Biology     Glossary (e.g. epibenthic)

Generally found offshore, but may also encountered in coastal areas (Ref. 9279). Oviparous (Ref. 205). Eggs may be found attached to objects in the water by tendrils on the egg's surface (Ref. 205). Usually caught with the help of artificial lights (Ref. 9279). Marketed fresh and salted (Ref. 9279). The flesh is of good quality (Ref. 9279).

Bayesian length-weight a=0.00072 (0.00039 - 0.00136), b=3.11 (2.95 - 3.27), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level
(Ref. 69278) 		4.5   ±0.7 se; based on size and trophs of closest relatives
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		High vulnerability (56 of 100). 🛈
