Espinas dorsales (total) : 15; Radios blandos dorsales (total) : 10; Espinas anales: 2; Radios blandos anales: 10 - 11.
Adults occur in inshore and offshore rocky reefs in 5 to 30 meters in small to large aggregations (Ref. 7247). 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).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00571 - 0.02773), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nivel trófico (Ref.
69278): 3.0 ±0.1 se; based on size and trophs of closest relatives
Resiliencia (Ref.
