Starfish



The bottom of the Starfish is in middle of its body on the top part. The mouth however, is placed in exactly the same place, just on the bottom. They are boneless creatures that live underwater, which makes them marine invertebrates. They eat oysters and other molluscs. Most species are 20cm long, (200mm) and there are 1,500 known species so thats a lot! They have an internal Skeleton which is made from hard bony plates that are called ossicles.
