Housemates can be a annoying at times, but thankfully, most house feuds don't end up in one mate eating another, as was the unfortunate case between these two sharks.

Visitors were shocked at the COEX Aquarium in Seoul, South Korea as an 8-year-old female (2.2 m) sand tiger shark made an easy meal of its tank mate, which is a 5-year-old male banded hound shark, half its length.

The whole thing took around 21 hours to complete, and has been described by aquarium staff as a "turf war.”
