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.
The Purple Sea star is a medium size animal found on rocky shores where it feeds primarily on barnacles. Its arms are relatively short (R/r = 2.7 to 4.1)* Although its common name implies that it is most often purple, it is as likely to be some shade of orange or brown but never pink.
