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); nudipinnis: nudus (L.), bare or naked; pinnis (L.), fins, referring to most of dorsal fins and upper sides of pectoral fins being scaleless (See ETYFish).
