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); nasutus: Latin for large-nosed, referring to its elongated snout. (See ETYFish).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00355 (0.00173 - 0.00727), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this Subfamily-BS (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.30 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Fec assumed to be <10).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (48 of 100).

Nutrients (Ref. 124155): Calcium = 8.92 [1.53, 55.68] mg/100g ; Iron = 0.366 [0.077, 1.297] mg/100g ; Protein = 16.6 [13.4, 19.7] % ; Omega3 = 0.184 [0.072, 0.455] g/100g ; Selenium = 14.1 [4.3, 47.2] μg/100g ; VitaminA = 12.2 [2.4, 62.5] μg/100g ; Zinc = 0.405 [0.191, 0.791] mg/100g (wet weight);
