Chameleons as Pets – an Overview of their Natural History and Captive Care

Chamaeleo calyptratusChameleons, the most unique of all lizards, are truly marvelous creatures to know and care for.  In the past, I’ve written about Veiled, Dwarf and Senegal Chameleons, and related topics (please see articles below).  Today I’d like to discuss some general principals of chameleon care.

The following information can be applied to most available Chameleons; however, details will vary.  Please write in for specific information on individual species.

Natural History

To date, 186 Chameleon species have been described (Family Chamaeleonidae).   They range in size from the 1.5 inch-long Pygmy Leaf Chameleons (Rhampholeon spp.) to the Oustalet’s Chameleon (Furcifer oustaleti), which may top 30 inches in length.

Unique characteristics include a tongue that may exceed the animal’s length, mobile eyes, a “swaying” walk that mimics wind-ruffled leaves, joined toes that form grasping “hands”, a prehensile tail and remarkable color-changing abilities.  Color changes are mainly used to communicate, but also serve as camouflage.  Read More »

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.

Hatching Praying Mantid Egg Cases to Feed Tiny Amphibians and Invertebrates

Mantis Laying EggsDietary variety is the key to success in rearing many herps and invertebrates.  Unfortunately, options for newly-transformed frogs and salamanders, Poison Frogs and other small species and hatchling spiders are limited. A diet of fruit flies, springtails and pinhead crickets sometimes suffices, but as I learned when rearing the endangered Kihansi Spray Toad, other foods are often necessary.  Praying Mantid Egg cases (properly termed “oothecum”), which may be collected or ordered from commercial dealers, are a useful but under-appreciated resource for those who keep small insectivorous pets.

Foreign Mantids in the USA

The 2 most-commonly encountered mantids (or mantises) in the USA are both introduced (not native).  The largest and most widespread is the Chinese Mantid, Tenodera aridifolia sinensis, brought here in 1896 to battle insect pests.  The European or Praying Mantid, Mantis religiosa, arrived as a stowaway around the same time.  They and the world’s other 2,400+ species, consume vast numbers of beneficial and harmful insects…in fact, a single Chinese Mantid may consume 20,000 or more insects in its lifetime!

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 »

Gulf Oil Spill Update – Sea Turtles and Other Wildlife Still Face Threats

Ridley’s TurtleFive species of sea turtle, all threatened or endangered, inhabit waters affected by the April, 2010 oil spill in the Gulf of Mexico. In the 20 months that have passed since, many have been rescued, but problems still linger. Unfortunately, we cannot yet determine how this ecological nightmare has affected their survival prospects.

It is estimated that over 6,000 sea turtles of 5 species, along with 82,000+ birds, 26,000+ marine mammals and untold numbers of other creatures, were impacted by the Gulf Oil Spill. It is impossible to determine how many other turtles were killed as a result of fires that were set in order to burn off surface oil (the Center for Biological Diversity sued to force a change in that strategy, please see article below).
