A group of men recording off a Canada shore were left astonished after they witnessed several killer whales swim close to shore and rub themselves on the beach.

"Holy moly!" one of the individuals said in the video posted late last month. "This is crazy! It probably feels like a nice massage."

"Jesus!" one person could also be heard saying.

The Orca Network shared the video on Facebook, calling the footage "stunning."

"Absolutely remarkable footage of northern resident orca with their culturally unique behavior of rubbing themselves on beaches like this," expert Jackie Hildering said.

At the time of publication, the footage had amassed just over 150,000 views on YouTube.
