Like other tunicates, this sea squirt draws in large quantities of water through its buccal siphon, filters out the edible particles and expels the water through the atrial siphon. Among the planktonic particles ingested are a variety of invertebrate larvae, however researchers have found that the activities of the sea squirt are not sufficient to deplete the local larval populations appreciably. The diet includes the eggs and larvae of crustaceans, echinoderms, mollusks and other tunicates.
