A starfish is shaped like a star. If it looses a leg or an arm it will grow another one. A starfish has a red eye at the tip of each arm. The starfish's arm will send water to many little tube feet underneath. While the water is pumped out, each "foot" becomes a tiny suction cup. A starfish has a fish in its' name but it not a fish. A starfish east clams, starfishes and almost any small creatures.
