\Saw"fish`\, n. (Zo["o]l.)
Any one of several species of elasmobranch fishes of the
genus {Pristis}. They have a sharklike form, but are more
nearly allied to the rays. The flattened and much elongated
snout has a row of stout toothlike structures inserted along
each edge, forming a sawlike organ with which it mutilates or
kills its prey.
