Elasmobranchii (haaien en roggen) (sharks and rays) > Carcharhiniformes (Ground sharks) > Carcharhinidae (Requiem sharks)
Etymology: Carcharhinus: karcharos (Gr.), sharp or jagged; rhinus, an ancient name for sharks, from rhine (Gr.), rasp, both words alluding to a shark's jagged, rasp-like skin. (See ETYFish); isodon: iso-, from isos (Gr.), equal; odon (Gr.), tooth, allusion not explained, perhaps referring to how its teeth are similar in shape and size in both jaws [authorship often attributed to Müller & Henle, who published Valenciennes’ description]. (See ETYFish).

marien demersaal; diepte 0 - 20 m (Ref. 106604). Subtropical; 42°N - 38°S, 100°W - 12°W (Ref. 55182)

Western Atlantic: North Carolina, USA to Cuba, the Gulf of Mexico, and southern Brazil to Uruguay (Ref. 58839). Occurrence in the eastern Atlantic, specifically in Senegal and Guinea-Bissau, have not been confirmed and may be based on Carcharhinus brevipinna (Ref. 244, 127434).

Estimates based on models

Preferred temperature (Ref. 115969): 22.9 - 28.1, mean 27 (based on 617 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00479 (0.00221 - 0.01036), b=3.09 (2.92 - 3.26), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 4.2 ±0.7 se; based on diet studies.

Weerstandsvermogen (Ref. 120179): Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Fec=1).

Fishing Vulnerability (Ref. 59153): High vulnerability (60 of 100).
