Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 36.0 cm TL male/unsexed; (Ref. 1371)
Dorsal spines (total): 2; Anal spines: 0. Snout slightly long and pointed, with broad triangular naked areas on the dorsal surface; the terminal scute small, poorly defined in larger individuals. Overall color is light brown with a large ocellated black blotch above and behind the pectoral fin bases; a fainter saddle just below the anterior end of the second dorsal fin extending 2 to 3 rows below the lateral line. The mouth cavity whitish; the gill cavity blackish; the fins generally dusky except for the blackish pelvic fins.
Captured at depths from 200 to more than 600 m (Ref. 95664). Feeds primarily on polychaetes with crustaceans of minor importance (Ref. 1371).

Estimates based on models
Preferred temperature (Ref.
123201): 10.3 - 16.2, mean 14.1 °C (based on 10 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00251 (0.00128 - 0.00492), b=3.19 (3.03 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.40 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): Low to moderate vulnerability (26 of 100).
