Kuhlia mugil

Kuhlia mugil has a compressed body which is shaped like an elongated oval with a large eye and an oblique mouth which has a projecting lower jaw.[3] It is covered with moderately large ctenoid scales. It is normally silver in colour, although the upper flanks sometimes show a bluish, brownish or yellowish tinge. The caudal fin has a pattern of five dark bars alternating with paler areas.[4] There is a dusky band along the margin of the soft rayed portion of the dorsal fin except for a white tip on highest anterior part.[2] The tip of the snout and the tip of the chain are blackish.[5] The dorsal fin is deeply notched.[3] There are 10 spines and 10-11 soft rays in the dorsal fin with 3 spines and 10-12 soft rays in the anal fin. It can attain a standard length of 40 centimetres (16 in).[2]

Kuhlia mugil has a widespread distribution which encompasses the Indian Ocean and the Pacific Ocean. It is found from the Red Sea and the east African coast east through the Indo-Pacific to the eastern Pacific islands of Clipperton, Cocos and Revillagigedo. The range extends north to southern Japan, and south to Australia.[1] In Australia the range extends from the Torres Strait to Seal Rocks, New South Wales as well as Lord Howe Island and Norfolk Island in the Tasman Sea and the Cocos (Keeling) Islands and Christmas Island in the Indian Ocean.[5] In the eastern Pacific they are found at the tip of Baja California and along the coast from Costa Rica to Colombia.[3] The species is absent from the Marquesas, Hawaii and Easter Island, Pitcairn Island, and Johnston Island.[2]

This species occurs on reefs at depths of 3 to 18 m (9.8 to 59.1 ft), where they form tightly packed schools. Young fish can also be found in tide pools. This species has also been reported occasionally from estuaries but never from fresh waters.[2] It is a nocturnal forager, preying mainly on zooplankton and small fishes.[5]

Kuhlia mugil is caught for food, bait, and the aquarium trade. Fishermen use seines, gill nets and hook and line to catch them.[1] It is sold fresh or preserved by drying and salting.[2]
