These are the only two fish that have a long blade-like snout. [35] Although they are similar in appearances, saw sharks are distinct from sawfish. Sawfish are not sharks, but a type of ray. The gill slits of the sawfishes are positioned on the underside like a ray, but the gill slits of the saw shark are positioned on the side like a shark.

It has been referred to as a freshwater shark because of its heterocercal tail or caudal fin resembling that of sharks, though it is not closely related ...
Billfish have a long, bony, spear-shaped bill, sometimes called a snout, beak or rostrum. The swordfish has the longest bill, about one-third its body length.

The Chinese paddlefish had a white underbelly, and its back and head were grey. [7] Its dorsal and anal fins were situated considerably far back on the body. The paddle-like rostrum was narrow and pointed, and was between a quarter and up to a third of total body length. [8] Its eyes were small and round. [7]
Sawfish, also known as carpenter sharks, are a family of rays characterized by a long, narrow, flattened rostrum, or nose extension, lined with sharp transverse teeth, arranged in a way that resembles a saw. They are among the largest fish, with some species reaching lengths of about 7–7.6 m (23–25 ft). [1]
Marlins have elongated bodies, a spear-like snout or bill, and a long, rigid dorsal fin which extends forward to form a crest. Marlins are among the fastest marine swimmers. However, greatly exaggerated speeds are often claimed in popular literature, based on unreliable or outdated reports.
