Habitat
Sea stars can be found in rocky shores, tide pools, dock pilings and bay bottoms.
Diet
Sea stars are carnivores, which means they eat meat. They eat clams, oysters and mollusks. Sea stars eat by pushing their stomachs through their mouths, which are located in the center of the animal. One star might eat a few dozen small clams in a week. Sea stars grow bigger the more they eat, so a large sea star means that it gets a lot to eat.
Movement
Sea stars use their tube feet to move. They pull sea water into their bodies through their stomachs to help their tube feet suck onto things to help pull them forward.
Description
Sea stars are also known as starfish because they are shaped like a star. They appear in many colors, including shades of brown, red and orange that act as camouflage. Their coloring and their tough, hard outside can keep away predators.
Enemies
Enemies of the sea star include crabs, fish and birds, as well as humans, who compete with the sea stars to harvest shellfish.
