Note
Lytechinus variegatus is usually thought of as a sedentary or slow-moving herbivore incapable of feeding on other than benthic flora and fauna. Thus, it was surprising to observe one of these urchins capture, kill and ingest a free-swimming juvenile mullet Mugil curema (Cuvier & Valenciennes). In this paper we briefly describe our observations of this behavior and suggest reasons for its occurrence.
