Etymology: Stegastes: Greek, stegastos, -e, -on = covered (Ref. 45335). More on author: Gill.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 1 - 10 m (Ref. 57763). Subtropical; 32°N - 23°N
Eastern Central Pacific: Mexico, including the Gulf of California.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 13.5 cm TL male/unsexed; (Ref. 59088); common length : 8.0 cm TL male/unsexed; (Ref. 55763); max. reported age: 11 years (Ref. 52465)
Adults inhabit rocky inshore reefs (Ref. 9334). Omnivorous (Ref. 9334). 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).
