- **Kingdom:** Animalia
- **Phylum:** Arthropoda
- **Class:** Insecta
- **Order:** Coleoptera
- **Family:** Scarabaeidae
- **Genus:** Onthophagus

## Interesting facts

- Guano beetles are expert recyclers, turning animal droppings into rich soil nutrients.
- Some male Guano Beetles fight epic battles using their horns to win a mate!
- These beetles are super strong, able to pull loads over 1,000 times their own body weight!
- They play a crucial role in cave health by cleaning up waste and preventing diseases.

## Special abilities

- **Tunnel Master:** Guano Beetles can dig impressive tunnels underground because of their strong, spade-like legs, which helps them bury food quickly.
- **Night Navigator:** Guano Beetles have super-sensitive antennae that help them navigate and find food in complete darkness deep within caves.
- **Mighty Mover:** Guano Beetles can pull objects many times their own weight because of their powerful bodies, which helps them move large pieces of dung.
- **Scent Seeker:** Guano Beetles have an incredible sense of smell, able to detect the perfect food source from far away, even in complex environments.
