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); terraenovae: terra (L.), earth or land; novus (L.), new, i.e., Newfoundland, Canada, where Richardson erroneously thought it occurred (See ETYFish).

Short description Chiavi di identificazione | Morfologia | Morfometria
Small, generally gray, streamlined shark, with long pointed snout. Posterior margin of anal fin straight or slightly concave. Second dorsal fin origin well behind anal fin origin (Ref. 26938).
Reaches at least 103 cm TL (Ref. 244). Abundant in the continental shelves, from the intertidal to deeper waters. Often occurs close to the surf zone off sandy beaches, and also enclosed bays, sounds, and harbors, in estuaries and river mouths. Feeds on small bony fishes, shrimps, crabs, segmented worms and mollusks (gastropod feet). Viviparous, with 1 to 7 young in a litter (Ref. 27549). Size at birth about 29 to 37 cm. Utilized for human consumption. Minimum depth from Ref. 055195.
Life cycle and mating behavior Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve
Distinct pairing with embrace (Ref. 205). Viviparous, placental (Ref. 50449). 1 to 7 young per litter. Larger females carry more young. Size at birth 29-37 cm. Gestation period is 10 to 11 months in the northern Gulf of Mexico. Sex ratio of near term fetuses is 1:1 (Ref. 244).

Estimates based on models
Preferred temperature (Ref. 123201): 23.4 - 28, mean 27 °C (based on 1016 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00274 - 0.00664), b=3.00 (2.87 - 3.13), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278): 4.4 ±0.5 se; based on diet studies.
Resilienza (Ref. 120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (K=0.19-0.45(?); tmax=10; tm=4; Fec 1-7).
Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100).
Climate Vulnerability (Ref. 125649): Very high vulnerability (85 of 100).
Nutrients (Ref. 124155): Calcium = 23.3 [2.5, 120.6] mg/100g; Iron = 0.89 [0.24, 2.75] mg/100g; Protein = 22.6 [19.7, 24.8] %; Omega3 = 0.372 [0.150, 0.861] g/100g; Selenium = 25.1 [6.4, 70.6] μg/100g; VitaminA = 8.35 [2.78, 24.50] μg/100g; Zinc = 0.452 [0.218, 0.855] mg/100g (wet weight); based on nutrient studies.
