The sea turtle makes its home in warm oceans around the world. This reptile is about 1 meter long for most kinds. Living there is not easy, but the sea turtle's body and habits are a good match for it.
One reason the sea turtle survives is flippers shaped like paddles, which push it through the water. (Flippers means flat limbs used for swimming.) It also has a smooth, streamlined shell, which helps water slide past as it swims.
The sea turtle is an omnivore, which means it is an animal that eats both plants and animals. Its food includes sea grass, jellyfish and crabs. To find food, it swims thousands of kilometers but returns to the beach where it hatched to lay its own eggs.
Young sea turtles are called hatchlings. Hatchlings dig out of the sand at night and race toward the bright, open ocean. The temperature of the sand decides whether the hatchlings will be male or female.
