Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Large ray with a huge, paddle-shaped caudal fin and with no papillae around spiracles. Shiny black or dark grey above, underside white (Ref. 5578). Broad subcircular disc, short snout anterior to the eyes. Smooth skin, short thick tail (Ref. 6902). Dark chocolate to purplish brown above, without spots, white below, but with edges of disc and pelvic fins of same hue as upper surface, tail with irregular dark margins (Ref. 6902).

Juveniles benthic over soft bottoms or near coral reefs (Ref. 12951) from 10-150 m; adults are semi-pelagic to pelagic, swimming in the water column and have been reported to migrate over long distances (Ref. 2803). Found on insular slopes to at least 925 m depth (Ref. 114953). Feeds mainly on pelagic and benthic bony fishes and small sharks (Ref. 5578). Ovoviviparous (Ref. 50449). Produces litters of up to 60 pups. In South Pacific region, males reaches maturity at ca. 60 cm TL (Ref. 114953). Packs a powerful electric shock of up to 220 volts (Ref. 9710).

Ciclo de vida ou comportamento de acasalamento Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | Larvas

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). With up to 60 in a litter. Gestation period one year (Ref. 12951). Size at birth about 23 cm (Ref. 12951).

Estimates based on models

Preferred temperature (Ref. 115969): 7.3 - 27.5, mean 13.9 (based on 3020 cells).

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01380 (0.01026 - 0.01858), b=2.99 (2.91 - 3.07), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Nível Trófico (Ref. 69278): 4.5 ±0.6 se; based on diet studies.

Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Fec=60;).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
