The diving bell spider, or water spider, is the only species of spider known to live almost entirely under water. The water spider traps air bubbles in hydrophobic hairs on its abdomen and legs. Then it builds an underwater air bubble nest among waterweed. The water spider can mate, lay eggs, rest and dine in the air bubble nest. It can reside in the nest for two days before coming out of the water again.
