The black grouper is a fairly large and hard-ﬁghting member of the Serranidae family. It is an excellent food fish, although the flesh is occasionally toxic and can cause ciguatera.
IdentificationDepending on location, the black grouper may be olive, gray, or reddish-brown to black. It has black, almost rectangular blotches and brassy spots. It can pale or darken until its markings are hardly noticeable.
It has a thin, pale border on its pectoral ﬁns, a wide black edge and a thin white margin on its tail, and sometimes a narrow orangish edge to the pectoral ﬁn; the tips of the tail and the soft dorsal and anal fins are bluish or black. The black grouper has a squared-off tail and a gently rounded gill cover.
