Most species have five feathery-fringed arms. Feather stars usually attach themselves to a surface or a floating object and feed on drifting microorganisms, trapping them in their sticky arm grooves. They live mainly on rocky bottoms in shallow water. Most abundant from the Indian Ocean to Japan, they are also found in the Atlantic
