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).
Ciclo vital y comportamiento de apareamiento
Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva
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).
