Elasmobranchi (squali e razze) (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); lalandii: In honor of naturalist and explorer Pierre Antoine Delalande (1787-1823), who collected type [authorship often attributed to Müller & Henle, who published Valenciennes’ description]. (See ETYFish).

Length at first maturity / Size / Peso / Age

Maturity: L_m 61.8, range 58 - ? cm
Max length : 80.0 cm TL (female); common length : 55.0 cm TL maschio/sesso non determinato; (Ref. 5217); peso massimo pubblicato: 0.00 g

Inhabits shallow coastal waters, on sandy and muddy bottoms, and not normally found in lagoons and estuaries (Ref. 244). Feeds on small bony fishes, including sardines and anchovies, also shrimp and squid (Ref. 244). Viviparous, with 1 to 4 young in a litter; size at birth 33 to 34 cm (Ref. 244). Its flesh is highly appreciated and is marketed dried salted.

Estimates based on models

Preferred temperature (Ref. 123201): 24.6 - 28, mean 27.2 °C (based on 104 cells).

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

Bayesian length-weight: a=0.00269 (0.00177 - 0.00409), b=3.08 (2.96 - 3.20), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.65 se; based on food items.

Resilienza (Ref. 120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Fec=1).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (52 of 100).

Price category (Ref. 80766): Medium.
