The king of the swimmers, and proof that you can deal with a huge shark if you have the knowledge...

What makes us humans human? Well it certainly isn't the ability to do the breaststroke, as these apes have learned it from humans caring for them:

 

Renato Bender, a primate researcher at a Johannesberg univeisty, has videoed two chimps swimming, diving, and generally having a good time in the water.
