American Box Turtles as Pets – Care and Natural History

Male Eastern Box TurtleThe beautifully-patterned American Box Turtles (Terrapene spp.) are very popular among reptile enthusiasts worldwide. They are extremely responsive, intelligent, calm, and may live for 60-100 years…what more could a turtle fan want!  Unfortunately, there are many misconceptions concerning their care.  The following information will enable you to meet their needs…please post any specific questions you may have.

Note: Box Turtle populations have declined drastically. In addition to habitat loss and road-kill, many were exported to foreign pet markets when European tortoises were protected by law.  Please purchase only captive-bred animals.

Natural History

Four Box Turtle species the Eastern, Spotted, Ornate and Coahuilan – range from southern Canada through most of the USA and into Mexico.  Ten uniquely-colored subspecies, including the Florida, Gulf Coast and Yucatan Box Turtles, are also recognized.

Box Turtles frequent woodlands, marshes, fields, agricultural land, and many other habitats.  Some, such as the Eastern Box Turtle (T. carolina), are largely terrestrial, while Three-Toed Box Turtles (T. carolina triunguis) and others split their time between land and shallow water.  The Coahuilan Box Turtle (T. coahuila), the group’s only truly aquatic member, is found only in Mexico’s Cuatro Cienegas Basin.  Several of my colleagues at the Bronx Zoo studied this species in the wild, and I had the good fortune to work with a breeding group for many years; please look for my future article on this most unique turtle.

Although certain other turtles posses shell hinges that allow the plastron (lower shell) to be drawn up (“like a box”), in no group is this ability so well developed as the American Box Turtles (please see photo). Read More »

Green Sea Turtles Die on Farm – Do Meat-Trade Turtles Aid Conservation?

Green Sea TurtleAn accident that caused the deaths of 299 endangered Green Turtles at the Cayman Turtle Farm has raised concerns about the facility’s operation. The incident brought other issues to my mind as well.  I was first inspired by the legendary herpetologist Archie Carr, and have since been involved in several field studies of Green, Leatherback and other marine turtles (please see article below).  I see the value in organizations such as Cayman Turtle Farm, which raises turtles for the food market while also racking up important “firsts” in breeding and research.  However, many disagree with me.  What’s your opinion?  Any comments you may wish to post below would be much appreciated.

Conservation through Commercialization

Whatever your personal feelings concerning the consumption of turtles or other animals may be, it is clear that commercial farming can play a role in Chinese Softshellconservation. The classic US example is the American Alligator.  Legal protections helped, of course, but large scale breeding for the meat and hide trade made a huge difference in that species’ future.  Read More »

Reptile & Amphibian Conservation – Protection Sought for 53 US Natives

San Bernardino Ringneck SnakeI’ve recently posted information concerning a petition that seeks Endangered Species Act protection for 53 US herps.  Many readers applauded the news, but some were concerned about potential limitations on their ability to keep protected species.  As they correctly pointed out, responsible pet owners have made important contributions to the conservation of many species (please see article below).  In the course of my work as a zoologist, I’ve often dealt with federal, state and international permits, and continue to assist zoos with related issues.  Today I’d like to explain a bit more about this proposal, which was championed by the Center for Biological Diversity, and how it may impact target species in the wild and captivity.

The ESA: Pros and Cons for Herp Keepers

Although federal red tape complicates life for private herp owners, the Endangered Species Act (ESA) remains our nation’s most powerful conservation tool.  A recent study revealed that the ESA is 99% effective in preventing extinctions…once a species is listed, its survival is almost guaranteed.  Benefits to such species extend beyond permit requirements – habitat protection, research funds, compilation of recovery plans and other possibilities arise.  This post lists frequently asked questions concerning the ESA.

Reptile and Amphibian Conservation in the USA – 2012 Update

The global extinction crisis faced by amphibians has been much in the news in recent years, as have threats to sea turtles, Madagascar’s tortoises, Asia’s freshwater turtles and other long-suffering groups.  In the USA, a number of reptile and amphibian species are also in dire straits despite, in some cases, federal protection.  I hope this article inspires both hope and action in my many conservation-minded readers.

Unprecedented Agreement May Help 757 Species

Following a slew of lawsuits by the Center for Biological Diversity (CBD), the Federal government has agreed to speedily consider protecting an additional 757 native species under the Endangered Species Act (ESA).  The CDB employs an attorney who deals solely with amphibians and reptiles, and the agreement is said to be “airtight” and legally enforceable.

This agreement is an important step, as the ESA is our most powerful wildlife law.  Indeed, ESA listings have proven vital to the continued survival of many species.  For example, a recent CBD study of 110 ESA-protected species showed that 90% of them were recovering “on time”, according to the goals set at the original listing…not bad, considering what is happening to rhinos and other “protected” species elsewhere!

“Salt Water” Snapping Turtles – Snappers and other Turtles in Estuaries

55 lb. Snapping turtleThe incredible diversity of life in tidal creeks and rivers has attracted me since childhood.  And while invertebrates and fishes predominate, areas where fresh and salt water meet hold wonderful surprises for reptile enthusiasts as well.  Today I’d like to discuss a turtle that I often find in brackish water habitats, and which seems to be evolving unique adaptations to survive there – the Snapping Turtle, Chelydra serpentina.

A Turtle Banquet

The Long Island (NY) tidal creeks (please see photo) that I frequent seem “paved” with crabs, marine worms, snails, bottom fishes, mussels, clams, shrimp and other foods that could be easily exploited by turtles.  In fact, research indicates that at least one marine turtle, the Kemp’s Ridley, actively migrates to the LI Sound, gaining up to a pound per week during the time it remains there.  The Snapping Turtles I’ve seen in such habitats have been quite large, and I can’t help but think that abundance of high quality, easily-caught food must play a role in their presence.

I’ve even been fortunate enough to come upon a family of River Otters in one tidal creek, a species long gone from LI but now making a comeback.  I’ve worked with captive otters, and can attest that if they are present, there’s lots of food about – their appetites are unbelievable! Read More »
