Anderson, who operates Captain Dave’s Dolphin and Whale Safari, says the last time he saw a pod of orcas as big was on Valentine’s Day in 2005.

Gray whales are often spotted between January and April off the coast of Southern California. Blue whales travel through the area from June through October. Dolphins are seen year-round.

Anderson says Thursday’s sighting is one of the best he’s ever seen.
