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);  delicatus: Latin for dainty or delicate, referring to fine, delicate rostral teeth on elongated rostrum. (See ETYFish).
