Humpback whales visit the Salish Sea, the inland waters between B.C. and Washington state, during their migrations. Humpback whales were hunted to local extinction in these waters, but over the last 25 years, their numbers have recovered and are now routinely seen in whale-watching tours, McKeen said.

The West Coast is prime whale-watching territory, and the Pacific Northwest in particular is a perfect place to see some action unlike anywhere else on Earth. If you're lucky, you'll get more than the usual breaching show and watch as the ocean mammals hunt for their next meal,

Here's something you don't see every day: a seal in the mouth of a humpback whale.The incredibly rare event happened during a whale-watching tour.

A whale-watching naturalist photographed the seal in the whale's mouth after the giant marine mammal accidentally gulped it last Thursday

A humpback whale almost swallowed a seal off the coast of Washington. According to media reports, they were probably hunting the same swarm of fish where the whale caught it.
