Natural Habitat: The natural habitat of starfish spans right from the intertidal zone, i.e., the seashore which is exposed to the air during the low tide and goes underwater during the high tide, to the abyssal zone, which has a depth of roughly about 4000 - 6000 meters.
The Asteroidea occupy several significant ecological roles. Starfish, such as the ochre sea star (Pisaster ochraceus) and the reef sea star (Stichaster australis), have become widely known as examples of the keystone species concept in ecology.s well as the starfish, the echinoderms include sea urchins, sand dollars, brittle and basket stars, sea cucumbers and crinoids. The larvae of echinoderms have bilateral symmetry, but during metamorphosis this is replaced with radial symmetry, typically pentameric.
