Western Indian Ocean: restricted to the Red Sea and the tropical western Indian Ocean to South Africa. Also reported from Persian Gulf (Ref. 68964). Apparently misidentified with closely related species in the northern and eastern Indian Ocean and western Pacific (however, Ref. 5978 seems to present a reliable record from western Indonesia).

Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

A large guitarfish with large black eyespots on the pectoral bases, a distinctive black cross between the eyes, and rows of small white spots on the upper body; snout pointed and lower caudal lobe short (Ref. 5578). Olive-green above, white below (Ref. 5578). Mouths small and contain flattened, pavement-like teeth.

Occurs inshore and in shallow estuaries (Ref. 5578). Feeds on crabs, lobsters, bivalves, small fishes (Ref. 5578) and squids (Ref. 37816). Ovoviviparous (Ref. 50449). Takes crayfish and pilchard bait. Meat and fins sought after in Asian markets (Ref. 30573).

Levenscyclus en paargedrag Maturities | Voortplanting | Spawnings | Egg(s) | Fecundities | Larven

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 4 young, about 43-60 cm in length (Ref. 37816), born in the summer (Ref. 3919).

Estimates based on models

Preferred temperature (Ref. 115969): 24.5 - 29.3, mean 27.1 (based on 304 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5049 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00372 (0.00166 - 0.00830), b=3.11 (2.91 - 3.31), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.6 ±0.6 se; based on diet studies.

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).

Prior r = 0.28, 95% CL = 0.18 - 0.42, Based on 1 data-limited stock assessment.
