Elasmobranchii (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); armata: Latin for armed with a weapon, referring to heavy thorns on snout and between eyes, large hooked thorns on back, and enlarged thorns on leading edge of pectoral fins (See ETYFish).
More on author: Philippi.

Issue
This species is questionably a synonym of Squatina californica Ayres, 1859 in Eschmeyer (CofF ver. Jul. 2010: Ref. 84883) following various authors. Please send references, or more studies are needed.

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 (0.00295 - 0.01551), b=3.07 (2.88 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): High vulnerability (58 of 100).

Nutrients (Ref. 124155): Calcium = 17 [4, 86] mg/100g; Iron = 0.77 [0.20, 2.26] mg/100g; Protein = 19.6 [17.5, 21.5] %; Omega3 = 0.38 [0.17, 0.82] g/100g; Selenium = 27.1 [8.6, 81.5] μg/100g; VitaminA = 14.3 [4.6, 47.2] μg/100g; Zinc = 0.511 [0.248, 0.943] mg/100g (wet weight);
