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

marino; salmastro associati a barriera corallina; distribuzione batimetrica 0 - 439 m (Ref. 11228), usually ? - 50 m (Ref. 114953). Tropical; 2°S - 35°S, 17°E - 59°E (Ref. 114953)

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).

Maturity: L_m ? range ? - ? cm
Max length : 64.0 cm TL maschio/sesso non determinato; (Ref. 2712)

Short description Chiavi di identificazione | 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).

Life cycle and mating behavior Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve

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).

Phylogenetic diversity index (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).

Trophic level (Ref. 69278): 4.5 ±0.75 se; based on food items.

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Preliminary K or Fecundity.).

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