For many of us, sharks tend to be a source of fear.

But for Valerie Taylor, they've been a wonderful part of her life, with personalities as varied as puppies.

Valerie has swum with sharks all over the world, captured remarkable footage, and led conservation efforts to get us to rethink our relationship with these animals.

A new film, Valerie Taylor: Playing With Sharks, tells the story of Valerie's work and adventures.
