Short description Morphology | Morphometrics

Dorsal spines (total): 2; Anal spines: 0. Snout narrow, bluntly rounded, almost entirely bare, with a small inconspicuous scute at its tip. Suborbital ridge rounded and shallow in cross section, without scute-like scales. Cephalic pores of the lateralis system indistinct, but sensory papillae densely dispersed over the head. Pyloric caeca 25 to 37. Body scales small, easily shed, mostly without spinules, but some with slanting conical spinules. Overall color is Grayish brown with violet tinged; abdominal region, gill membranes and gill cover blackish; oral and branchial cavities and fins dusky to blackish.

Biology     Glossary (e.g. epibenthic)

Caught as a by-catch of trawlers fishing for Dover sole but of no commercial value (Ref. 9315). Problems with taxonomy. Shallowest depth record from Ref. 37930.

Estimates based on models

Preferred temperature (Ref. 123201): 3.8 - 4.9, mean 4.1 °C (based on 23 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00166 (0.00100 - 0.00276), b=3.12 (2.97 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.1 se; based on size and trophs of closest relatives
Generation time: 1.6 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (22 of 100).
Price category (Ref. 80766):   Medium.
