Starfish

---

Starfish are more correctly known as sea stars as they are only very distantly related to fish, theyare marine invertebrates belonging to phylum Echinodermata, class Asteroidea. The names sea star and starfish are also used for the closely related brittle stars, which make up the class Ophiuroidea. Starfish typically have five or more "arms" which radiatefrom their centers. Starfish do not rely on a jointed, movable skeleton for support and locomotion but instead possess a hydraulic water vascular system that aids in locomotion. There are about 1,800 known living species of starfish, and they occur in all of the Earth's oceans
