Etymology: Kyphosus: Greek, kyphos = bent (Ref. 45335).
Environment / Climate / Range
Marine; pelagic-oceanic; depth range 1 - 20 m (Ref. 89972). Tropical; 37°N - 18°S, 138°E - 77°W
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 59.0 cm TL male/unsexed; (Ref. 38398); common length : 25.0 cm TL male/unsexed; (Ref. 55763); max. published weight: 2.0 kg (Ref. 38398)
Body oval elongate, and somewhat compressed (depth contained more than 2.5 times in standard length); head and mouth small; teeth highly characteristic, forming a single anterior row in each jaw, incisiform and somewhat lanceolate in shape, resembling the head of a golf club, their roots compressed and horizontally set, forming a striated plate inside the mouth, although this feature might be little evident; vomer toothed; caudal fin deeply forked; body with wide shiny blue and yellow stripes; fins yellowish (Ref. 55763).
Eastern Pacific: from Galapagos to Hawaii and across the Pacific to SE Japan, Guam and Palau, and Marquesas; possibly Micronesia.
Occurs both as solitary individuals and in schools together with K. elegans and K. vaigiensis and are found close to the surface (< 25 m) on rocky shores, the open ocean and reefs on isolated islands (Ref. 95491). Also swim rapidly in small, somewhat polarized groups or schools in open water over deep reefs, along walls and drop-offs (Ref. 5227) or usually seen near floating logs far out to sea (Ref. 11482). This species differs from its congeners in having an omnivorous diet that includes zooplankton (Ref. 95491). Not common.
