Bottom animals crawling with ambulacral legs, usually equipped with suckers. Everywhere live in the oceans and seas (except desalinated areas) to a depth of 8.5 km.
Most of the sea stars are predators, feeding mainly on mollusks and other invertebrates. Some eat plankton and detritus.
Having discovered the bivalve mollusk, the star of the sea grabs his shell with his hands, sucked to it with ambulacral legs, and at the expense of the muscular tension he opens the sashes.
