The Malabar grouper or greasy grouper, Epinephelus malabaricus, is a species of marine fish in the family Serranidae.[3]

Distribution and habitat

The Malabar grouper is widespread throughout the tropical waters of the Indo-West Pacific area from the eastern coast of Africa to the Tonga Islands, Red Sea included.[3][1]> It has also been recorded in the Levantine Sea and the eastern Mediterranean, as a Lessespian migrant through the Suez Canal, although it is still rather rare in the Mediterranean.[4] This grouper lives in various habitats, such as lagoons, mangroves, coral and rocky reefs, sandy and muddy bottom areas,[5] between 2 and 150 m deep.[6] The juveniles prefers lagoon or brackish areas.[5]

Description

The Malabar grouper can reach a length up to 234 cm (92 in), but average size is usually around 100 cm (39 in).[7] It has a light grey to light brownish background color, with a number of dark brown spots randomly scattered, which increase in number with age. The body has also a various number of brown diagonal stripes. Younger fish have a number of wide, broken vertical bands of darker shade across their bodies, but in maturity they seem to become a uniform darker colour. Young fish have numerous brown spots. The tail fin is rounded.[8]

Biology

Epinephelus malabaricus is a protogynous hermaphrodite, as these fishes at some point in their lifespan change sex from female to male.[6] Malabar grouper are voracious predators, they feed on fish, crustaceans, and occasionally, cephalopods.[9]

Parasites

As most fish, the Malabar grouper harbours a variety of parasites, including the diplectanid monogeneans Pseudorhabdosynochus manifestus, P. maaensis, P. malabaricus, P. manipulus, P. marcellus, and P. maternus.[10]

Uses

Malabar groupers are harvested for food, sport, and commercially; some are grown in aquaculture.
