Elasmobranchii (hajar och rockor) (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).

Estimates based on models

Preferred temperature (Ref. 123201): 3.6 - 10.1, mean 6.7 °C (based on 250 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00176 - 0.00714), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  4.0   ±0.4 se; based on size and trophs of closest relatives
Resiliens (Ref. 120179):  Mycket låg, lägsta populationsfördubblingstid mer än 14 år (Fec assumed to be <10).
