鋸鯊科 (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).
