The Race to Save the Sea Turtles
The Gulf of Mexico is home to five species of sea turtles, all of which are either endangered or threatened, including the Kemp's ridley, considered to be the most endangered sea turtle in the world with only about 3,000 in existence. Kemp's ridleys have almost circular shells, grow to about 2 feet long, and weigh about 100 pounds. Adults are olive green on top and yellow below, and their main food source is crabs. Their main nesting area historically is along a 16-mile stretch of beach at Playa de Rancho Nuevo in Tamaulipas, Mexico, and although females lay about 100 eggs at a time, only about 1% of the hatchlings survive to adulthood.
In the 1970s, an international effort was begun to establish a second nesting area at Padre Island National Seashore, using the theory that sea turtles always return to the beach where they were hatched to lay their eggs. More than 22,000 eggs were gathered from Playa de Rancho Nuevo between 1978 and 1988, placed in boxes containing Padre Island sand, and shipped to Texas, where they were placed in incubators. After hatching, about 13,500 baby turtles were released on the beach at Padre Island National Seashore and allowed to crawl into the water for a quick swim. Fearing that the young turtles would become lunch for predators, National Park Service biologists captured them and sent them to a marine fisheries lab in Galveston, where they spent up to a year growing big enough to have a better chance of survival in the wild. They were then tagged and released into the Gulf of Mexico.
Since then some of the turtles have returned to Padre Island and other sections of the Texas Gulf Coast to nest, and Park Service workers have collected a number of eggs for incubation and eventual release. The eggs are collected in late spring and summer, and anyone seeing a nesting sea turtle is asked to not disturb it but to report its location to national seashore personnel. The public can attend releases of the hatchlings, which usually occur in June and August; for information on release dates, call the Hatchling Hotline at tel. 361/949-7163.
