Sharks' underwater world revealed

In an attempt to learn more about the behaviors of sharks, researchers from the University of Hawaii and University of Tokyo outfitted a variety of sharks with cameras and sensors to learn more about how the predatory fishes spend their time.

The equipment offers a "sharks-eye view" into a little understood world, with video providing a rare glimpse at what sharks see, and an array of sophisticated sensors measuring where sharks are going and how they are getting there.

"What we are doing is really trying to fill out the detail of what their role is in the ocean," said Carl Meyer, an assistant researcher at the Hawaii Institute of Marine Biology at the University of Hawaii at Manoa. "It is all about getting a much deeper understanding of sharks' ecological role in the ocean, which is important to the health of the ocean and, by extension, to our own well-being."
