The Natural History and Captive Care of the Rhinoceros Iguana

Male Rhino IguanaRhinoceros Iguanas (Cyclura cornuta cornuta) rank among the most “personable” of the lizards I’ve worked with.  However, due to their size, unique needs and powerful jaws (please see below), the decision to keep these magnificent animals must not be made lightly.

Description

The “bulldog-like” body is stoutly-built and colored uniform gray, brown, olive-brown or nearly-black.  Rhinoceros Iguanas reach 4 feet in length, but appear larger due to their bulk.

The massive head of the male is topped by 3 horn-like tubercles and a thick adipose (fat) pad.  The head and horns of females are smaller. Both sexes have large throat pouches and crests of pointed scales along the spine and tail.  Read More »

The Eastern Newt – the Many Subspecies and Hybrids of a Popular Pet – Part 2

Quite a few subspecies of the Eastern Newt (Notopthalmus viridescens) have made their way into the pet trade.  All are hardy, interesting and possible to breed in captivity.  Please see Part 1 of this article for information on their care and feeding.  The following descriptions and habitat information should help in identifying your newt.  However, natural and captive-generated hybrids can complicate the process – please write in if you need assistance.

Fungal Infections (Mycotic Disease) in Reptiles – Part 2

Green Tree PythonThe dangers posed by fungal infections are well-known to amphibian and fish keepers.  A number of fungi also attack reptiles, but many have proven difficult to detect and treat.  In Part 1 of this article I discussed how stress predisposes reptiles to attack and fungal infections in desert-adapted reptiles.

Rainforest Reptiles

Reptiles adapted to rainforests and other humid environments are not immune to fungal attack, despite the fact that fungi are common in their natural habitats.  Problems were first noted in Green Tree Pythons housed in enclosures that allowed for little air circulation.  Subsequently, we learned that these snakes must have humidity as well as air circulation if they are to remain free of respiratory infections.  I have found the same to hold true for Green Tree Boas, among others.

Frog Diets – Nutritious Foods for Popularly-Kept Frogs and Toads – Part 1

Albino BullfrogsMany frogs and toads that are collected or purchased and kept as pets will greedily accept crickets and mealworms, the food items most easily obtained from pet stores.  Most thrive on this fare for a time, but eventually develop nutritional disorders and expire long before they have reached their potential life-span.  Following are some useful tips for those keeping American Bullfrogs, White’s Treefrogs, Budgett’s Frogs, most Toads and similar species.  Please see my other Amphibian Care Articles for information on feeding Poison Frogs, Mantellas, African Clawed Frogs, Horned Frogs and others requiring specialized diets, or write in with your questions.
