A spider builds a room full of air below the surface
The diving bell spider constructs an underwater web chamber and carries air to it using water-repellent hairs on its body. The chamber serves activities such as feeding, and females also raise young there. Its underwater lifestyle still relies on air rather than fish-like gills.
