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

Found on the continental shelf and littoral areas (Ref. 247).A sluggish and inactive species that buries itself in sand or mud (Ref. 247). Also found around rocks, heads of submarine canyons, and sometimes near kelp forests (Ref. 247). Feeds on bottom and epibenthic fishes, including croakers, California halibut, and squid (Ref. 247). Ovoviviparous (Ref. 50449). Can whip up its head and snap very quickly when touched, provoked, harassed, or speared, and can inflict painful lacerations (Ref. 247).

Estimates based on models

Preferred temperature (Ref. 115969): 12.5 - 25.9, mean 21 °C (based on 60 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00273 - 0.01920), b=3.04 (2.81 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.1   ±0.4 se; based on diet studies.
Generation time: 7.2 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Widerstandsfähigkeit (Ref. 120179):  sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (K=0.15-0.16; tm=8-13; tmax=35; Fec=6).
Verwundbarkeit (Ref. 59153):  High vulnerability (65 of 100) .
