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

Early spring is a favorite time for amphibian enthusiasts. Here in the northeastern USA, a spectacular event is unfolding, as Wood Frogs, Tiger and Spotted Salamanders, Spring Peepers and others head en masse for their breeding ponds. I’ve been visiting one pond, first shown to me by herpetologist John Behler, for nearly 30 years.  When luck is with me, I can see 3 amphibian species, along with fairy shrimp and other interesting creatures, in a single evening (please see article below).

The small vernal (temporary) pools used by many amphibians are fragile habitats, and quickly spoiled by pollutants; that many are near roads worsens the situation.  With their highly-permeable skins, amphibians are especially sensitive to changes in water quality.  The recent finding that Spotted Salamanders (Ambystoma maculatum) may be evolving defenses against roadside toxins is a rare light at the end of the rather dismal “amphibian conservation” tunnel.

New reptiles and amphibians turn up regularly, but, being generally small and inconspicuous, most excite only hard-core herp enthusiasts.  In recent days, however, a string of good-sized, colorful and totally unexpected discoveries have drawn attention from even “regular” people.  The new species include a spiny, brick-red skink, a sea snake with uniquely-raised scales, and a new family of hard-headed caecilians, those oddest of amphibians.

Western Pilbara Spiny-Tailed Skink (Ergenia cygnitos)

The beautiful, deep-red color of this spine-covered skink closely matches the rocks of its desert habitat in Western Australia’s Pilbara region.  You can see its photo and learn more in the article linked below.

Over the past 12 months, 9 other new species – 7 reptiles and 2 frogs – have been found in the same area.  Several related skinks (please see photo) and a “barking” gecko are included among the newly-described creatures.  Mining proposals spurred the surveys in Pilbara.  Hopefully, the discovery so many previously unknown species will limit commercial activities until further studies have been completed.

A 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 farm in southern Brazil’s pampas region has yielded the bones of an ancient mammal-like reptile loosely described as a terrifying cross between a Komodo dragon and a tiger.  Having worked with both of these modern-day predators, I was immediately intrigued by the newly-described creature (Proceedings of the National Academy of Sciences, Dec., 2011), dubbed the “Pampas Killer”.

A Reptile, but…

The Pampas Killer, or Pampaphoneus biccari, haunted Brazil’s grasslands during the Permian Period, some 260 million years ago.  It has been classified as a Dinocephalian Theraspid, or “Mammal-like reptile”.  Interestingly, today’s monitor lizards are also sometimes described as “mammal-like” by those familiar with them.

The Paleontologists (scientists who research ancient creatures and the history of life on earth) who are studying the Pampas Killer believe it possessed characteristics of both monitors and predatory mammals such as tigers – yikes!  It and related dinosaurs may have been an early step in the evolutionary march towards warm-blooded, furred mammals, which appeared 35 million years later.   Please see the drawings and articles below for artists’ re-creations of the Pampas Killer and its relatives.  Read More »

The subject of giant constrictor attacks upon people always brings out wild claims.  While working with Green Anacondas in Venezuela, I tried to track down 2 reports of human predation, but was unable to prove or disprove either.  I recall reading several well-authenticated accounts in old issues of Herpetologica, and sadly, have first-hand knowledge of a tragic incident involving a captive Burmese Python in NYC.  But a recent article on the Agta people of the Philippines took me very much by surprise – from 1939-1973, 26% of all Agta men, and 2% of the women, had been attacked by Reticulated Pythons!

Living with Giant Pythons

The article, published in a recent issue of The Proceedings of the National Academy of Science of the USA, was co-authored by a prominent herpetologist and a scientist who lived with the Agta people, in a remote region of the Philippines, for 24 years; some impressive photos are included as well (please see abstracts, below).  Read More »
