Explorer - Shark Superhighway

Seizoen: 2008 - Aflevering: 5 / 365 - Eerst uitgezonden: 08 april 2008 - Episode ID: 563763

Sharks have thrived in the oceans for over 350 million years, but around 20 million years ago a new species emerged in the fossil records in a form unlike ever seen before... the Hammerhead Shark. Why did this bizarre looking creature evolve was it a need for greater maneuverability, a need for a more advanced sensory system or was it a genetic mistake? And how has the Hammerhead continued to survive? Scientific evidence suggests that Hammerheads seek out distant destinations but what prompts them to travel these great lengths? How do they navigate? Do they possess an internal compass? Do they possess a map? Dr. Pete Klimley is seeking to answer these questions and discover how Hammerheads live and survive across the turbulent seas by mapping their underwater movements. In a world threatened by over fishing and declining populations the Hammerhead Highway may be the key to understanding and ensuring the Hammerheads survival.
