Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 25 m (Ref. 57763). Tropical; 27°N -
Eastern Pacific: Gulf of California to Peru, including the Galapagos Islands.

Maturity: Lm ?  range ? - ? cm
Max length : 120 cm TL male/unsexed; (Ref. 57763); common length : 60.0 cm TL male/unsexed; (Ref. 57763)
Lives in rocky, boulder strewn areas and walls. Lurks in holes, crevices and dark recesses. Constantly opens and closes its mouth, an action required for respiration, not a threat (Ref. 5227).

Estimates based on models
Preferred temperature (Ref. 123201
): 23.1 - 29.1, mean 27.3 °C (based on 229 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00050 (0.00025 - 0.00101), b=3.26 (3.10 - 3.42), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.0 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): High to very high vulnerability (72 of 100).
