Trophic Strategy

Read full entry

L. alternata usually preys on other echinoderms like brittle stars, but on occasion they consume dead bait thrown overboard by fishermen. Since it is a common inhabitant of scallop beds off the Carolina coast, it usually preys on small individuals of the sea star species Astropecten articulatus. Because their tube feet lack the suckers needed to open bivalves, they swallow their prey whole, then regurgitate the undigestable portions.
