Description synthétique Morphologie | Morphométrie

Moderate size, with a short blunt snout. Disk has rounded corners, few tubercles and spines along midline (Ref. 26938). Well developed fold on the upper surface and lower surface of tail. Yellowish or light brown above. Lower surface whitish or pure white (Ref. 6902).

Biologie     Glossaire (ex. epibenthic)

Inhabits coastal waters (Ref. 7251). Generally found near shore, to depths of 10 m. Both adults and juveniles frequent estuaries and surf zones (Ref. 27549). Bottom feeder with fish, clams, worms and shrimps. It causes a number of injuries to bathers and waders (Ref. 26938). Ovoviviparous (Ref. 50449). Litters of 2-4 pups; gestation 10-11 months, including a period of embryonic diapause (Ref. 114953).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

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).
