The St. Lucia Racer or Ornate Ground Snake, Liophis ornatus, has the unenviable distinctions of being both the world’s rarest snake and the species with the smallest range…it may even be the rarest creature on the planet.  The entire population – 11 individuals at last count – is confined to a 30 acre Caribbean island off St. Lucia.

Ever since reading Archie Carr’s wonderful books as a child, I’ve been drawn to the Caribbean’s islands and coastlines.  As luck would have it, I eventually found myself working at Tortuguero, Costa Rica – the very site where much of his ground-breaking Green Turtle research was done.  There I became hooked on the region’s fantastic array of creatures, and endeavored to become familiar with as many as possible.  In time, I tagged Leatherback Sea Turtles on St. Croix, collected Bahaman Brown Racers, Alsophis vudii, on several islands, and vowed to find again a large, flying Mole Cricket that once stopped me in my tracks on St. Lucia.  Unfortunately, Caribbean animals suffer some of the world’s highest extinction rates.  In fact, the St. Lucia racer was “officially extinct” for nearly 40 years.  Happily, we now know that it still holds on…but just barely.

In 2010, I highlighted a study that documented steep declines in a number of snake species.  Despite disturbing similarities to the “Disappearing Amphibian Crisis”, the snake situation seems not to have generated widespread concern.  In my own career as a herpetologist, opportunities to become involved in snake conservation were also limited. Although I was fortunate enough to work in programs designed to bolster the populations of several species, including Green Anacondas, Indigo and Hognose Snakes, most such efforts were short-lived.  I was pleased to learn, therefore, that a partnership of several major conservation organizations has made the plight of the world’s snakes a priority for the year 2013.

The Year of the Snake…your input needed

The Year of the Snake effort is spearheaded by Partners in Amphibian and Reptile Conservation, and was preceded the Year of the Turtle and the Year of the Lizard.  PARC will be joined by the Center for Conservation Biology, the Orianne Society and other notables (please click here for a complete list).  In addition to field research and captive breeding programs, public education will be a major component of each group’s activities.  I was very glad to see that input from interested non-professionals will be solicited.  This is an all-too-rare step, despite the fact that professionals, being limited in both numbers and financial resources, cannot begin to address the myriad conservation needs of the world’s threatened snakes.  Please see “What Can I Do”?, below, if you wish to participate.

An amazing array of newly-discovered reptiles and amphibians grabbed our attention this past year.  The unexpected discoveries of an undescribed Leopard Frog in New York City and a Rainbow Skink in an Australian backyard reminded us that wonderful surprises surround us, if only we take the time to look and learn.  Frogs that dye human skin yellow, snakes that specialize in eating only eggs or snails, iridescent skinks sporting tails twice their body length…the list is simply astounding.  Today I’ll highlight a few that have especially captivated me; please post your own favorites (whether covered here or not) below.

Australian Rainbow Skinks

2012 was designated as the Year of the Lizard by several conservation organizations, so I’ll lead off with 3 new skinks that turned up in Queensland, Australia.  The brilliant colors of breeding males lend these tropical lizards their common names (please see article below).

The Elegant Rainbow Skink, Carlia decorata, was well known to folks in Townsville, Queensland, as a common garden resident. Upon taking a closer look, however, herpetologists realized that the colorful creature was an undescribed species. Read More »

Mauritius, an island nation off the coast of southeast Africa, is best known to naturalists as the site of the Dodo Bird’s extinction (Mauritius also is, in a sense, the reason I was hired by the Bronx Zoo and spared life as a lawyer – see article below for the story!).  Herp enthusiasts, however, know it as the habitat of several unique reptiles, all of which are now very rare or extinct. But we can delight in some news just released by the Durrell Wildlife Trust – a new population of the Round Island or Keel-scaled Boas, Casarea dussumieri, will soon be established in the wild.  This unusual snake disappeared from nearly all of its range in the 1860’s, and its return is the culmination of 40 years’ worth of captive breeding and habitat restoration efforts.

Status and Conservation

The Round Island Boa is now confined to Round Island, a tiny speck of habitat where perhaps 500-1,000 individuals survive.  A single wild population and limited number of captives place it at continued risk of extinction.  The new population to be established on another Mauritian island (where the snake formerly lived) is a vital step towards ensuring the species’ survival.  Read More »

While working at the Bronx Zoo, I had the once-in-a lifetime opportunity of helping to import and care for one of the largest snakes in captivity.  While “largest snake” debates are ongoing, the massive Reticulated Python I came to know was awe-inspiring by any standard.  Dubbed “Samantha”, she was captured as an adult in Borneo, and eventually reached 26 feet in length and 275 pounds in weight.  The story of how she arrived in the USA involves a cash reward established by Theodore Roosevelt, the leather trade, animal dealers and other twists and turns.

Wanted: 30 Foot-Long-Snake

In 1910, Theodore Roosevelt, long involved with the Bronx Zoo, offered a reward to the first person who presented a snake of 30 feet in length; in time the reward grew to $50,000.  In 1992, I and other Bronx Zoo staff heard rumors that a giant Reticulated Python that had been captured in Borneo.  We did not get overly-excited… being well-seasoned, I automatically deducted 25-50% from the size of any “biggest snake-turtle-croc” stories that came my way.  But then grainy photos arrived by mail, and the snake depicted was, if not the largest I’d seen, impressive.  Whether by design or bad luck, the photos did not allow us to accurately gauge the animal’s length.
