Summary
Museums keep colonies of dermestid beetles that gently clean every scrap of flesh off animal skeletons. Deep Look shows how these decomposers turn a dead animal into clean bones -- and recycle nutrients in nature.

Talk about it
Dermestid beetles eat away the soft parts of dead animals, leaving clean bones. In nature, decomposers like these return nutrients from dead bodies back to the ecosystem so life can reuse them.
- What do dermestid beetles eat, and why is that useful?
- How do decomposers help matter get recycled in nature?
- Why do museums keep these beetles on purpose?
