The Mysterious Starfish
Did You Know...?
Starfish, sea animals that are not fish-like at all, are truly mysterious creatures. There is a movement to stop calling them "starfish" and to start calling them "sea stars." Starfish looks like star-shaped coral, thus a boney and spiny exterior. They are known to regenerate their limbs when broken.
The main diet of starfish are shellfish such as clams, snails, oysters, hermit crabs, and other mollusks. Starfish have suctioning tube feet to pry open shellfish, then the stomach extrudes from the mouth to feed on the prey by injecting digestive juice into the prey such a clam and then the stomach sucks the prey into the two-chamber stomach.
