WATCH: Mysterious bubbling turns out to be whales fishing

Visitors to a lodge in British Columbia in Canada were awestruck by the spectacle of humpback whales creating circles of bubbles to catch fish.

First a ring of bubbles appeared on the surface of the water, and then in a magical moment a pod of whales surfaced all at once.

The breathtaking moment was caught on camera by a quick-thinking visitor.
