Amphibian Abuse – Neon Dyed Frogs Wildly Popular in Chinese Pet Stores

Loggerhead TurtleMany turtle keepers here in the USA can recall seeing hatchling Red-Eared Sliders with gaily-painted shells being offered for sale at pet stores and carnivals.  Thankfully, through education and the passage of legislation, that practice, which killed thousands if not millions of turtles, is no longer with us.  Unfortunately, an equally-horrific new fad has recently popped up in China, where millions of young African Clawed Frogs are being colored with industrial dyes and sold as short-lived “novelties”.

Torturing Sensitive Creatures

A thin, sensitive skin pre-disposes frogs to a variety of environmental hazards, and may be one of the factors behind the recent extinctions of hundreds of species worldwide.  Permeable to water, oxygen and chemicals, frog skin is marvelous yet delicate, and easily irritated by any exposure to less-than-ideal environments.

So just imagine the effect of injections of industrial dyes!  Actually, any animal would be horribly injured or killed by such a practice…in fact, the dyes being used on the frogs are reportedly dangerous for people to handle.

As you can see from article linked below, the frogs take on neon hues of pink, yellow, green and other colors, and appear more like plastic toys than live animals – a situation that makes it more likely they will be treated as objects and not living creatures in need of care.

Larger Issues: Animals as Objects

In addition to the outright killing of frogs, the practice of dyeing them raises the larger issue of how they are perceived.  In this article, for example, the author has not even bothered to identify the type of frogs that are being sold, and even makes light of the situation – suggesting that the frogs sell-out so fast that prospective owners may need to dye their own!  The author callously goes on to note that the dyes should last 3-4 years “…by which time the frogs will probably be long dead anyway”.

As you can see by the video linked below, sellers also show little regard for the doomed creatures’ needs – the dyed frogs pictured there are held in a bare tank of filthy water in which float dead fishes.

A Life-Saving Frog

Ironically, so much of interest could have been written about African Clawed Frogs.  Once used as the basis for pregnancy tests (the Hogben Test), these frogs have been used in medical research for decades, and have saved countless human lives.  Captives become quite responsive and have lived for nearly 30 years, and educational kits featuring Clawed Frog tadpoles have introduced millions of school children to the wonders of metamorphosis.  I could go on…please see the article below for more on this most unique amphibian.

“Tiger Dogs” and other Odd Fads

Apparently, “plain” animals are not interesting enough for many modern-day consumers in China and elsewhere these days.  Fishes confined to lockets are still being sold, and in the past few years the practice of coloring dogs to resemble tigers, pandas and other creatures has become fashionable (please see article below).

Reporting Animal Abuse

Please read my article on Reporting Animal Abuse (USA), and of course feel free to write in for advice; in most cases I’ll be able to direct you to an appropriate local authority if you have witnessed animal cruelty or abuse.

The Natural History and Captive Care of the Green and Black Poison Frog

Black and green PA FrogI’ve always favored the boldly-marked Green and Black Poison (or “Dart”) Frog, Dendrobates auratus, over most of its relatives.  This was a turn of good fortune for me, as this gorgeous creature is one of the largest and easiest of the poison frogs to maintain.  It is also not at all shy – while working in Costa Rica, I was surprised at how easy wild ones were to observe – and makes a wonderful exhibit animal.  Green and Black Poison Frogs have become almost common in the trade, yet many remain unaware of some surprising aspects of their lives in the wild.

Little-Known Facts

First a few notes that have surprised me over the years.

Hobbyists accustomed to seeing these frogs in terrariums may be surprised to learn that wild specimens sometimes venture into forest canopies over 100 feet above ground…quite a climb for a minute frog!  Read More »

Feeding African Clawed Frogs – the Two Best Diets

African Clawed FrogProviding a wide variety of live foods is one of the main stumbling blocks to keeping most frogs healthy in captivity.  African Clawed Frogs (Xenopus laevis, and several related species), however, take non-living foods (i.e. carrion) in the wild, and therefore are quite easy to accommodate in captivity.  Today I’d like to highlight two different diets that have enabled some of my African Clawed Frogs to reach 20+ years of age, and to breed as well.

Note: Dwarf African Frogs, Hymenochirus spp., require an entirely different diet comprised of small live invertebrates.  Please see this article for details.  Another relative, the bizarre, skin-brooding Surinam Toad, Pipa pipa, is also a live food specialist (please see photo and this article.

Frog Leg Trade Kills Billions of Frogs Annually and Threatens Species’ Survival

Indian BullfrogUnprecedented declines in amphibian populations have been much in the news lately.  Linked to a number of factors, including an emerging disease (Chytrid fungus infection), frog extinctions are being documented the world over, and herpetologists are scrambling to save those that remain.  Yet the international trade in frog legs remains largely unregulated, and is considered by many to serve only a limited market for “exotic foods”. However, a recent report, Canapés to Extinction: the International Trade in Frog’s Legs (July 26, 2011) reveals the trade’s shocking volume and impact on frogs and their habitats.

Trade Kills 1,000,000,000+ Frogs in US Alone

The extent of the frog leg trade in the USAis surprisingly large.  The USAannually imports 4.6 million pounds of frog legs, representing an estimated 1.1 billion frogs, and 4.4 million pounds of live frogs!   These figures, and those mentioned below, are bare minimums, as they do not include locally farmed and collected frogs and those that are not reported to regulatory authorities.  Read More »

Strange but True – Fringe-Limbed Treefrog Tadpoles Consume Father’s Skin

Drawing of a Flying FrogSeveral 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 »
