Grouper , any of numerous species of large-mouthed heavy-bodied fishes of the family Serranidae order Perciformes , many belonging to the genera Epinephelus and Mycteroperca. Groupers are widely distributed in warm seas and are often dully coloured in greens or browns, but a number are brighter, more boldly patterned fishes. Some, such as the Nassau grouper Epinephelus striatus , are noted for their ability to change from one to any of a number of other colour patterns. Also, in many species, such as the black and yellowfin groupers Mycteroperca bonaci and M. Groupers are protogynous hermaphrodites ; that is, they first function as females and later transform into males. They are prime food fishes and also provide sport for anglers and spearfishers.

Dusky grouper facts
The giant grouper Epinephelus lanceolatus , also known as the Queensland groper , Queensland grouper , brindle grouper or mottled-brown sea bass , 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 has a wide Indo-Pacific distribution and is one of the largest extant species of bony fish. The giant grouper has a robust body which has a standard length equivalent to 2. The dorsal profile of the head and the intraorbital area are convex, The propercle has a rounded corner and a finely serrated margin. The gill cover has a convex upper margin. There are 54 to 62 scales in its lateral line. The small juveniles are yellow with wide, dark irregular bars and irregular dark spots on their fins.
Management of the goliath grouper, the largest member of the seabass family, has become an intensely debated issue in recent years. The University of Florida has been looking at the most recent science-based information on the biology and ecology of goliath grouper relevant to management issues. Historically, the goliath grouper was relatively common and highly conspicuous in portions of its range. It is a relatively shallow-water species with a tropical to subtropical distribution. In the Eastern Atlantic they occurred from Senegal south to the Congo; however, this population is believed to have been eliminated because no individuals have been observed there for many years. A similar-looking species also occurs in the Pacific Ocean, but recent genetic studies indicate it is a different species.
