Park ranger feels peace among killer whales

Killer whales are ferocious predators but park ranger Roberto Bubas feels a profound peace in close encounters with the enormous creatures.

The 37-year-old from Puerto Madryn, in southern Argentina, said he watched and photographed orcas from the shore for years before he felt them calling to him and waded into the ocean to touch them.

"When you get close to these animals it inspires calm, peace," said Bubas, who has been filmed and photographed clapping his hands on the sea to attract the killer whales.
