Definition of "sawfish"

The sawlike snout that gives the sawfish its common name may represent up to one-third of its total body length. Despite its sharklike shape, the sawfish is more closely related to rays.

Because of their sharklike appearance, people often refer to the sawfishes as sharks. However, they are actually related to the skates and rays because the gills are ventral, the eyes are on top of the head, and the pectoral fins are attached to the head.
