Cameras attached to sharks in South Africa reveal 'spectacular' images


Scientists have paired cameras with white sharks to reveal unparalleled hunting tactics in densely populated kelp forests.

Images of eight sharks off the South African coast show that predators are able to navigate through tight forests.

Researchers, including Oliver Jewell, a Ph.D. student at Murdoch University, have safely secured cameras and motion sensors to sharks, designed to stay in place for a defined number of hours, before they can be collected. on the surface.

Previously, it was thought that white sharks were too big to enter the kelp forests, rather hunting at the edge.

Mr. Jewell told Murdoch University: "The film we collected gives us a new perspective on this species.

"We can see how they interact with their environment in real time, and they are able to make spectacular 180-degree turns in the kelp forest.

"In the past, you had to guess. We would track the sharks up to the edge of the kelp forest, but we would lose the signal. "

The research, a collaboration between the University of Murdoch, the Monterey Bay Aquarium and Stanford University, was published in the journal Biology Letters.
