This is what it’s like to nearly get eaten by a whale
So what would happen if a humpback whale did try to eat you? According to NOAA, baleen whales have small throats about the size of basketballs. So they certainly couldn’t swallow a human. But they do have powerful tongues and the overall experience might not be too pleasant.
Relatedly, here’s a long Salon essay from 2012 in which Ben Shattuck tries to find a record of any whale ever swallowing a human. (Sperm whales, with their sharp, 8-inch teeth, seem like one possible candidate.) He comes up empty, but it’s an entertaining read all the same.
