Etymology: Hypsypops: Greek, hypsy, hypops = high + Greek, ops = appearance (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 0 - 30 m (Ref. 9334). Subtropical; 37°N - 27°N, 122°W - 114°W
Eastern Central Pacific: Monterey Bay in California, USA to southern Baja California and Guadalupe Island (off northern central Baja California) in Mexico.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm SL male/unsexed; (Ref. 7247); max. reported age: 20 years (Ref. 52465)
Adults occur over rocky bottom in clear water, often near crevices and small caves, occasionally in kelp. Adults defend a home territory. Feed mainly on attached invertebrates. Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Have been reared in captivity (Ref. 35420).

Oviparous, distinct pairing during breeding (Ref. 205). Male clears a sheltered nest site; female deposits eggs, which male guards (Ref. 2850).
