Sawfish

Sawfish, any fish of the genus Pristis, with five species from tropical and sub-tropical seas. They belong to the saine group as the Rays, and have the snout produced into a flat blade-like form (sometimes six feet long and a foot broad at the base), and armed at the side with projecting teeth. The true teeth are small; but with its "saw" the fish tears off flesh from its prey (often large cetaceans), or rips open the abdomen and devours the soft parts. The skin is used for polishing.
