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

During my years with the Bronx Zoo, I have twice observed cold temperatures to revive salamanders (a Hellbender and a Greater Siren, please see photo) that seemed, by external appearances, to be quite dead.  A recent paper caused me to think back on these events, and to other examples of low temperatures being used to “treat” ailing Axolotls, Leopard Frogs and other amphibians …I would greatly appreciate your own observations and thoughts on this topic.

Cold Tolerant Amphibians

Many amphibians are well-adapted to surprisingly low temperatures.  On Long Island, NY, Eastern Tiger Salamanders may migrate to breeding ponds in February, and Spotted and Alpine Salamanders will cross snow for the same purpose.  Wood Frogs occur within the Arctic Circle, and I’ve found Gray Tree Frogs hibernating beneath a mere 2” of leaf litter in NYC.  Several Fire Salamanders under my care remained active at 38 F.

Although my interests are wide, newts and salamanders have always held a special fascination for me.  Beginning in childhood, I sought to keep and breed as many species as possible, and I focused on their husbandry and conservation when I entered the zoo field.  In time, I wrote a book summarizing my experiences (please see below).  The passage of so many years has not dulled my enthusiasm for these fascinating amphibians, and I can highly recommend them to both beginning and advanced herp keepers.

The following information may be applied to the care of Japanese Fire-Bellied, Eastern, California, Ribbed and Paddle-Tailed Newts, as well as most others that appear in the pet trade.  Please write in for detailed information on individual species.

Newts as Pets

An ability to thrive on commercial pellets distinguishes newts from other amphibians, and endears them to folks who prefer not to handle live insects.  All are brilliantly-colored, active by day, and usually live well in groups at average room temperatures.  Most become quite tame over time, and will even accept food from your hand.  Several California Newts in my collection have lived to age 20, and others seem bent on exceeding that.

A recent study has challenged what we know, or thought we knew, about frog communication.  Researchers were astonished to discover that the calls of male Emei Music Frogs, (Babina daunchina) inform females of such details as the length and width of the singer’s burrow.

Construction Skills Needed

Named for the males’ banjo-like calls (they really do sound like banjos, please check video below), the Emei Music Frog is native to marshy habitats in central and southwestern China.  Females deposit their eggs in burrows constructed by the males, and the tadpoles develop there as well.  The ability to construct a safe burrow is, therefore, an important consideration when females go “mate shopping”.  You can see photos of the unique nests and egg masses of a related species, Japan’s Ryuku Brown Frog, here.

The Domestic, Brown or House Cricket, Acheta domesticus, is the most widely-used live food for reptiles, amphibians, tarantulas, scorpions and other pets. At once hardy and delicate, it eats just about anything and is easy to breed, yet a colony can be wiped out in hours if conditions are not perfect.  Whether you need only to keep a few alive so that they can feed for several days (thereby increasing their nutritional value) or plan to save money by ordering in bulk or breeding your own crickets, die-offs can be avoided if you follow a few simple rules.

Primary Concerns

Poor ventilation, crowded conditions and high humidity are the most common reasons for cricket colony failures. These three factors are related to one another, and will be discussed below.

Natural History

Domestic Crickets are native to southwestern Asia. Escapees have established populations throughout the world, usually in close association with people. Their taxonomic order, Orthoptera, contains over 20,000 grasshoppers, katydids and related insects.

The USA is home to over 120 cricket species; my favorites, the bizarre Mole Crickets, tunnel below-ground with spade-like front legs (please see photo).  Over 3,000 species have been described worldwide. New Zealand’s “super cricket”, the Giant Weta, is the world’s heaviest insect…at 70 grams, it weighs as much as a House Sparrow!  Read More »

Turtle enthusiasts seem always to remain interested in even the commonest species. I’ve worked with world-renowned herpetologists who keep Sliders and private breeders who care for 2,000+ turtles (not a misprint!) yet find a place for Common Snappers.  I’m the same way…as I write, I’m watched by a Stinkpot that I acquired in 1969.  Yet there’s no denying the allure of 4 foot-long Giant Softshells, 200+ lb. Alligator Snappers, massive Painted River Terrapins and other rare giants like the turtle I’m holding in this photo (a Mata Mata rescued from a food market; the largest I’ve seen, perhaps a record). Today I’d like to share some experiences I’ve been lucky enough to have had with these and others. Don’t miss the chance to visit collections housing these amazing creatures; volunteer opportunities with field research programs are also sometimes available.

In 1985, while a reptile keeper at the Bronx Zoo, the opening of a 77,000 gallon Asian river exhibit (at Jungle World), allowed us to work with large turtles on a grand scale. Another unique opportunity came in 1997, with the seizure of nearly 10,000 turtles in Guangzhou, China. Many were sent to the USA, where I and others helped to place them in private and public collections.  Read More »
