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); varii: In honor of Richard P. Vari (1949-2016), National Museum of Natural History, Smithsonian Institution (Washington, D.C., USA), for his “outstanding” contributions to Neotropical ichthyology. (See ETYFish).

Short description Identification keys | Morphology | Morphometrics

This species is distinguished from all western Atlantic congeners (except S. david) by the following characters: a higher number of vertebral centra, 138-150 (vs. 132-136 in argentina; 128-136 in guggenheim; 127-136 in occulta; 130-135 in dumeril; 121 in Squatina sp. NW1); differs from all southwestern Atlantic species and S. david in their dorsal coloration, with very few (<20) or no white circular spots (vs. dorsal surface of the skin having hundreds of white spots in argentina, occulta, david, guggenheim) (Ref. 117896).

Occurs along continental slope (Ref. 114945).

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 (0.00293 - 0.01558), 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): 4.1 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (79 of 100).
