Sea Turtles

Sea turtles are vertabrates of the Sandy Beach. They can grow up to 5ft long and range from 150-400 lbs. Sea Turtles start as a carnivorous animal eating crabs, mollusk, and shrimp, but as they mature they become herbivores. Unlike a regular turtle, a Sea Turtle cannot retract its head or flippers which make them vulnerable on land. Because of their vulnerability they usually only come on land, during the warmest months of the year, to nest. They nest during high tide using the front flippers to dig a nest that they then lay the eggs in. They will nest at the same beach each year.

Geological Interaction: Seaturtles usually stay in the water, but they use the beaches to nest.

Physical Interaction: Sea turtles use the high tides at night to come onshore to create nests and lay thier eggs.
