Sharks & Rays

Sharks and rays belong to an ancient group of fish whose skeletons are composed entirely of cartilage. There are several hundred species of sharks, ranging in size from six inches to over 50 feet; the very largest ones - whale sharks and basking sharks, are plankton-feeders. Only about a dozen or so species have actually been implicated in unprovoked attacks on human beings. These attacks are extremely rare, and can often be attributed to mistaken identity. Today, most of the larger species are declining in numbers, due to overfishing.
