Elasmobranchii (Haie und Rochen) (sharks and rays) > Pristiophoriformes (Saw sharks) > Pristiophoridae (Saw sharks)
Etymology: Pristiophorus: pristio-, presumably derived from prio (Gr.), to saw, but treated here as a noun (a saw); phorus, from phoreus (Gr.), bearer or carrier, referring to saw-like snout (note also that pristis is Greek for sawfish). (See ETYFish); schroederi: Patronym not identified but almost certainly in honor of American ichthyologist William C. Schroeder (1895-1977), Woods Hole Oceanographic Institution (Falmouth, Massachusetts, USA), a world expert on chondrichthyan fishes. (See ETYFish).

Estimates based on models

Preferred temperature (Ref. 123201): 10 - 13.9, mean 12.6 °C (based on 12 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.6 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (52 of 100).
