Found over sandy bottoms of coastal areas and also in areas with some seagrass or algae. Ranges to a depth of over 18 m (Ref. 9710). Usually in large spread-out groups on upper slopes of sand and mud banks with males defending its section that has numerous females (Ref. 48636). When threatened, it dives head-first into sand; may take some time to emerge again. Feeds mainly on hard-shelled prey, including mollusks and crustaceans (Ref. 5374).
