Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; bathydemersal; non-migratory; depth range 720 - 2400 m (Ref. 9315). Deep-water; 24°N - 6°S, 112°W - 78°W (Ref. 1371)
Eastern Pacific: off the Pacific coast from Mexico to Peru, including the Galapagos Islands.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 50.0 cm TL male/unsexed; (Ref. 1371)
Dorsal spines (total): 2; Anal spines: 0. Snout prominent, pointed; chin with very short barbel. Scales highly deciduous; ventral and leading surfaces of the snout naked; suborbital region dorsally mostly naked; suborbital ridge scales small if present; head ridges without enlarged scute-like scales. Overall color is gray brown to dark brown; oral cavity pale to grayish.
A deep-slope species of the tropical eastern Pacific (Ref. 9315). Polychaetes and benthic crustaceans are encountered in its stomach contents (Ref. 9315). Fairly common but of no commercial value (Ref. 9315).

Estimates based on models
Preferred temperature (Ref.
123201): 3.3 - 4.5, mean 3.7 °C (based on 34 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00214 (0.00109 - 0.00421), b=3.20 (3.03 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.39 se; based on food items.
Resilience (Ref.
120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate vulnerability (40 of 100).
