Saw Shark (underneath view). The sawsharks or saw sharks are an order (Pristiophoriformes) of sharks bearing long blade-like snouts edged with teeth, which they use to slash and disable their prey. Most occur in waters from South Africa to Australia and Japan, at depths of 40 metres (130 ft) and below; in 1960 the Bahamas sawshark was discovered in the deeper waters (640 m to 915 m) of the northwestern Caribbean.
If there were a shark Olympics, these sharks would be gold medalists. They may not be judged like your typical athletes, but researchers have a variety of machines and experiments to measure a shark's size, strength and performance.
