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

Several years ago, we learned that female Caecilians (odd, legless amphibians) of some species grow extra layers of skin with which to feed their young.  This unbelievable feeding strategy was first documented on film in the BBC series Life in Cold Blood,  and is among the most fascinating (if chilling!) footage I’ve ever seen.  Tadpoles of the recently discovered Fringe-Limbed Treefrogs, Ecnomiohyla rabborum are now known to feed upon living skin as well.  In this case, it is the male parent that provides dinner with its own body – the only frog, and the only male amphibian, known to do so.

Discovery of a New Species

The Fringe-Limbed Treefrog is known only from a single mountainous rainforest in Coclé, central Panama.  It was first collected in 2005, and was described as a new species in 2008.  Its species name, rabborum, was given in honor of noted herpetologists Mary and George Rabb. Read More »

The larvae of the Black Soldier Fly, Hermetia illucens, have recently attracted a great deal of interest as a food item for herps, birds, fishes and invertebrates. Also sold as “Phoenixworms”, “Calciworms”, “Reptiworms” and “Soldier Grubs”, they are reputed to be superior to other insects in nutritional value. However, much of what has been written about them is confusing and contradictory. Today I’ll review the available research and my own and other’s experiences and attempt to sort fact from fiction, science from opinion.

Nutritional Analysis

There has been some work done on the nutritional value of Black Soldier Fly larvae, and the reports are promising. In fact, a number of zoos now use them regularly.

Most importantly, their Calcium:Phosphorus ratio is approximately 1.5:1 – very close the 2:1 ration that is generally accepted as ideal for most reptiles and amphibians (a poor Calcium:Phosphorus ratio is the main reason that calcium supplementation of crickets is recommended). Also, the actual calcium content of Soldier Fly Larvae is extraordinarily high – up to 8,155ppm as opposed to 20-135ppm in mealworms and crickets. Read More »

I usually hesitate to recommend an “all purpose” diet for any group of creatures, as even slight differences between species can be greatly affect their nutritional needs.  However, long experience with many newts has led me to a diet that works well for nearly all those that one might encounter.  The following feeding recommendations can applied to Eastern Spotted, Ribbed, Japanese Fire-Bellied, Alpine, Paddle-Tailed, Crested and Marbled Newts, as well as to Mexican Axolotls.  With a bit of fine-tuning, other species can be accommodated as well…please write in if you need further information.

Basic Diet

Newt-feeding is simplified by the fact that nearly all species will take non-living foods…this is in sharp contrast to terrestrial salamanders, which generally consume live prey only. Read More »

Most chameleons will eagerly accept crickets and mealworms.  However, even if you use reptile vitamin/mineral supplements, a diet comprised of 2-3 insect species is not suitable for chameleons – or for hardly any reptile or amphibian.  Your lizards will survive on such fare for awhile, but will inevitably develop nutritional disorders and die “long before their time”.  To avoid this, please read the following article before purchasing a chameleon; the information provided is applicable to Parson’s, Panther, Veiled and all other popularly-kept species.

Variety, an Essential Consideration

A varied diet is essential if you are to have success in keeping, much less breeding, chameleons long-term. The few field studies that have been done indicate that free-living chameleons consume dozens of invertebrate species.  Read More »

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 »
