Elasmobranchii (sharks and rays) > Lamniformes (Mackerel sharks) > Carchariidae (Ragged-tooth sharks)
Etymology: Carcharias: From the Ancient Greek karkharías, shark, derived from kárkharos, sharp or jagged, referring to a shark’s teeth (See ETYFish); tricuspidatus: -atus (L.), provided with: tricuspid teeth, referring to how “awl-shaped” teeth have a “small basal cusp” (or cusplet) on both sides of smooth main cusp [perhaps a junior synonym of C. taurus] (See ETYFish).
More on author: Day.

Issue
Questionably a synonym of Carcharias taurus (Ref. 35766, 43278). Questionably a synonym of Carcharias taurus Rafinesque 1810 (Compagno 2001:58; Ref. 43278). Probably a junior synonym of Carcharias taurus, thus, regarded as a doubtfu

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.8125   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00267 - 0.01964), b=2.99 (2.77 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.4   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
Price category (Ref. 80766):   Unknown.
