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

Marine; demersal; depth range 12 - 65 m (Ref. 4438). Tropical; 37°N - 36°S, 18°W - 35°E

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

Eastern Atlantic and Mediterranean Sea: Central to South Eastern Atlantic: Morocco, Mauritania to Congo (Ref. 33465) to Natal, South Africa (Ref. 5578); Mediterranean Sea: the records are patchy along the northern coast of Africa, and in Aegean Sea and Levantine Basin, most likely due to misidentification with other Dasyatidae spp. (Ref. 122045 and others cited).

Maturity: Lm ?  range ? - ? cm
Max length : 74.5 cm TL male/unsexed; (Ref. 123700)

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0. Conspicuous bright blue blotches and branching lines on a golden brown disc; snout and disc angular, and tail less than twice body length with a short upper caudal finfold, and a longer lower one falling far in front of tail tip; disc without thorns; usually one sting (Ref. 5578). Underside white, tail darker and without bands (Ref. 5578).

Biology     Glossary (e.g. epibenthic)

Close inshore, found on sandy beaches and in shallow bays (Ref. 5578), sometimes near rocky reefs (Ref. 12951). Found in deeper offshore areas during the winter season (Ref. 12951). Feeds on crabs, mantis shrimps, amphipods, worms, and fishes (Ref. 12951). Ovoviviparous (Ref. 50449). Minimum depth reported from Ref. 4438. Disc width measures 30 cm. Its thorny, venomous hooks can cause painful injuries (Ref. 5377).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | 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). With 1 to 4 in a litter (Ref. 12951). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 20.6 - 28.1, mean 26.3 °C (based on 164 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5002   [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):  3.6   ±0.53 se; based on food items.
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (Fec=1-4).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (50 of 100).
