Animals that have shells-
A shell is an hard exterior or exoskeleton that can be used as a protective measure for a lot of animals without a vertebrae. There are many animals that have shells, and they’re found on both land and sea. The shells are composed of calcium carbonate and a little amount of protein. The animals with shells often use it as their home too, sometimes making it impossible for predators to prey on them.
Why Do Animals Need Shells?
Although we think of an animal’s shell as a portable house, it is more than that. Shells serve several purposes. A shell can help an animal:
*-Hide from predators.
*-Protect its inner organs.
*-Get shelter from the rain, wind and sun.
*-Navigate safely in its environment.
Each animal species uses shells differently.
Armadillos need their thick armor to burrow deep into the sand, which is where they build their nests and hide from predators.
The shells of mollusks cover these animals completely to protect their soft bodies as they tumble around the ocean floor. Crabs and lobsters allow plants and algae to form on their shells as camouflage.
Scales Are Not Shells
Some animals have scaly hides. They include fish, alligators, and snakes. While scales are also protective, they are not the same as shells. Their chief function is to keep water inside the animal’s body. Scales also help animals move smoothly through the water or on land.
