Distribution:  Eastern Pacific: Gulf of California to Peru, including the Revillagigedo, Galapagos, Clipperton, Cocos, and Malpelo islands.
Diagnosis:  Dorsal spines (total): 9-9; Dorsal soft rays (total): 18-21; Anal spines: 3-3; Anal soft rays: 9-11.

Biology:  Found typically in small aggregations well above the reef, but will retreat to the reef at the approach of danger. Feeds mainly on small planktonic animals picked individually from the water, made possible by their shortened snout which facilitates close-range binocular vision. Excellent source of bait (Ref. 9342).
