However, perhaps no creature was wiped from the face of the planet for as silly a reason as the great auk. Once endemic to the North Atlantic, the great auk was a flightless seabird not too dissimilar in appearance from a penguin. This, in turn, caused sailors to hunt the few remaining great auks in existence with a renewed zeal. The sailors, under orders from a merchant who wanted a pair of great auk pelts for display, found the birds nesting on a rock. Then, for no particular reason other than “screw the great auk” we guess, Ketilsson then stomped the birds’ nest a few times to destroy the egg they’d been incubating.
