Description synthétique Morphologie | Morphométrie

Disc rhomboid, anterior margin straight, posterior margin convex. Snout triangular and slightly produced. dorsal keel present on tail. Adults with small spines on disc and posterior part of tail. Brown dorsally and some with orangish pectoral fin margins, in front of eyes, behind spiracles, on the sides of the tail just anterior to the sting. Ventrum orangish red.

Biologie     Glossaire (ex. epibenthic)

Found in coral reefs and estuarine areas, on sand and mud bottoms (Ref. 12951, 11230). Feeds on small fishes and crustaceans (Ref. 9840). Ovoviviparous with litters of only 1 pup (Ref. 114953) while earlier estimates indicated production of up to 10 in a litter (Ref. 12951). Caught occasionally by bottom trawl fisheries operating inshore. Utilized for its meat but of limited value due to its small size (Ref.58048). Served in 'miso' soup, hard boiled with seasonings, or for 'kamaboko' material (Ref. 637).

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).
