## Interesting facts

- They have a specialized mouthpart called a radula, like a tiny ribbon of teeth, to scrape food.

## Special abilities

- **Stinging Cell Shield:** Aeolidia can store stinging cells from anemones it eats, using them for its own defense because of specialized digestive cells.
- **Taste Touchers:** Aeolidia has two feathery tentacles, called rhinophores, that help them "taste" the water and find their favorite food.
