Is a starfish a fish?
Sea stars, commonly called, “starfish,” are not fish.
They do not have gills, scales, or fins. Sea stars live only in saltwater. Sea water, instead of blood, is actually used to pump nutrients through their bodies via a ‘water vascular system.
Many different animals eat sea stars, including fish, sea turtles, snails, crabs, shrimp, otters, birds and even other sea stars. Though the sea star’s skin is hard and bumpy, a predator can eat it whole if its mouth is large enough. Predators with smaller mouths can flip the sea star over and eat the softer underside.
A typical starfish has five-sided symmetry. With no clear head, the starfish can move in any direction, led by any one of its five arms.
