Elasmobranchii (haaien en roggen) (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.

50 = 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.
