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); pseudocellata: pseudo-, from pseudes (Gr.), false; ocellata (L.), having little eyes (ocelli), referring to indistinct ocellate markings on pectoral fins (See ETYFish).

Short description Identification keys | Morphology | Morphometrics

Body strongly depressed anteriorly, firm. Trunk strongly depressed, almost ray-like, deepest over abdomen; not tapering abruptly at pelvic-fin insertion, tail strongly depressed, even at origin of caudal fin. Abdomen moderately elongate. Head broad, extended laterally, strongly depressed. Dermal denticles covering entire dorsal surface of body; less dense, absent on posterior borders of fins (Ref. 74939).

Estimates based on models

Preferred temperature (Ref. 123201): 14.1 - 20.4, mean 18.9 °C (based on 8 cells).

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): 3.9 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary low fecundity).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100).
