The ant graveyard

"He's not dead, he's just... covered in oleic acid..."

Ants have graveyards where they take their dead. Apparently they do this for hygiene reasons :

But they don't take them there straight away, only after two days when the corpse starts giving off oleic acid. Ants marked with oleic acid are carted off to the graveyard even if they're not dead, but what's weird is that they don't seem to mind very much, and will even take themselves there unassisted. When the acid rubs off, normal services are resumed.
