Biologia     Glossario (es. epibenthic)

Found in shallow bays, sheltered sandy beaches in summertime, moves to deeper waters during winter. Feeds on bony fishes and crustaceans such as crabs, shrimps and mantis shrimps (Ref. 36731); including sea lice and marine worms (Ref. 114953). Ovoviviparous (Ref. 50449). Litters of 1-5 pups (Ref. 114953). Often caught by shore anglers (Ref. 36731). It is parasitised by the monogenean Dendromonocotyle citrosa on the dorsal skin surface (Ref. 124058).

Life cycle and mating behavior Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve

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. 123201): 17.2 - 26.7, mean 24.8 °C (based on 64 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00265 - 0.01571), b=3.06 (2.86 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.65 se; based on food items.
Generation time: 15.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilienza (Ref. 120179):  Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Assuming fecundity<100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (78 of 100).
