Amphibian News – Rare Frogs Breed in Captivity, Lost Species Found

Haitian LandscapeFrogs 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.

Inexpensive Homes for Sliders, Painted Turtles and other Semi-Aquatic Species – Part 1

Black Knobbed Map TurtleFrom simple, easily-cleaned habitats to complex environments, herp enthusiasts have many options when it comes to setting up terrariums for reptiles and amphibians.  Today I’ll cover everything you’ll need to create an ideal habitat for semi-aquatic, basking turtles, including Red-Eared Sliders, Painted and Map Turtles, Cooters and others.  With a bit of modification, your set-up can also accommodate largely-aquatic species such as Musk, African Mud, Snapping and Soft-shelled Turtles.  I’ll also mention money-saving alternatives to certain products, along with non-essential “extras” that can be added if you wish.

Enclosure

Surface area, to allow for swimming and bottom “prowling”, is a more important consideration than water depth for most species. Read More »

The Natural History and Captive Care of the Trans-Pecos Rat Snake – Part 1

Trans Pecos Rat SnakeNorth America is home to a great diversity of ratsnakes, many of which have long been bred in captivity.  One of the more unique species to have become established in the trade is the Trans-Pecos Ratsnake, Bogertophis (formerly Elaphe) subocularis.  Despite wide availability, its life in the wild remains largely unstudied.  Today we’ll examine what is known of its natural history, and move on to care and breeding in Part 2.

Description

The Trans-Pecos Ratsnake ranges in color from almost pure yellow to yellowish-olive or tan, and is one of the few snakes clad mainly in this color.  It is further distinguished by dark-brown to black “H” shaped blotches between 2 long dorsal stripes and by unusually large, bulging eyes (a likely adaptation to its nocturnal lifestyle).  Light or “blond” and dark phases occur naturally, and at least 18 color varieties have been produced in captivity.  Adult Trans-Pecos Ratsnakes measure 3 to 5½ feet in length.
