Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 108-114; Anal spines: 0; Anal soft rays: 92 - 97. No lateral line on ocular side. Light brownish on ocular side, with 9 to 10 indistinct dark bands; posterior parts of dorsal and fin membranes blackish; no black blotch on dorsal and anal fins and opercle (Ref. 27363).

Biology     Glossary (e.g. epibenthic)

Occurs in coastal areas (Ref. 36453). Mainly feeds on polychaetes; also on other benthic preys such as gammaridean amphipods, cumaceans, and mysids. A "smell and touch" kind of predator, little is known regarding its ecology (Ref. 26268).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00468 (0.00266 - 0.00822), b=3.16 (3.00 - 3.32), based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.43 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 vulnerability (42 of 100) .
