Newts as Pets – an Introduction to their Care and Feeding

Eastern NewtAlthough my interests are wide, newts and salamanders have always held a special fascination for me.  Beginning in childhood, I sought to keep and breed as many species as possible, and I focused on their husbandry and conservation when I entered the zoo field.  In time, I wrote a book summarizing my experiences (please see below).  The passage of so many years has not dulled my enthusiasm for these fascinating amphibians, and I can highly recommend them to both beginning and advanced herp keepers.

The following information may be applied to the care of Japanese Fire-Bellied, Eastern, California, Ribbed and Paddle-Tailed Newts, as well as most others that appear in the pet trade.  Please write in for detailed information on individual species.

Newts as Pets

An ability to thrive on commercial pellets distinguishes newts from other amphibians, and endears them to folks who prefer not to handle live insects.  All are brilliantly-colored, active by day, and usually live well in groups at average room temperatures.  Most become quite tame over time, and will even accept food from your hand.  Several California Newts in my collection have lived to age 20, and others seem bent on exceeding that.

Frog Communication – Study Shows Frogs go far Beyond Croaking

Rana adenopleuraA recent study has challenged what we know, or thought we knew, about frog communication.  Researchers were astonished to discover that the calls of male Emei Music Frogs, (Babina daunchina) inform females of such details as the length and width of the singer’s burrow.

Construction Skills Needed

Named for the males’ banjo-like calls (they really do sound like banjos, please check video below), the Emei Music Frog is native to marshy habitats in central and southwestern China.  Females deposit their eggs in burrows constructed by the males, and the tadpoles develop there as well.  The ability to construct a safe burrow is, therefore, an important consideration when females go “mate shopping”.  You can see photos of the unique nests and egg masses of a related species, Japan’s Ryuku Brown Frog, here.

A Sub-Surface Basking Site and Shelter for Semi-Aquatic for Turtles, Newts and Frogs

Basking Yellow-bellied SliderI’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.

World’s Smallest Frogs Added to 2011’s List of Newly-Discovered Amphibians

Eleutherodactylus iberia
Two frog species recently discovered in southeastern New Guinea are smaller than any other 4-legged vertebrate.  Within their pea-sized bodies, they pack a brain, lungs, heart, digestive system and most of the other organs that people have…simply astounding!

Tiny Frogs and Fish

The frogs, Paedophryne dekot and P. verrucosa, were collected several years ago, but were only described as new species this year (please see ZooKeys article).  Among all the world’s vertebrates, only a single fish, a Southeast Asian relative of the carp (see amazing photo here) is smaller – and the new frogs exceed it in size by only 0.1 mm!  Another contender for the title, a leaf-litter frog from Cuba (please see photo of striped frog), is only a tiny bit larger.

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.
