A YouTube video by BBC Earth Unplugged shows what happens when beetles throw a breakfast, lunch, and dinner party inside both a John Dory and gunnard fish for three weeks.

The clip, recently shared by Sploid, stars dermestid beetles and larvae, the same hungry workers that are employed by some museums to clean the meat off of animal skeletons. The 12-millimeter-long beetles remove the skin from carcasses through a process called skeletonization.

In the video above, the beetles are first shown dining on the John Dory carcass and then the dermestids shift their focus to the gunnard. In both cases, all that's left at the end of three weeks is paper-thin skin and hollow bones.
