snails, crabs, algae and other organisms.  Read More »

Many of the most interesting reptile 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 covers Spring, 2010 publications: Common Snapping Turtles (Chelydra serpentina), Texas Horned Lizards (Phrynosoma cornuta), Italian Wall Lizards (Podarcis siculus) and Eastern Kingsnakes (Lampropeltis getula).

Working with Green Anacondas (Eunectes murinus) in the Bronx Zoo and participating in a capture/tagging project in Venezuela was a childhood dream come true.  While I cannot recommend a potentially deadly behemoth as a pet, interest in them is always high…today I’ll highlight the natural history of this impressive giant.

Description

A stout animal that may exceed 400 pounds in weight, this is the world’s heaviest snake.  It vies with the Reticulated Python for the title of longest serpent.

In the past, 25-foot-long animals were encountered, but an individual approaching 20 feet is considered large today.  There is a fairly reliable record of a 33-foot-long Green Anaconda; an unverified field report from Eastern Columbia (1944) claims an individual of 37.5 feet.  In the course of tagging over 500 specimens, the largest I and my co-workers encountered in Western Venezuela was just over 17 feet long and tipped the scale at 215 pounds.  Read More »
