Great Hammerhead Invasion

Shark Week's Dr. Tristan Guttridge tags and follows giant hammerhead sharks to find out what brings them to Bimini in the Bahamas in early November. Many appear to be pregnant females and Dr. Guttridge has found evidence they've arrived to feed the growing young in their bellies before moving to the Florida coast to prey on migrating blacktips.
