A marine biologist says the footage of the sharks hunting is the best his team has ever captured.
Footage shot from cameras attached to sharks has revealed how the animals charge through underwater forests to hunt for seals in areas previously thought to be inaccessible to the predators.
The seals have lower levels of the stress hormone cortisol. And Dyer Island is the only seal colony in South Africa where sharks appear in the daytime, said the authors of the new study published in the journal Biology Letters. It is believed this is because seals can hide from their attackers in the kelp.
Oliver Jewell, a marine scientist and PhD candidate at Murdoch University, told Newsweek: “It was previously assumed that kelp was a barrier to white sharks, and it's only through these relatively newly developed tags that we were able to observe it is not. It's a great example of how technology is being used to change our perspectives on the behaviors of wildlife."
“Our team have used these methods on white sharks at locations across the world but this remains some of the best footage we've ever captured.”
