Elasmobranchii (hajar och rockor) (sharks and rays) > Squatiniformes (Angel sharks) > Squatinidae (Angel sharks)
Etymology: Squatina: Latin for skate, which angel sharks superficially resemble, presumably tautonymous with Squalus squatina Linnaeus 1758 (no species mentioned). (See ETYFish); dumeril: In honor of French zoologist André Marie Constant Duméril (1774-1860) “in testimony of [Lesueur’s] remembrance and esteem” (not in honor of Duméril’s equally famous zoologist son Auguste, born in 1812) [presumably a noun in apposition, without the patronymic “i”]. (See ETYFish).

Short description Bestämningsnycklar | Morfologi | Morfometri

A ray-shaped shark. Head narrowing to distinct neck at base of pectoral fins (Ref. 26938).

Occurs on the outer continental shelf and the upper slope. Found from shoreline to depths of 1,375 m (Ref. 26938).

Will bite when captured and can inflict nasty lacerations with its trap-like jaws and pointed teeth.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00402 - 0.01136), b=3.06 (2.91 - 3.21), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.5 ±0.6 se; based on diet studies.

Resiliens (Ref. 120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Price category (Ref. 80766): Medium.
