(Perch-likes) > Embiotocidae
Etymology: Hyperprosopon: Greek, hyper = over + Greek, prosopon = face, snout of animal (Ref. 45335); ellipticum: From the Latin 'ellipticum' - referring to the outline of the body (Ref. 6885).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 0 - 110 m (Ref. 2850). Subtropical; 55°N - 30°N, 134°W - 115°W
Eastern Pacific: southern British Columbia, Canada to Rio San Vincente, northern Baja California, Mexico.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 27.0 cm TL male/unsexed; (Ref. 2850); max. reported age: 7 years (Ref. 56049)
(total): 8 - 10;
soft rays: 29 - 34. Dark green dorsally, sides and belly silvery; a series of narrow vertical bars of pale golden pink on body wall; pectoral fins colorless (Ref. 6885). British Columbia specimens dark on end of caudal fin and free edge of spinous dorsal (Ref. 6885).
Found inshore, in surf and sandy areas, also occur around rocks and piers (Ref. 2850). Intertidal and to 110 m (Ref. 96339). Viviparous, female carries the developing young (Ref. 205). Frequently caught, but not of much importance as a sport fish due to its small size (Ref. 2850).
