Brown-marbled grouper
The brown-marbled grouper or tiger grouper (Epinephelus fuscoguttatus) is a benthic marine fish which belongs to the family Serranidae or also known as the groupers.
Epinephelus fuscoguttatus is a medium-sized fish which grows up to 120 cm, but the average size mostly observed is 50 cm. Its body has a stocky and robust aspect, is compressed laterally, and has a sharp profile for the head. The mouth is big and has a superior position with many small teeth and canines in front. The background coloration is pale yellowish-brown with many dark brown or grey blotches that are irregular in size and shape. The body is also covered with many small, dark brown spots. All the fins are large and round.
The brown-marbled grouper can be easily confused with its close relative Epinephelus polyphekadion. The differences are more obvious in adult specimens. The distinctive characteristics of the brown-marbled grouper are: a small black saddle on the top of the caudal peduncle, when observed on the side a notch above the eyes, and the front head is clearly visible, its body is quite thick from the front of the dorsal fin to the bottom of the fish below the pectoral fins.
It is widely distributed throughout the tropical and subtropical waters of the Indo-Pacific, from the eastern coasts of Africa to the oceanic islands of the centre of the Pacific Ocean, Red Sea included. However, it is absent from the Persian Gulf, Hawaii, and French Polynesia.
Like many of the groupers, the brown-marbled grouper lives in rich clear waters close to coral or rocky reefs, lagoons, and external slopes from the surface until 60 metres (200 ft) depth.
The brown-marbled grouper is carnivorous and its diet consists mainly in fishes, crustaceans and cephalopods. It is an ambush predator.
This grouper is solitary and sedentary; it defends a well-defined territory, benthic, and is nocturnal, with activity maximal at sunrise and/or at sunset.
It has a quite long life span for a fish and is expected to live until at least 40 years old.
