This amazing footage shows the brutal methods that orcas, also known as killer whales, use when hunting their prey.
The whales have been attacking sea lion pups in the Punta Norte Natural Reserve on the southern Argentine coast, displaying predatory hunting techniques.
The species is highly social, and pass hunting techniques down through generations.
They then work together to kill their prey.
As well as sea lions and killer whales, southern Argentina boasts a wide range of native fauna, including penguins.
