What body covering does the water spider have?

The water spider, also known as Argyroneta aquatica, has a unique body covering that is primarily composed of a waxy layer, which helps to repel water. This adaptation allows it to maintain air bubbles on its body, enabling it to breathe underwater. Additionally, its body is covered in fine hairs that trap air, enhancing its buoyancy and allowing it to hunt and live submerged in aquatic environments.
