Laura Cottongim 11/7/2007 1 Sea Turtle Conservation Lesson Plan Introductory Information Sea turtles are long-lived reptiles adapted to living in the world's oceans. There are seven species of sea turtles, five of which can be found off the coast in Florida's waters – these are the Green, Hawksbill, Kemp's Ridley, Leatherback and Loggerhead sea turtles. They all have evolved specializations to aid in their swimming lifestyles such as streamlined bodies and paddle-like flippers.
