The diving bell spider or water spider (Argyroneta aquatica) is the only species of spider known to live almost entirely under water. It is the only member of the genus Argyroneta . [ 6 ] When out of the water, the spider ranges in colour from mid to dark brown, although the hairs on the abdomen give it a dark grey, velvet -like appearance. [ 7 ]
Spider behavior refers to the range of behaviors and activities performed by spiders. Spiders are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom .

[5] The diving bell silk is "used for breathing," that is it serves to oxygenate the diving bell. [6]
Davis has published about 130 peer-reviewed articles and books, but the most important have focused on: 1) the development and use of animal-borne technology that has extended our understanding of the life history, behavior, ecology and evolutionary adaptations of aquatic animals at sea, 2) the morphological, physiological and metabolic ...
While the earliest chelicerates and the living Pycnogonida (if they are chelicerates [70]) and Xiphosura are marine animals that breathe dissolved oxygen, the vast majority of living species are air-breathers, [82] although a few spider species build "diving bell" webs that enable them to live under water.
