Groupers are fish of any of a number of genera in the subfamily Epinephelinae of the family Serranidae , in the order Perciformes. Not all serranids are called 'groupers'; the family also includes the sea basses. The common name 'grouper' is usually given to fish in one of two large genera : Epinephelus and Mycteroperca.

Kreature Feature started off as an educational presentation at our monthly general staff meetings here at the Two Oceans Aquarium. Every month PA to Head of Education Katja Rockstroh presents a different animal that we have here at the Aquarium and tells our colleagues more about it. Usually she uncovers some rather interesting facts about the various animals she researches.

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. A few grouper species, however, may carry toxic substances produced by dinoflagellates that bioaccumulate in their flesh increase in concentration at the higher end of a food chain and can cause ciguatera, a rarely fatal form of poisoning , when consumed.

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.
