I have to fight the urge not to reach out and pet the giant torpedo-like animals. What I learn about sharks is also true about Doc. Once you get to know him, you realize he may live on the edge, but he never crosses over it. He knows these sharks better than just about anybody else in the world. I've been doing this for nearly 40 years and no one's ever been hurt out here.
Reef sharks circle the chum area.
Doc Gruber has increased our knowledge of sharks immeasurably. He studied the eyes of lemons and found they could see color. He found that, not only aren't lemon sharks eating machines, they eat very little and infrequently because their digestive process is slow. He found that they're very smart. Not only do they learn, but they remember.
