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

Inhabits sandy areas, often around rocks and kelp beds (Ref. 2850). Benthic (Ref. 58302). Feeds on crabs and mollusks (Ref. 4925); and worms (Ref. 114953). Ovoviviparous (Ref. 50449); litters of 1-4 pups and gestation period of approx. 3 months (Ref. 114953).

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 115969): 12.1 - 21.3, mean 14.9 (based on 102 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00279 - 0.01637), b=3.07 (2.87 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.50 se; Based on food items.
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Assuming fecundity<100).
Verwundbarkeit (Ref. 59153):  High to very high vulnerability (72 of 100) .
