The term 'star fish' is a common name for the species of echinoderms known as Asteroidea. These animals are characterized by their star-shaped bodies and five or more arms. The scientific name for this species is PISCES, which is a six letter word. Starfish are found in all oceans and can range in size from a few millimeters to over a meter in diameter. They feed on mollusks, worms, and other small organisms. Starfish play an important role in the marine ecosystem, helping to keep the ocean floor clean by consuming detritus and other organic matter.
