The Slender Grouper (Anyperodon Leucogrammicus) is the only species in the genus. It is found in tropical parts of the Indo-Pacific Ocean.

Description[]

The slender grouper is a medium fish growing to a length of about 65 centimetres (26 in). The head occupies 40% of the total length and the mouth is large, with the lower jaw longer than the upper jaw. There are no palatine teeth, a fact which distinguishes this species from other groupers. The basic colour is pale reddish-brown liberally dotted with orange spots which are closer together on the head. There are five pale silvery blue longitudinal lines running down either side, the lower 3 reaching the tail but the upper two breaking into irregular streaks. The dorsal fin has 11 spines and 14 to 16 soft rays. The anal fin has 3 spines and 8 to 9 soft rays. Juvenile fish have vivid blue and red longitudinal stripes.

Distribution and Habitat[]

The slender grouper has a wide distribution in the tropical Indian and Pacific Oceans. The range extends from the east coast of Africa and the Red Sea at 32°E to southern Japan and Australia at 171°W. It is found on coral reefs and seaward reef slopes and in lagoons at depths down to 50 metres (160 ft) or occasionally 80 metres (260 ft).

Ecology[]

The slender grouper is carnivorous, feeding mainly on other fish such as goatfish but possibly also on invertebrates. Juvenile slender groupers are aggressive mimics of the red-lined wrasse, and the silty wrasse. They resemble them in appearance and in behaviour which lulls a potential prey fish into a false sense of security and enables the grouper to approach it without detection.

Concervation Status[]

The slender grouper is considered of "least concern" by the IUCN Red List of Threatened Species. This is because it has a very wide range and populations do not seem to be in decline.[1] It is not fished commercially but is occasionally seen in the fish markets in Hong Kong.
