How do sharks move when pursuing prey? Do they avoid other shark species?

[A] team of biologists from the Hawaii Institute of Marine Biology and the University of Tokyo’s Atmosphere and Ocean Research Institute decided to strap on a camera and see what happens.

[T]he researchers built a device that captures video and movement information (with a triaxial accelerometer-magnetometer like a flight-data recorder) but is small enough that it won’t interfere with a shark on the move.

They secure the camera to the shark’s fin, where it rides for up to two weeks. Then the device auto-releases and floats to the surface, pinging the research team for pickup.

Fortunately our species is good about producing adrenaline junkies, because there is no !@#? way in hell I would volunteer to strap a camera to the back of a shark.
