    • n Sawfish (Zoöl) 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.

Century Dictionary and Cyclopedia
    • n sawfish An elasmobranchiate or selachian fish of the family Pristidæ, having the snout prolonged into a flat saw or serra beset on each side with horizontal teeth pointing sidewise. The body is elongate like that of a shark, but is depressed, and the branchial apertures are inferior. The first dorsal is opposite or a little back of the bases of the ventrals. Five or six species of the genus are known; they are chiefly inhabitants of the tropical oceans, but occasionally wander beyond their ordinary limits. The European species is Pristis antiquorum, the pristis of the ancients, of the Atlantic Ocean, attaining a length of from 10 to 20 feet, and of a grayish color. The common American saw-fish is Pristis pectinatus. The saw attains a length of a yard or more, and is straight, flat, a few inches wide, obtuse at the end, and furnished in the European species with from sixteen to twenty pairs, and in the American with from twenty-four to thirty-two pairs of stout sharp teeth, firmly implanted at some distance apart; it is used as a weapon of offense and defense, especially in killing prey. See also cut under Pristis.
    • n sawfish Hence also By extension, one of the different selachians of the family Pristiophoridæ, 337 having a similar saw-like appendage, which never reaches such a size as in the Pristidæ, or true saw-fishes. They are confined to the Pacific. See cut under Pristiophorus.
