Elasmobranchii 板鳃亚纲 (鲨鱼与 鱼) (sharks and rays) > Carcharhiniformes (Ground sharks) > Pentanchidae (Deepwater catsharks)
Etymology: Apristurus: a-, Latin privative, i.e., without; pristis, from pristes (Gr.), sawyer (but here meaning saw); oura (Gr.), tail, referring to absence of saw-toothed crest of enlarged dermal denticles along upper edge of caudal fin as found in the closely related Pristiurus (=Galeus) (See ETYFish); laurussonii: In honor of Saemundsson’s friend Gísli Lárusson (1865-1935), goldsmith, watchmaker, farmer and nature enthusiast, for his “long and invaluable support of the study of Icelandic fishes, and for carefully encouraging the skillful fishermen of Vestmannaeyjar Island [near type locality]” (translation) (See ETYFish).
Eponymy: Gísli Láurusson (1865–1935) was an Icelander described as ‘Hr Direktur’. [...] (Ref. 128868), visit book page.

基于模型的估算
首选温度 (参考文献 123201): 3.6 - 10.1, mean 6.7 °C (based on 250 cells).
系统发育多样性指数 (参考文献 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00172 - 0.00698), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (参考文献 69278): 4.0 ±0.6 se; based on diet studies.
回复力 (参考文献 120179): 非常低的, 最小族群倍增时间超过14 年 (Fec assumed to be <10).
营养素 (Ref. 124155): Calcium = 9.53 [1.72, 58.09] mg/100g; Iron = 0.338 [0.075, 1.163] mg/100g; Protein = 18.8 [16.7, 21.0] %; Omega3 = 0.234 [0.090, 0.612] g/100g; Selenium = 16.1 [4.9, 53.6] μg/100g; VitaminA = 6.11 [1.23, 28.29] μg/100g; Zinc = 0.296 [0.148, 0.550] mg/100g (wet weight);
