Whale of an appetite: humpback almost swallows live seal in rare photo

Animal known as Big Mama' accidentally gulps marine mammal, who escapes in waters off Anacortes, Washington

A photograph by a whale-watching naturalist captured a seemingly bewildered seal in the mouth of a humpback whale after the giant marine mammal accidentally gulped it last Thursday in the waters off Anacortes, Washington.
