Sea Turtle Species

There are only 7 Sea turtle species in existence with most of them being on the verge of extinction. These are some of the largest turtles on our planet. They spend their wholes lives out in the open oceans and only come on to land to lay their eggs.

Sea turtles are reptiles and require air to breathe. Their lifespan is estimated to be around 80 years old.

Some of the threats that endanger a sea turtle’s life are natural predators like raccoons, birds, crabs, and ants. They will either eat the sea turtle eggs or eat the hatchlings as they try to venture to the open sea.
