Leatherback Sea Turtle
LEATHERBACK (Dermochelys coriacea) The leatherback is a fascinating and unique animal, even among sea turtles. It is larger, dives deeper, travels farther, and tolerates colder waters than any other sea turtle. Most leatherbacks average 6 feet in length and weigh from 500 to 1,500 pounds, but the largest leatherback on record was nearly 10 feet long and weighed more than 2,000 pounds. Leatherbacks look distinctively different from other sea turtles. Instead of a shell covered with scales or shields, leatherbacks are covered with a firm, leathery skin and have seven ridges running lengthwise down their backs. They are usually black with white, pink, and blue splotches and have no claws on their flippers. Leatherbacks eat soft-bodied animals such as jellyfish, and their throat cavity and scissor-like jaws are lined with stiff spines that aid in swallowing this soft and slippery prey. Young leatherbacks in captivity can consume twice their weight in jellyfish daily. True denizens of the deep, leatherbacks are capable of descending more than 3,000 feet and of traveling more than 3,000 miles from their nesting beach. They are found throughout the Atlantic, Pacific, and Indian oceans, as far north as Alaska and Labrador. Researchers have found that leatherbacks are able to regulate their body temperature so that they can survive in cold waters. The leatherback is found in Florida's coastal waters and a small number (from 30 to 60 a year) nest in the state.
