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).
Eponymy: Frank Henry Taylor (1886–1945) was an entomologist at the Institute of Tropical Medicine, Townsville, Queensland, Australia. [...] (Ref. 128868), visit book page.

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).
所知极少的鲨鱼 (参考文献 9997) 发现于大陆架从岸边到深度至少 110 公尺了。 (参考文献 6871) 主要吃鱼, 也捕食头足类动物与甲壳动物.(参考文献 6871) 胎生的.(参考文献 50449) 太小以致于没有任何的商业重要性.(参考文献 6871)

Estimates based on models
Preferred temperature (Ref.
123201): 22.5 - 28, mean 26.6 °C (based on 321 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00202 - 0.00902), b=3.10 (2.93 - 3.27), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
营养阶层 (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.
回复力 (Ref.
120179): 非常低的, 最小族群倍增时间超过14 年 (K=1.01-1.34; tm=1; tmax=7; Fec=1-8).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (33 of 100).
