Install a super-sensitive camera on the shark's body

Scientists can now track shark activity by attaching cameras to their dorsal fins.

The study, by researchers from the University of Hawaii (USA) and Tokyo (Japan), is the first project to use complex sensors and video-recording equipment to track how fish work. fat in the sea environment.

"Our goal is to find information that is not known about the role of sharks in the oceans, " said National Geographic magazine quoted Carl Meyer of the University of Hawaii.

One camera recorded a moving shark at a depth of 91m before joining a shark union, shark fins and hammerhead sharks.

In one scene, shark experts use the power to swim through the ocean to move across the ocean rather than relying on the flow.

While shark tracking projects have been underway for many years, this is the first project to use a super-responsive device that produces 3D models of shark movement and energy levels. when swimming.

Accordingly, accelerometers and magnetometers can determine the swimming speed of the fish as well as the magnetic field around it, while others measure the depth and temperature of the water.
