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

This article is one of a series in which I plan to provide a brief introduction to both popular and rarely-kept amphibians, reptiles and invertebrates.  I’ll cover such topics as unique habits in the wild, common mistakes or concerns in captive care, pet pros and cons, little-known husbandry tips and so forth.  Detailed care articles will follow…until then, I would enjoy receiving your questions and comments.  Today we’ll take a look at the Red-Eyed Treefrog, Agalychnis callidryas.

Night Shows Only!

Ranging from southern Mexico to Panama, this striking beauty (its scientific name translates as “Beautiful Tree Nymph”) has become something of a “rain forest darling”, appearing on more calendars, book covers and travel brochures than any other amphibian.  Frog keepers, enamored of its huge, brilliant red eyes and lime-green skin, have taken to it as well.  Read More »

Herpetologists at Panama’s Smithsonian Tropical Research Institute have uncovered a here-to-fore unknown form of communication among frogs. Using robotic frogs, infra-red lights and accelerometers, they have established that male Red-Eyed Treefrogs (Agalychnis callidryas) compete by shaking their bodies, which in turn vibrates the plant stems upon which they are perched.

Vibration Contests

Writing in the May 20, 2010 edition of Current Biology, researchers speculate that the vibrations sent through plant stems enable other male frogs can access the plant shaker’s intent, size and status. It appears that the frogs’ vocal calls may also vibrate plants, but further research is needed.

Additional studies are also being planned to determine if other herps, birds or mammals utilize vibration-based communication (invertebrates are known to do so). Read More »
