Etymology: Pterois: Greek, pteron = wing, fin (Ref. 45335). More on authors: Jordan & Evermann.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 3 - 122 m (Ref. 3921). Tropical
Eastern Central Pacific: known only from Hawaii.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 22.0 cm TL male/unsexed; (Ref. 3921)
soft rays: 6 - 8. Pectoral rays all unbranched, very long and free from membrane distally; dorsal spines very long, some about as long as body depth. Ctenoid scales with about 50-55 vertical scale rows; coronal spines present; most head spines become multiple with growth. Lachrymal and suborbital bones densely covered with spines for specimen 10 cm SL. Supraocular tentacles banded with black, frequently tentacles absent in large specimens. Small specimens with fewer bars on pectoral and pelvic fins.
Inhabits lagoon and seaward reefs (Ref. 9710). Benthic (Ref. 58302). Generally hidden beneath ledges or caves during the day; a nocturnal feeder on crustaceans (Ref. 3921).
