Answer by Marcin Wojtkowski. Confidence votes 167. Most sea star (starfish) species are generalist predators, some eating bivalves like mussels, clams, and oysters; or any animal slow enough to be unable to evade the attack (e.g. dying fish). Some species are detritivores, eating decomposed animal and plant material, or organic films attached to substrate.
Sea stars are invertebrates related to sea urchins, sea cucumbers and sand dollars, which are all echinoderms. Echinoderm means spiny skinâa reference to their hard, calcified skin, which helps to protect them from predators. Sea stars have rows of tiny tube feet extending from the grooved surface on their underside.
