Short description Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 15-16; Anal spines: 4; Anal soft rays: 9 - 10. Tip of membranes of spinous dorsal fin reddish or translucent, not whitish; posterior margin of upper jaw reaching posterior margin of pupil (Ref. 13608). Spiny and soft parts of dorsal fin nearly separate, but connected by low membrane (Ref. 26938). Dull red or pinkish, sometimes blotched (Ref. 7251).

Biology     Glossary (e.g. epibenthic)

Occurs in shallow coral reefs, as well as deeper offshore waters (Ref. 3724). A nocturnal species, hiding in deep crevices or under coral ledges during the day; at night it usually moves over sand and grass beds, taking mainly crabs and other small crustaceans (Ref. 3634). Capable of producing sounds (Ref. 6537). Spawning documented as far north as North Carolina in May (Ref. 27549). Marketed fresh (Ref. 3724).
