KYPHOSIDAE (SEA CHUBS OR RUDDERFISHES)

Kyphosus cinerascens (Forsskål)
(High-finned Sea Chub; Guili)
SL: to 37 cm (photo: 14 cm SL, Uruno Pt., 5 m)

This chub is generally found over hard, algae-covered bottoms of seaward reefs from surf-swept reef flats to depths of 24 m or more, as well as on relatively exposed lagoon reefs.  Large specimens are occasionally ciguatoxic.  Juveniles often occur under floating objects well offshore.  Another common species, K. lembus, may be distinguished by its uniformly low soft dorsal and anal fins in which the soft rays do not exceed the spines in length.  The relatively scarce K. bigibbus has a much more elongate body than the other two species as well as low fins.  Guili are considered excellent eating.  They are harvested.by throw net, gilf net, and spear.

INDO-PACIFIC: Red Sea to Mangareva and Hawaii, n. to s. Japan, s. to Queensland, Australia.
