Sea turtles, a marine reptile, are one of the planet's most ancient creatures, having been around since the time when dinosaurs roamed - over 110 million years ago. Today, seven different species of sea turtles live throughout the world with each species classified as either threatened or endangered. Of these, five species of sea turtles call Florida's waters home and three species; the loggerhead sea turtle (Caretta caretta), the green sea turtle (Chelonia mydas), and the leatherback sea turtle (Dermochelys coriacea) nest annually on Broward County's beaches from April through September. Loggerhead sea turtle nests are the most commonly found in the area, historically accounting for over 90% of all sea turtle nests in Broward County. In fact, the beaches from the Space Coast to the Gold Coast of Florida represent the second most important nesting area in the world for loggerhead sea turtles.
