Shark Week - Season 26 (1987)

Researchers follow-up on two great white shark males that are believed to be brothers. Never before have great whites been seen to associate, and the team works at the Isle of Jaws off Western Australia to find answers.

Scientists believe that monster sharks make their home under the Old Seven Mile Bridge. Fishermen claim that one of the sharks is a 18-foot long, one-ton great hammerhead named Big Moe. If this is true, he will be the largest hammerhead on the planet.
