Western Indian Ocean: from South Africa to Zanzibar and possibly as far north as the Kenyan coast. (Ref. 83892). Possibly occurring off smaller islands in the Indian Ocean but identity of specimens uncertain and need verification (Ref. 5578). Found in estuaries in South Africa during periods of high salinity (Ref. 114953).

Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Large ray with a small caudal fin and small papillae around the spiracles (Ref. 5578). Dull grey above with variable markings, often in the form of dark lines or large spots; white below (Ref. 5578).

Inhabits estuaries and intertidal zone down to 439 m (Ref. 5578). Found in sandy areas near deep rocky reefs (Ref. 2712). Feeds on fishes and cuttlefish (Ref. 5578). Ovoviviparous (Ref. 50449). Large prey probably stunned by its powerful electric discharge (Ref. 5578). Young born in the summer (Ref. 5578). Common accidental catch of anglers (Ref. 114953).

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).

Estimates based on models

Preferred temperature (Ref. 115969): 12 - 25.8, mean 19.1 (based on 171 cells).

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01479 (0.00659 - 0.03318), b=2.97 (2.78 - 3.16), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 4.5 ±0.75 se; based on food items.

Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (46 of 100).
