A plain eagleray with a short, rounded snout; disc with broadly angular corners, and upper or lower jaw usually with 7 rows of plate-like teeth (Ref. 5578). Brown or blackish dorsally, white ventrally (Ref. 5578). No caudal fin (Ref. 5578).

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

Eastern Atlantic: Madeira, Morocco and the Canary Islands north to the western coasts of Ireland and British Isles and the southwestern North Sea, south to Natal, South Africa. Also throughout the Mediterranean.

Biology     Glossary (e.g. epibenthic)

Found in shallow lagoons (Ref. 3965), bays and estuaries; also offshore down to at least 95 m (Ref. 5578). Often found in groups (Ref. 5578). Feeds on benthic crustaceans, mollusks and fish. Ovoviviparous (Ref. 50449). Gestation period of 6-8 months, the females give birth to 3-7 young (Ref. 35388). Caught by shore and ski-boat anglers, usually released after capture (Ref. 5578). Flesh is highly esteemed (Ref. 3965).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | 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).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00119 - 0.01213), b=3.08 (2.82 - 3.34), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.54 se; Based on food items.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Fec=3).
Vulnerability (Ref. 59153):  Very high vulnerability (83 of 100) .
Price category (Ref. 80766):   High.
