They attached a camera to a tiger shark and watched how it hunts

The researchers studied tiger sharks - Galeocerdo cuvier. They were first fished out of the sea west of Australia. After to

they were fitted with high-tech gadgets to understand their behavior.

On the body of each predator was an autonomous video camera, as well as a sensor that recorded all the shark's movements in 3D. The researchers then released them back into the sea.

The team reviewed all records and data thatmade by sharks. The most interesting was hunting for sea turtles. It was possible to take not only pictures of this process, but also to understand how the predator and prey moved during the attack.

“The video shows that the shark often swims nearturtles that sit on the reef, but from the point of view of a shark, a stationary turtle is not so easy to see,” said study leader Dr. Laura Ryan.

The authors noted that sharks are much easier to distinguishstand out clearly from the background of the turtles. As soon as the shark has spotted the prey, its behavior changes dramatically: it begins to move more slowly and dodge - so it is easier for it to understand what it is dealing with. At the same time, despite poor eyesight, the shark still relies on its own eyes.

Biologists concluded that tiger and otherpredatory sharks like it do not chase prey at maximum speed. Rather, they act slowly. This is in good agreement with the fact that the tiger shark is adapted to life in conditions of lack of food, which means that it saves energy and strength even when hunting.
