| Summary: | Sharks may be famous for their reputation as villains of the sea, but there are still many things about them that we do not understand. Shark expert Dr. Mike Heithaus uses the CRITTERCAM, an underwater research tool, to answer questions about the foraging techniques, social behavior and migratory patterns of three of the superstar species: hammerhead, tiger and bull sharks. Did evolution produce the hammerhead's bizarre hammer? Why do tiger sharks seem to eat anything that moves-and even some things that don't? How do bull sharks-"the pit bulls of the sea"--Thrive in both fresh and saltwater? Join Mike as he travels to the Florida Keys in pursuit of these predators. |
