Short description 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 of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.36 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100) .
