The seven existing species of sea turtles are the green sea turtle, loggerhead sea turtle, Kemp’s ridley sea turtle, olive ridley sea turtle, hawksbill sea turtle, flatback sea turtle, and leatherback sea turtle.
All six of the sea turtle species present in U. S waters (Loggerhead, Green sea turtle, Hawksbill, Kemps Ridley, Olive Ridley, and Leatherback) are listed as endangered and/or threatened under the Endangered Species Act. The seventh sea turtle species is the Flatback, which exists in the waters of Australia, Papua New Guinea and Indonesia. Sea turtles can be separated into the categories of hard-shelled (cheloniid) and leathery-shelled (dermochelyid). There is only one dermochelyid species which is the leatherback sea turtle.
