Occur in a variety of habitats, over mud, sand and gravel bottoms; over coral reefs, off rocky shores and in mangrove sloughs; inshore around pilings and buoys, and offshore around drifting and stationary objects; occasionally in estuaries. Form small groups and may pursue small pelagic inshore. Feed on crabs, fishes, and squids. Spawn during the warm months in the western Atlantic; eggs and larvae planktonic. Caught in small quantities due to its solitary behavior. Good food fish; marketed fresh , smoked, and frozen. Also caught for sport.
