"Floating Robot Helps Track Great White Sharks"

"A floating robot has been deployed to track great white sharks in the Pacific as part of efforts to understand the giant predators."

"The 'wave glider', which from above looks like a yellow surfboard, picks up signals from tagged fish up to 1,000 feet away in the ocean and then sends their positions to researchers via a satellite transmitter.

Scientists have only a hazy understanding of where great white sharks, portrayed as ferocious killers in films like 'Jaws', swim in the oceans. The new robot will give insights into their movements."
