The red grouper (Epinephelus morio) is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the western Atlantic Ocean.

R
starts withThe red grouper has a body with a standard length which is 2.6 to 3 times as long as it is deep. The preopercle is subangular with the serrations at its angle being slightly enlarged and the upper edge of the gill cover is straight. The gill cover has three flat spines with the central spine being the longest. The dorsal fin contains 11 spines and 16-17 soft rays while the anal fin has 3 spines and 8 soft rays. The pectoral fins are longer than the pelvic fins and the caudal fin is truncate. The They are dark reddish brown on the upper part of the head and body, shading to paler pink on the underparts, they are marked with lighter spots and blotches across their body and there are darker margins to the fins. This species has a maximum published total length of 125 centimetres (49 in), although they a more commonly found at lengths around 50 centimetres (20 in), and a maximum published weight of 23 kilograms (51 lb).
The red grouper's typical range is coastal areas in the western Atlantic, stretching from southern Brazil to North Carolina in the US and including the Gulf of Mexico and Bermuda.
The red grouper is a demersal, largely sedentary species which has an extended (~40 day) pelagic larval stage before it settles in shallow coastal hardbottom habitat as juveniles. They remain in inshore waters for 4–5 years before migrating to offshore hardbottom habitat—particularly on the edge of the continental self—as adults. Spawning occurs offshore between January and June, peaking in May. While primarily eating benthic invertebrates, the red grouper is an opportunistic feeder in the reef community. The diet commonly includes xanthid and portunid crabs, juvenile spiny lobster, and snapping shrimp, with the occasional fish. The red grouper is of moderate size, about 125 cm and weighs 23 kg or more. Body coloration is typically reddish-brown in color often, with many white spots. When aggravated (they are highly territorial) or involved in spawning activities, these fish can very rapidly change coloration patterns, with the head or other parts of the body turning completely white, and the white spots appearing more intense.
