Interesting Facts About Pretty Starfish

Are you always impressed when you see pretty starfish? But do you know anything about them? Starfish belong to a group of marine animals called echinoderms and they are not actually fish. Starfish are known as sea stars as well, which is a more logical name for them. Sea stars live in all oceans around the world and the largest population of them can be found in the Indian and Pacific Oceans. They are mostly located in the shallow water or on the cold seafloor, they don’t move too much. Sea stars have a specific shape of the body, they have a central disc and five or more arms. That explains why are they called starfish or sea stars since they live in the water and they look like a star.

Amazingly, sea stars have very interesting features which make them special and different from the other marine animals. For example, they have unusual feeding, they eat with their stomach inside-out. Sea stars have eyes on each arm and they don’t see colors, they can reproduce sexually and asexually by regeneration and losing one arm. The most interesting thing about sea stars is that they have no brain nor blood and they cannot survive in freshwater. Starfishes move using their tube feet, which are filled with seawater and they can move quicker than you might expect.
