Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 50 - 54; Dorsal soft rays (total): 0; Anal soft rays: 35 - 40. Snout blunt; mouth frog-like. With a large fringed tentacle above each eye, a smaller one in front and others on top of head and on the anterior dorsal fin spines. First anal fin ray a short flexible spine. Lateral line represented by a dorsal and a mediolateral branch of neuromasts (the former begins as a short canal, with 4-5 pores.

Biology     Glossary (e.g. epibenthic)

Usually over rocks and among seaweeds, never in intertidal zone, at 20 m, but descends from 100-280 m (Ref. 4782). Benthic (Ref. 58426). Feeds on bottom invertebrates (small mollusks, polychaetes, hydroids, sponges), also algae (Ref. 4782). Spawns in October - December (Ref. 35388).

Estimates based on models

Preferred temperature (Ref. 123201): 6.7 - 12, mean 10.1 °C (based on 278 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00145 - 0.00954), b=3.17 (2.94 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.2   ±0.36 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 vulnerability (21 of 100).
Nutrients (Ref. 124155):  Calcium = 35.6 [18.1, 64.6] mg/100g; Iron = 0.259 [0.148, 0.482] mg/100g; Protein = 17 [16, 18] %; Omega3 = 0.43 [0.21, 0.85] g/100g; Selenium = 17.5 [7.4, 39.2] μg/100g; VitaminA = 34.8 [8.0, 146.6] μg/100g; Zinc = 0.816 [0.551, 1.189] mg/100g (wet weight);
