Bermuda sea chub
(Kyphosus sectatrix)

Kyphosus sectatrix, the Bermuda chub, Pacific drummer, beaked chub, grey drummer, Pacific chub or white chub, is a species of marine ray-finned fish, a sea chub from the family Kyphosidae. This species is found in tropical and subtropical coastal waters worldwide.

Kyphosus sectatrix has an elliptical body which is almost circular when looked at from the side, with a head than slopes from over the eye to the snout, making the fish appear to be beaked or snouted. It lacks an obvious bulge on its forehead and it has a small, horizontal mouth which opens at the front. There is a regular row of incisorform J shaped teeth with rounded tips which are set close together in the jaws which have their bases set horizontally creating something like a bony plate with radial striations within the mouth.

Ctenoid scales cover most of the body apart from the snout. The dorsal fin is continuous, and has its origin quite far to the rear of the head and longer than the anal fin. The dorsal fin contains 11 spines and 11–12 soft rays while the anal fin has 3 spines and 11 soft rays. The caudal fin is emarginate but not deeply so.

The lateral line has 63–81 scales of which 50–62 have pores.

This species may attain a maximum total length of 76 centimetres (30 in); a total length of around 50 centimetres (20 in) is more common. The maximum weight attained is 6 kilograms (13 lb).

The colour of this species can be variable, normally it is greenish to bronze dorsally fading to pale greyish on the flanks and to silvery ventrally. There are faint gold horizontal lines on the body and there is frequently a white or silvery streak on the cheek below the eye, and a narrow pale stripe below the dorsal fin base. Sometimes individuals which are bright yellow in colour occur and these often have blotches or patches of black along with areas of paler yellow or whitish colour. The juveniles are grey and have white or pale spots on their bodies and fins.
