Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

A large devil ray with a long head bearing short head fins; dorsal fin plain, and pectoral fins with strongly curved, swept-back tips; upper disc densely covered with small, pointed denticles and tail shorter than disc with no spine (Ref. 5578). Dark blue (Ref. 5578), olive-green to brownish above; ventral side white anteriorly, grey posteriorly, with an irregular but distinct line of demarcation (Ref. 11228). No caudal fin (Ref. 5578).

Mostly oceanic, but also in coastal waters. Solitary, sometimes forms groups (Ref. 12951). Feeds on small fishes (Ref. 5578) and planktonic crustaceans (Ref. 9911). Ovoviviparous (Ref. 50449). Litter number 1 (Ref. 12951). Sometimes found stranded in beaches in temperate areas (Ref. 9911). Data on female Max. length from Ref.9256. Commonly caught in tuna gillnet and in harpoon fisheries. Utilized for its gill filter plates (very high value),meat, cartilage and skin (Ref.58048).

Life cycle and mating behavior Maturities | Fortpflanzung | 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).

Estimates based on models

Preferred temperature (Ref. 115969): 19.4 - 28.9, mean 27.1 (based on 1824 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.59 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Fec=1).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (85 of 100).

Preiskategorie (Ref. 80766): Medium.
