Urban Herping – Finding Snakes in New York City

Bagging a snakeInspired by fellow Bronxite John Kiernan’s wonderful book A Natural History of New York City, I have searched for reptiles and amphibians in just about every corner of the Big Apple.  An amazing array of species manage to hold on here and in other cities around the world (Reticulated Pythons are regularly encountered in Singapore and Bangkok) – in fact, I cannot cover all of NYC’s species in a single article.  Today I’ll take a look at big city snakes.

Snakes of NY State

New York State is home to 17-18 species of snakes, most of which once dwelled within NYC limits. Three of these – the Copperhead, Timber Rattlesnake and Eastern Massasauga – are venomous.  Read More »

Turtles Seek Heat While Still in the Egg…Do They Also Choose Their Sex?!

Pelodiscus sinensisTurtles and other reptiles are full of surprises when it comes to reproduction.  In the past few decades we’ve learned that incubation temperature, not genetics, determines the sex of many species, that some have dispensed entirely with males (i.e. the Brahminy Blind Snake) and that the massive Komodo Dragon is capable of reproducing without fertilization.  Recently (May, 2011), biologists have determined that turtle embryos move within the egg and actively seek heat.  This finding may cause us to re-examine conservation techniques, and raises an array of important questions – i.e., can turtle embryos actually determine what sex they will be?

Amphibian News – Rare Frogs Breed in Captivity, Lost Species Found

Haitian LandscapeFrogs and frog enthusiasts have much to celebrate these days.  The endangered Lake Titicaca Frog, Telmatobius culeus, has reproduced in captivity, and 6 Haitian frogs, lost to science for decades, have been found.

Lake Titicaca’s Aquatic Giant

The huge, skin-breathing, cold-adapted Lake Titicaca Frog ranks as one of the world’s strangest amphibians.  Known only from this lake, which straddles the Peru-Bolivia border at 12,500 feet above sea level, the unique creature is threatened by the food trade and pollution.

I had the good fortune to work with what was, at the time, the only Lake Titicaca Frogs in captivity.  Despite nearly 2 decades of trials, I and my co-workers failed to raise the few tadpoles that were produced (please see article below).  However, Peru’s Huachipa Zoo, in association with the Denver Zoo, has announced that 5 apparently healthy tadpoles are now being reared.  A museum in Bolivia has been successful in breeding a close relative, the equally-rare Water Frog, Telmatobius hintoni.

2010’s Reptile Discoveries – New Lizard Species and Facts

Lacerta viviparaSeveral newly-discovered lizards and unexpected lizard facts made herp headlines in 2010.  From a female-only species to a 6-foot-long, brightly-colored new monitor, each gave us pause to wonder…”what’s next?!

Two Large Monitors

Undiscovered animals tend to be small and non-descript, but not so with Asia’s new contributions to the lizard role call.   The Northern Sierra Madre Forest Monitor, Varanus bitatawa, described last year from northern Luzon in the Philippines,is both large – to 6 feet in length – and colorful.  Actually, it remained undetected only to herpetologists…local people have been eating it for quite some time.  The newly described giant is arboreal and feeds largely upon fruit.

Paradise and Ornate Flying Snakes – New Research and Notes on Captive Care

Flying snakeOf all the gliding animals, Flying Snakes (Genus Chrysopelia) appear to me to be the most unlikely…they just don’t seem suited to moving through the air.  Yet they do, and quite well – not matching the abilities of flying squirrels, but certainly right up there with gliding geckos and frogs.  A recent study shed some light on their unique abilities, and suggests that they may serve as models for small, agile flying vehicles.
