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 a favorite topic of mine – feeding records.  As theses reports show, snakes and frogs often do battle – and the results are hard to predict!

Fer-de-lance and Smoky Jungle Frogs: Venom vs. Poison

In Costa Rica, a Fer-de-lance partially swallowed and regurgitated a Smoky Jungle Frog.  The snake was rendered lethargic incapable of defending itself for at least 45 minutes (and would likely not repeat the experience!).  Smoky Jungle Frogs produce Leptotoxin, a powerful chemical that causes rapid death from cardiac arrest when administered to rats.  People have reported experiencing “tingling” sensations after handling Smoky Jungle Frogs.

Frogs and frog enthusiasts have much to celebrate these days.  The endangered Lake Titicaca Frog, Telmatobius culeus, has reproduced in captivity, and 6 Haitian frogs, lost to science for decades, have been found.

Lake Titicaca’s Aquatic Giant

The huge, skin-breathing, cold-adapted Lake Titicaca Frog ranks as one of the world’s strangest amphibians.  Known only from this lake, which straddles the Peru-Bolivia border at 12,500 feet above sea level, the unique creature is threatened by the food trade and pollution.

I had the good fortune to work with what was, at the time, the only Lake Titicaca Frogs in captivity.  Despite nearly 2 decades of trials, I and my co-workers failed to raise the few tadpoles that were produced (please see article below).  However, Peru’s Huachipa Zoo, in association with the Denver Zoo, has announced that 5 apparently healthy tadpoles are now being reared.  A museum in Bolivia has been successful in breeding a close relative, the equally-rare Water Frog, Telmatobius hintoni.

I’ve recently observed several frogs and toads to develop difficulties in feeding (American Bullfrogs, Gray Treefrogs, Southern Leopard and Green Frogs; several readers have written to me concerning difficulties with American Toads).  It starts with what looks like “bad aim” and progresses to the point where the frogs cannot catch insects at all and must be force-fed.  I’ve looked into the problem and found that a Vitamin A deficiency, leading to Short Tongue Syndrome, may be involved (please see this article by Dr. Kevin Wright of the Arizona Exotic Animal Hospital for details).  I’d like to request that readers send me their own observations, so that we can learn more about this serious amphibian health problem.

The year 2011 has barely begun, but it is already supplying amphibian enthusiasts with exciting news items.  One of the most surprising is the discovery that the tadpoles of the newly-described Vampire Flying Frog, Rhacophorus vampyrus, sport hard, sharp fangs…a previously unknown amphibian adaptation.

A Surprise in the Treetops

Biologists from Australia, Vietnam and the USA (North Carolina Museum of Natural Sciences) uncovered the new frog and its odd tadpoles while surveying montane forest canopies on the Langbian Plateau in southern Vietnam.  Their findings, published in the journal Zootaxa (please see article below), have left herpetologists wondering just why tadpoles might need such odd mouthparts…certainly not to puncture veins, as their common name suggests!

In Part 1 of this article we discussed vitamin/mineral supplements for aquatic animals that accept prepared/non-living foods; included among these are African Clawed Frogs, Sharp-Ribbed and many other newts, and most water-dwelling turtles.

Live Prey Specialists

Animals that take live prey only are especially troublesome when it comes to supplementation, as one cannot coat live aquatic food animals with powders.  Popular live food specialists include Dwarf African Clawed Frogs, Mata Mata Turtles, Surinam Toads, Mudpuppies and the larvae of most salamanders.  Read More »
