The diving bell spider or water spider, Argyroneta aquatica, is a spider which lives entirely under water.
Argyroneta aquatica is found in Northern and Central Europe and up to latitude 62°N and northern Asia. It is the only spider that spends its whole life under water. However it breathes air, which it traps in a bubble held by hairs on its abdomen and legs.[2]
