The Lynnwood family was out for a boat ride in the Puget Sound when three humpback whales swam underneath their boat. The family was boating near Lynnwood when they said the whales surfaced.

After the boat drove away, the boaters said the whales followed in their wake.

Ken Balcomb, executive director of the Center for Whale Research, told K5 News it’s not that common for humpbacks to swim under the boat like that, but if they do, they’re harmless and most likely want to play.

“Some individual humpbacks have a lot of curiosity and aren’t afraid of people,” Balcomb said.
