Élasmobranches (requins et raies) (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); taylori: In honor of entomologist Frank Henry Taylor (1886-1945), Institute of Tropical Medicine, Townsville, North Queensland, Australia, who collected holotype. (See ETYFish).

Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 0; Épines anales 0; Rayons mous anaux: 0. Brownish grey above, white below, fins light-edged but not conspicuously marked (Ref. 9997).

A little-known shark (Ref. 9997) found on the continental shelf from close inshore to a depth of at least 110 m (Ref. 6871). Feeds mainly on fishes, but also takes cephalopods and crustaceans (Ref. 6871). Viviparous (Ref. 50449). Caught frequently by inshore demersal gillnet fisheries off Papua, but rarely elsewhere. Utilized for its fins and meat (Ref.58048). Too small to be of any commercial importance (Ref. 6871).

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Viviparous, with a yolk-sac placenta (Ref. 9997) and 1-10 pups after a gestation period of 11-12 months; born at ~ 25 cm TL; very rapid growth (Ref.58048). Distinct pairing with embrace (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 22.5 - 28, mean 26.6 °C (based on 321 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).

Niveau trophique (Ref. 69278): 4.5 ±0.0 se; based on diet studies.

Generation time: 2.6 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (K=1.01-1.34; tm=1; tmax=7; Fec=1-8).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (33 of 100).
