Talk about it
A diving beetle carries a bubble of air trapped by tiny water-repelling hairs. That structure works like a scuba tank, letting the beetle breathe below the surface.
- How does a diving beetle breathe while it's underwater?
- What holds the air bubble against the beetle's body?
- Why would being able to dive help a beetle find food or escape danger?
