Perfect Predators Shark Week : Season 2007 Episode 5

During more than 400 million years of evolution, over 400 species of shark have developed highly refined instincts and abilities to keep them the ocean’s top predator. This premiere program observes sharks in their environment in oceans around the globe, including tracking the migration of a baby shark in Bimini, attaching cameras to the social lemon shark to see how they relate to one another, and investigating a newly discovered great white behavior. Some great whites have been tracked migrating from the West Coast of the United States to a blank spot on the map in the mid-Pacific at the same time every year – but why? Also investigated are new scientific applications and technologies being developed using the unique properties of shark skin – from mimicking its barnacle-shedding properties on the outer side of ships, to its bacteria-resistant properties to coat medical applications such as operating tables and catheter tubes.
