Often caught in fishing gear, and wanted for their eggs, meat, oil, and shell, green sea turtles are listed on the Endangered Species Act. Breeding populations found in Florida and on the Pacific coast of Mexico are listed as endangered; the green sea turtle is listed as threatened in all other areas where it is found.
