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

I’ve found the Penn Plax Turtle Pier to be one of the most useful of all basking platforms.  In addition to providing a haul-out site that does not take away from the swimming area, it can be used by reptiles and amphibians in a variety of other ways.  Today I’d like to describe two “fine points” that are sometimes over-looked when semi-aquatic terrariums are designed.

Sub-Surface Resting and Basking Spots

Many semi-aquatic turtles do not often fully emerge from the water, but rather rely upon resting sites that are just below the surface.  Included among these are Mud, Musk, Snapping and Chinese Big-Headed Turtles.  In the wild, these turtles, as well as Green Frogs, Ribbed Newts and many other amphibians, rest upon submerged logs, branches and rocks that almost, but not quite, reach the water’s surface.  From such locations, they can watch for predators and prey and, possibly, obtain some UVB exposure (UVB rays do not penetrate very far into water).  In aquariums, driftwood is also useful in this regard…please see the article below.

Salamanders are by no means defenseless – indeed, the skin toxins produced by the California Newt and its relatives are among the most virulent natural chemicals known.  But most herpers tend to regard them as small, slow-moving, inoffensive beasts.  Not so the mighty Greater Siren, Siren lacertina.  This caudate “rule-breaker” can bite viciously in self defense, and is a major predator in its environment…but it is also among the most interesting amphibians that one can keep, and very hardy to boot.

Description

The long, eel-like body is grey or olive to near-black in color.  Measuring up to 38.5 inches in length, Greater Sirens are among the world’s longest salamanders.  They are exceeded in length only by the Two-toed Amphiuma (also native to the USA) and the Japanese and Chinese Giant Salamanders.  Read More »

Global amphibian declines and extinctions spurred herpetologists to pay special attention to frogs, salamanders and caecilians in 2010.  In Part 1 of this article, I reported on the discovery of several new species, and the re-discovery of a few that had not been seen for decades.  Today we’ll look at interesting findings concerning a well-known salamander that houses algae in its cells and a rarely- seen species that lives for over 100 years.

Algae in Salamander Cells

It’s long been known that algae growing within the egg masses of Spotted Salamanders, Ambystoma maculatum, provides oxygen to the embryos and utilizes their waste products.  In 2010, however, Dalhousie University (Canada) biologists shocked the herp world by announcing that they had found living algae within Spotted Salamander cells, functioning as it does in the egg mass.  This is the closest known association between a vertebrate and a plant, mimicking in some ways the relationship between algae and coral.

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 »

In the wake of continuing amphibian extinctions, herpetologists made a special effort to study frogs and salamanders in 2010.  Their hard work resulted in the discovery of new species and others believed extinct, and in many surprising new findings about how they live.

Please note: the species described below are barely studied; the photos shown here are of close relatives.  Please see article below for actual photos.

“Back From Extinction”

Biologists participating in a program launched by Conservation International and the IUCN combed the globe in hopes of finding amphibians that have already been “written off” as gone forever.  Herp enthusiasts were pleased to learn that at least 3 of these, while very rare, do indeed continue to hold on.
