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.
Common sea stars are sexually mature after 1 year, and are thought to live for 5-10 years. During asexual reproduction, the sea star divides its disk so that it breaks into two halves. Each half regenerates into a new sea star. Sea stars can also lose an arm (e.g., when attacked by a predator) and regrow it.iet and Feeding. Common sea stars eat mollusks, including bivalves (a favorite prey item is the blue mussel) and gastropods. They also eat crustaceans and worms. They act both as active predators and scavengers.
