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); argentina: Presumably named for Argentina, described from off the coast of Buenos Aires (the province, not the city). (See ETYFish).

Estimates based on models

Preferred temperature (Ref. 123201): 4 - 16.3, mean 6.1 °C (based on 18 cells).

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

Bayesian length-weight: a=0.00741 (0.00280 - 0.01965), b=3.04 (2.80 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.1 ±0.6 se; based on diet studies.

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Fec 7-11).

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

Climate Vulnerability (Ref. 125649): High to very high vulnerability (71 of 100).

Price category (Ref. 80766): High.

Nutrients (Ref. 124155): Calcium = 8.08 [1.10, 152.92] mg/100g ; Iron = 0.689 [0.065, 8.563] mg/100g ; Protein = 18.4 [16.3, 20.6] % ; Omega3 = 0.288 [0.108, 0.796] g/100g ; Selenium = 34.1 [6.7, 171.6] μg/100g ; VitaminA = 5.73 [0.45, 68.92] μg/100g ; Zinc = 0.355 [0.021, 4.093] mg/100g (wet weight);
