Watch: Killer whales spotted off coast of Monterey Bay

MONTEREY, Calif. - In a stunning sight in Monterey Bay, killer whales were spotted off the coast on Friday.

Caught on camera, the captain of Sanctuary Cruises in Moss Landing shared video with KTVU showing dozens of killer whales swimming. 

He called it a "once in a lifetime" encounter.

The captain estimated there were roughly 80 whales in the Bay on Friday and said these whales are only seen once in the bay every five years, towards the end of the Orca season.
