Did You Know?
Most starfish have a spiky or leathery surface, depending upon the species. The crown-of-thorns starfish is known for its thorny spines that are present all over its body. This tough covering on the upper side of the body acts as protection from its predators, as it is made up of calcium carbonate plates with tiny spines.
Amazingly, in case a starfish loses its arm, it is capable of regenerating the same in about a year! This is extremely useful when the sea star feels threatened by a predator, as it can lose the arm and escape. Sometimes, an entirely new starfish can grow from one arm. This phenomenon takes some time and occurs as most of the vital organs are stored in the arms.
These marine animals have a unique way of feeding on their prey. To be able to eat a prey that is larger than its mouth opening, the starfish wraps its arms strongly around the clams or shells, and then jerks it open. Then it pushes the stomach out into the shell and eats up the prey, and finally retracts the stomach back in through the mouth.
These facts about starfish tell us quite a story about the kind of life that exists beneath the sea. Complex, yet beautiful, life beneath the sea has a completely new world in store for us.
