A shark can pick up soundwaves over 5km and home in on the source to within a square metre, even in zero visibility. It can smell blood in the water at 8km, detect increased electrical current in the bodies of wounded fish or panicking humans, even hear their heartbeats. It can move at 60kmph-plus. It has no dental problems - if a tooth breaks off the next automatically takes its place. Such features make the shark the consummate predator, but it uses them only for survival.
Sharks have more to fear from man than vice verse.
We are slaughtering these creatures at the frenzied rate of 100 million a year. Shark fins command high prices. Even in Europe shark's fin soup is eaten. The barbarity of the methods used in obtaining the fins can hardly be surpassed. They are cut from the living creatures, which are then tossed back in the water.
