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: Baja California to Peru, but have been taken in the artificially warmed waters off the Encina Power Plant in San Diego, California, USA, far outside normal range. Northwest Pacific: Hachijôjima, Japan (Ref. 559). Central Pacific: Hawaii and the Society Islands (Ref. 559).
Swim rapidly in small, somewhat polarized groups or schools in open water over deep reefs, along walls and drop-offs (Ref. 5227). Also usually seen near floating logs far out to sea (Ref. 11482). Not common.
