Lesson Plan – Sea Turtle Life Cycle Summary This lesson explains the life cycle of sea turtles focusing on specific aspects of the loggerhead sea turtle life cycle. The Southeastern U.S. has the largest nesting aggregation of loggerhead sea turtles. Sea turtles are also charismatic megafauna that highlight many of the harmful environmental impacts that affect sea life. This lesson will address how these environmental impacts have been addressed through actions of concerned citizens and public policy. Content Area Marine Biology, Environmental Policy Grade Level 3-5 Key Concept(s) Sea turtles are a great case study to examine how we must look at the entire life cycle of an animal to fully understand how to protect it. Loggerhead sea turtles nest on beaches in the southeastern U.S., travel thousands of miles and spend a lot of time in open ocean waters throughout their development and maturity, and feed in shallow nearshore waters.

Turtle Trivia

•  Florida beaches are home to 80% of Loggerhead turtles in the U.S. •  Turtles can migrate thousands of miles, but usually return to lay their eggs on the same beach

where they hatched •  Sea turtles have existed for over one hundred million years •  Sea turtles are reptiles. They breathe air, and can hold their breath for long periods of time. •  When its time to sleep, a loggerhead will wedge under a rock close to the shore, or take a snooze

while floating on the surface of deep water •  Hatchlings weigh less than one ounce and are only two inches long. Adults can grow over 3 feet

long and weigh 200 to 300 pounds! •  The nest temperature during incubation determines a sea turtle's sex. Boys like it cool - Girls like it

hot. •  Sea turtles have great underwater vision, but are nearsighted out of the water. •  Although sea turtles do not have external ears, they are capable of hearing low frequency sounds

and vibrations •  Sea turtles use their strong jaws to crush a diet of crabs, shrimp, mussels, and jelly fish.
