Elasmobranchii (hajar och rockor) (sharks and rays) > Carcharhiniformes (Ground sharks) > Carcharhinidae (Requiem sharks)
Etymology: Rhizoprionodon: rhiza (Gr.), root; prion (Gr.) saw; odon (Gr.), tooth, referring to teeth with serrated (saw-like) bases, or roots [replacement name for Rhizoprion Ogilby 1915, preoccupied by Rhizoprion Jourdan 1861 in mammals]. (See ETYFish); longurio: Latin for a tall person, or a “slender youth or stripling” per Jordan & Evermann (1896), allusion not explained, perhaps referring to small, slim body of holotype (a male, presumably mature at 76.2 cm long), much smaller than its presumed congeners in Carcharias (original genus). (See ETYFish).

Estimates based on models

Preferred temperature (Ref. 123201): 18.1 - 28.7, mean 24.6 °C (based on 106 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00427 (0.00199 - 0.00915), b=3.11 (2.94 - 3.28), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.2 ±0.7 se; based on diet studies.

Resiliens (Ref. 120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Fec assumed to be <100).

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

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 14.1 [1.9, 80.3] mg/100g; Iron = 0.633 [0.168, 1.855] mg/100g; Protein = 21.5 [18.6, 23.7] %; Omega3 = 0.276 [0.118, 0.584] g/100g; Selenium = 20.7 [6.3, 61.3] μg/100g; VitaminA = 18.8 [6.6, 54.8] μg/100g; Zinc = 0.484 [0.228, 0.887] mg/100g (wet weight);
