water, but
young turtles
sometimes spend their summers
eating and growing in
New England waters.
Size Average 300-350 pounds and up to 4 feet long
Diet Adult green sea turtles eat mostly plant matter,
but
younger
turtles also
eat squids, crabs and other small sea creatures.
Lifespan Possibly 100 years or more
Range Tropical to temperate waters worldwide
Habitat Adult green sea turtles prefer coral reefs, sea grass beds
and mangroves,
while hatchlings and juveniles live farther from shore.
Predators Foxes, weasels, cats, dogs, raccoons, crabs and more eat
eggs and
hatchlings. Sharks and other large fishes prey on juveniles and adults.
Relatives There are seven species of sea turtles, including the green,
loggerhead,
Kemp’s ridley, olive ridley, hawksbill, flat back and leatherback.
Family life Females bury clutches of approximately 100 eggs on tropical or subtropical beaches. Once the eggs are buried, the females return to the sea. The eggs hatch after several months, and the hatchlings race for the sea before they can be eaten by crabs or sea gulls. It can take more than 20 years for sea turtles to reach breeding age.
Conservation status Endangered Green sea turtles are endangered, which means they are facing a very high risk of extinction in the wild. They are threatened by accidental catch, habitat loss and water pollution.

Blue Lifestyle tips
You can make a difference by avoiding chemical pesticides and fertilizers. Even if you live far from shore, these chemicals will make it to the sea. Help save sea turtles by choosing organic.
