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). Bears 2 young in summer (Ref. 5578). Gives birth to litters of 1-4 pups; born at 18-21 cm WD (Ref.58048).

Likely confined to the inner continental shelf (Ref. 9840), over sandy and mud bottoms (Ref. 30573). Recorded from coastal waters and river mouths (Ref. 45255). Feeds on bottom crustaceans including shrimp, crabs and small lobsters (Ref. 5578). Ovoviviparous (Ref. 50449). Important food fish, the skin and flesh are dried or used to produce leather for purses and bags (Ref. 9840). Caught in very large quantities in the demersal tangle net, bottom trawl and trammel net fisheries. Utilized for its meat, skin (high value) and cartilage (Ref. 58048). It is parasitised on the dorsal skin surface by the monogeneans Dendromonocotyle citrosa, D. colorni, D. ukuthena (Ref. 124058) and D. lotteri (Ref. 124051).

Whitespotted whipray
(
Inglês
)
fornecido por wikipedia EN
The whitespotted whipray or sharpnose stingray (Maculabatis gerrardi) is a species of stingray in the family Dasyatidae. It is found in coastal regions including estuaries, in the Indo-Pacific, and has also been recorded in the Ganges River. It reaches a maximum length of 2 metres (6½ ft). As presently defined, it is probably a species complex.[2]

The Stingray is named in honor of Edward Gerrard (1810-1910), a taxidermist at the British Museum of Natural History, who with his shark and ray identifications assisted Gray.[3]
