Outline: The Loggerhead Sea Turtle


The loggerhead sea turtle is the most studied of the seven sea turtle species. Although the knoledge on it is limited, it is an interesting animal. I look forward to catching a glimse of one in the bahamas. So I hope to teach the class about tutle habitat, range, and basic knoledge. Also, I hope to look at how humans influence the turtle.
