A kayaker is lucky to be alive after being swallowed by a humpback whale off the coast of Chilean Patagonia and getting spit out by the leviathan.

A humpback whale briefly swallowed a 24-year-old kayaker last Saturday during a father-son excursion out on the icy waters around Chile’s southernmost Patagonia region.
