Dung Beetles are a whole host of beetles who feed partly or entirely on faeces.
One particular species is Scarabaeus sacer, the Sacred Scarab. It belongs to the subfamily Scarabaeinae, which is in the family Scarabaeidae, itself in the superfamily Scarabaeoidea. So while some Scarabs are quite pretty and feed on flowers and nectar, they're still named after a plain, black poo-feeder. All must live in the shadow of a massive ball of faeces and they shall never escape it. That has got to be psychologically problematic.

Whoa, man! Don't touch it, you know exactly where it's been!
Even when it comes to dung, Dung Beetles prefer the produce of herbivores and turn their stink-resistant noses up at carnivore-plop. So... they're vegans?

Another strategy is to bury it where it stands. This secures it from the attentions of rival Dung Beetles and... all those other creatures that like their food pre-digested. The problem here is that lots of perfectly good waste products may go to waste simply because it landed on ground the beetle can't dig into. Hmmm...
Balls! Of course! When it comes to faeces, you know the question is peculiar when the answer involves rolling it up into a ball. But that's what a lot of Dung Beetles do.

But adult Dung Beetles don't always horde all this dung for themselves. It also works as unusually disgusting baby food.
This time, a pair of Dung Beetles choose some particularly fine-textured dung that won't cause problems for delicate, grub-tummies.

Once the ball is safely buried beneath the earth, the female lays her eggs. Sometimes the pair will then immediately leave, perhaps to get a whole new ball and lay some more eggs, other times they'll guard their burrow.
