- **Phylum:** Brachiopoda
- **Class:** Insecta
- **Order:** Coleoptera
- **Family:** Tenebrionidae
- **Genus:** Tenebrio

## Interesting facts

- Adult darkling beetles are champion crawlers, preferring walking to using their hidden wings!
- Scientists are even studying mealworms to see if they can help recycle plastic waste!
- Their babies are famous 'mealworms', often fed to pets like reptiles and birds!
- They are super tough and can live in very dry places where other insects struggle!

## Special abilities

- **Playing Possum Power:** Darkling Beetle can play dead by freezing still to trick predators into thinking they aren't worth eating, helping them escape danger.
- **Chemical Shield:** Darkling Beetle can release a foul-smelling chemical from its rear end to deter attackers, protecting itself from hungry creatures.
- **Decomposition Dynamos:** Darkling Beetle larvae (mealworms) have powerful jaws that help them break down dead plants, recycling nutrients back into the soil.
