Grey Seabream

Gymnocranius griseus has its dorsal fin supported by 10 spines and 10 soft rays while the anal fin has 3 spines and 9 or 10 soft rays. It has an oblong shaped body with a depth which fits into its standard length between 1.9 and 2.3 times. The snout is pointed and the front of the jaw has three pairs of canine like teeth, with the other teeth being bristle-like, although they become more conical along the sides. The caudal fin is moderately forked and has pointed tips to its lobes. This is a silvery coloured bream with between5 and 8 slender black vertical bars on the flanks with the first running through the eye and across the cheek. This species has a maximum published total length of 35 cm (14 in), although 25 cm (9.8 in) is more typical.

Gymnocranius griseus is found in the Western Pacific Ocean from southern Japan south into the Malay Archipelago and from western Australia east to the Marianas Islands. It has been claimed from the Indian Ocean but these records are likely to be misidentifications of G. grandoculis. This species is found in inshore waters at depths greater than 20 m (66 ft) in sheltered bays and on sand and mud slopes. Juveniles are occasionally found on algal reefs in brackish estuaries.

Gymnocranius griseus has the specific name griseus which means "grey", Temminck and Schlegel described the fish as having a "very pale bluish grey" colour in life.
