Biologie     Glossaire (ex. epibenthic)

Found in mangrove areas, also over sand or sand and rubble in lagoons near reefs to depth of 85 m on the continental shelf (Ref. 9840). Feeds on small fishes, bottom dwelling crustaceans, and large infauna (Ref. 9840). Ovoviviparous (Ref. 50449), with histotrophy. Caught regularly, but in low numbers, by demersal tangle net and bottom trawl fisheries. Utilized for its meat, skin (high value) and cartilage (Ref.58048).

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). Fully developed young, size at birth 28 cm (Ref. 37816, Ref.58048).
