簡単な記述 検索表 | 形態学 | 形態計測学

A thick, dark stingray with a broadly rounded snout and an angular pectoral disc; tail less than twice body length with a long lower caudal finfold ending far in front of tail tip, but with no upper finfold; disc without thorns; usually 1 extremely long sting on tail; eyes do not protrude (Ref. 5578). Uniformly violet, purple, or dark blue-green dorsally and ventrally (Ref. 3263). No prominent markings (Ref. 3263).

生物学     用語集 (例 epibenthic)

Found in open, tropical and warm temperate waters usually in the first 100 m. Possibly the only totally pelagic member of the family (Ref. 6871). Feeds on coelenterates (including medusae), squid, decapod crustaceans, and fish. Ovoviviparous (Ref. 50449). Venomous spine on tail. Common catch of the pelagic tuna (and shark) longline and gillnet fisheries (drift, Ref. 75025) operating throughout the region (Ref. 58048); also by purse-seine and bottom trawls (Ref. 75025). Utilized for its meat and sometimes cartilage (Ref.58048). Total length 110 TL (80 cm WD) (Ref. 9254).

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 幼生

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). With 2 (Ref.58048) to 9 young born at 15-25 cm WD (Ref. 26346); after a gestation period of 4 months (Ref.58048).
