An 8-year-old female shark spent nearly 21 hours eating a 5-year-old male shark. Why? Apparently he bumped into her space one time too many.

The sharks live in an aquarium in Seoul, and the tank normally contains many sea creatures living in harmony. According to Reuters, "Sharks have their own territories, this aquarium official said. Sometimes when they bump into each other, they bite out of astonishment." This female shark must've been really surprised, because she not only bit the male shark, but also proceeded to eat him head first.

Unfortunately, the female shark won't be able to digest the male, and she's expected to regurgitate him after a few days. Probably could've been avoided if she ate him with some fava beans and a nice chianti.
