Turtles

(General Classification)

    Turtles are reptiles and cold-blooded. They depend on their surroundings for their body heat.

(Description)

    Turtles are covered with a hard box-like shell which protects the soft body and organs. It is composed of an upper section called a carapace and a lower plate called a plaston. The head, tail, and legs of turtles are covered with scales. Turtles withdraw them inside the shell for protection. Turtles have four paddle-shaped flippers which help them swim. Turtles do not have teeth, they have a sharp beak instead.

    Turtles can breathe on land and underwater. They mainly eat jellyfish, sea snails, and other soft-bodied, slow-moving sea animals.

    Female turtles lay their eggs in the sand on beaches. Once the eggs are covered the female returns to the sea. When the eggs hatch, the baby turtles crawl down to the sea and take care of themselves.
