Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; pelagic-oceanic; depth range 1 - 381 m (Ref. 58302), usually 1 - 100 m (Ref. 55209). Subtropical; 52°N - 50°S, 180°W - 180°E (Ref. 55209)

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Probably cosmopolitan in tropical and subtropical seas. Eastern Pacific: Reported from Vancouver (Ref. 11980), from California (USA), Baja California (Mexico) to Chile, and the Galapagos Is. (Ref. 9068). Western Atlantic (Ref. 7251). Eastern Atlantic: Southeastern coasts of the Mediterranean and off Sicily; Reported from Cape Verde (Ref. 34514). Indian Ocean.

Length at first maturity / Size / Weight / Age

Maturity: Lm 45.0, range 40 - 50 cm
Max length : 96.0 cm WD male/unsexed; (Ref. 48844); common length : 80.0 cm WD male/unsexed; (Ref. 9254)

Short description Morphology | Morphometrics

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).

Biology     Glossary (e.g. 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 Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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).

Estimates based on models

Preferred temperature (Ref. 123201): 12 - 28.6, mean 24.8 °C (based on 5148 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00265 - 0.01571), b=3.06 (2.86 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.4   ±0.54 se; based on food items.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (K=0.18 (captivity); Fec=1-9 (could probably have 2 litters per year)).
Fishing Vulnerability (Ref. 59153):  High vulnerability (63 of 100).
Nutrients (Ref. 124155):  Calcium = 19.5 [4.9, 91.5] mg/100g; Iron = 0.96 [0.25, 2.71] mg/100g; Protein = 22.8 [19.9, 25.8] %; Omega3 = 0.354 [0.107, 1.041] g/100g; Selenium = 20.5 [5.9, 52.0] μg/100g; VitaminA = 15.6 [5.9, 43.5] μg/100g; Zinc = 0.475 [0.235, 0.879] mg/100g (wet weight);
