Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 11; членистые (мягкие) лучи спинного плавника (общее число) : 18 - 20; колючие лучи анального плавника: 3; членистые (мягкие) лучи анального плавника: 9. Distinguished by the following characteristics: body depth, 2.1-2.5 in SL; dorsal profile of head is steep; eye diameter less than snout length, 5.2-8.0 in HL; short pectoral fins, length 18-26% of SL; rounded caudal fin; smooth scales, mostly covered by skin; lateral line scales 62-67 (Ref. 089707).
A diurnal predator that feeds on small benthic fishes and occasionally on crustaceans. Often it uses browsing herbivorous fishes as a moving blind in order to feed on the cryptic fauna disturbed by these browsers; it will also follow foraging moray eels to catch the fishes frightened from their hiding places. Small juveniles have been seen hiding among the long spines of the dark-colored sea urchin, Centrostephanus coronatus.
