Hello, Frank Indiviglio here.  As a bug-hunting child, I was once startled to come upon a housefly that appeared to be walking on its hind legs.  Closer inspection revealed that the unfortunate insect was being carried in a head-up position by a Jumping Spider.  I was aware that a variety of these brilliantly-colored little beasts inhabited my Bronx neighborhood, and became interested in how they managed to capture such elusive prey without a web. I began reading and collecting, and was soon fascinated by their keen eyesight and cat-like stalking techniques.  They would follow my finger, leap on a feathers pulled by a string, and even display to a mirrors. 

I’ve recently learned that biologists are showing videos to Jumping Spiders in an attempt to learn more about their remarkable eyes (which allow for forward, backward, an sideways vision simultaneously), and that a new ant-mimicking Jumping Spider with enormous fangs has turned up in Borneo.  I’ll highlight this new information below, and review their natural history and captive care. 

A 360 Degree Field of Vision

Animals that are on the menus of other creatures generally have eyes set well back and to the sides of their heads.  This arrangement gives mice, deer and others a wide field of vision, with the only bind spots being well to their rear.  Predators, such as foxes and hawks, usually have forward-facing eyes, to allow for accurate focusing on prey.

Hello, Frank Indiviglio here.  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 »

Hello, Frank Indiviglio here.  Unfortunately, animal abuse is a serious and surprisingly common problem in the USA. The applicable laws vary from state to state, and it can be difficult to determine which agency is responsible for enforcement. Regulatory agencies are often under-funded, so many rely upon citizen complaints. It is important, therefore, that concerned people learn how to proceed when they suspect that animal abuse is taking place. This is especially true where reptiles and amphibians are concerned, as they draw less interest than mammals, and mistreatment is difficult to detect by the inexperienced.  Please be sure to post your own observations below, and let me know if you need help in deciding how to report a problem.

State Law

Animal abuse is a crime every state in the USA, and most aspects of the problem are controlled by state law. This results in a confusing array of widely differing statutes and enforcement policies. Details, such as what constitutes abuse and how the laws are actually enforced, vary from state to state. Until recently (July, 2012), for example, an Indiana “festival” that allowed participants to twist off the heads of turtles for public amusement was held not to violate state law (please see below)!  In some states, live Tiger Salamander larvae are legally used as fish bait (please see this article), while in others they are protected as an endangered species.

Hello, Frank Indiviglio here.  An 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 conservation. 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 »

Hello, Frank Indiviglio here.  The Argentine or Ornate Horned Frog (Ceratophrys ornata) may be the world’s most popular amphibian pet.  Dubbed the “Pac Man Frog” due to a resemblance to the large-mouthed video game character, it is beautifully colored and “charmingly” pugnacious in disposition.  Despite their size (females may be compared to salad bowls; males are much smaller), Horned Frogs require relatively little space and are an ideal choice for those seeking an interesting pet that may live to age 20 or more.  Albinos and other unique color morphs, as well as hybrids between related species, are available.

Natural History

Argentine Horned Frogs inhabit savannas (grasslands) in Argentina, Uruguay and Brazil. In some regions, they become dormant during cool, dry periods.

Seven related species have been described.  Of these, the Cranwell’s or Chaco Horned Frog (Ceratophrys cranwelli) is most frequently seen in the pet trade.  The following information can be applied to its care.  The Surinam Horned Frog (C. cornuta) bears the longest “horns” of all (please see photo).  Read More »
