I can't think of anything I regret. Everything I've done, I've enjoyed doing. I've had five husbands, four children. I've done it all, but mainly I've enjoyed studying fish and being underwater with them, being in their natural habitat, looking at the fish and the fish looking at me.

I want to be remembered as a nice person who didn't hurt people - except my ex-husbands, maybe.

As a child, William Beebe was my hero, and I used to read about him going down in the bathysphere, and I wanted to do that too. And I told my family, I said, 'I'd like to go down and be like William Beebe,' and they said, 'Well, maybe you can take up typing and get to be the secretary of William Beebe or somebody like him.'

Sharks are among the most perfectly constructed creatures in nature. Some forms have survived for two hundred million years.
