Common over shallow sand flats, in channels, and around coral reefs; Young may be found among prop roots of red mangroves (Ref. 26938). Found on continental and insular shelves. A solitary (Ref. 26340) and sluggish fish, often encountered lying on the bottom (Ref. 9987). Nocturnal, feeding on bottom invertebrates such as spiny lobsters, shrimps, crabs, sea urchins, squids, octopi, snails and bivalves, and fishes like catfishes, mullets, puffers and stingrays. Algae is occasionally found in its stomach. This species feeds by sucking in food at high speed through its small mouth and large, bellows-like pharynx. It feeds on big, heavy-shelled conchs by flipping them over and extracting the snail from its shell, presumably with its teeth and by suction. Carnivore (Ref. 57616).
