Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Found on the outer continental shelf and upper slopes. Bottom-dweller which feeds on invertebrates, mainly on crustaceans such as shrimps and prawns (Ref. 114953) and bony fish (Ref. 9908). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Males reaches maturity at ca. 30 cm TL, females at ca. 32 cm TL (Ref. 114953).

Estimates based on models

Preferred temperature (Ref. 123201): 19.7 - 20.5, mean 19.8 °C (based on 6 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00324 (0.00152 - 0.00688), b=3.22 (3.05 - 3.39), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.61 se; based on food items.
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (26 of 100).
