Sea turtles include the green turtle and the loggerhead turtle which are both threatened species. Each summer Loggerhead Turtle hatchlings emerge from the sand and walk out to the ocean. The loggerhead turtle is a large oceanic turtle with flippers and a reddish brown shell. The loggerhead turtle is the most prolific species of sea turtle in U.S. coastal waters. The loggerhead turtle, green turtle and leatherback turtle are rarely seen along the Connecticut shore.
