Biology     Glossary (e.g. epibenthic)

Inhabits muddy bottoms with preference for depths 100 to 140 m. Feeds mainly on fish (Ref. 1967). Oviparous (Ref. 205). Both male and female guard the eggs (Ref. 52177). An important food fish (Ref. 4537)

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.5   ±0.80 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (45 of 100).
Price category (Ref. 80766):   Unknown.
