| | | water spider system
hello everyone...im an architecture student and desperately looking for the system of a water spider, argyroneta aquatica...i cant find anything scientifically on how the spider captures the air bubbles filled with oxygen and how it produces this diving bell underwater. I have found many images, but not much helpful.Being an architect,we have to derive ideas on how the spiders system works, how it creates it in every detail and i am quite lost since i cant find any sources!!!!pleaseeee,if anyone has any book on mind or where i can look i would really appreciate it.This bio natural investigation is all new to me, so im quite stressed.anyway,txs for whoever answers me... |

Argyroneta aquatica has several features such as abdomen and legs being densely covered in short hairs that trap air when the spider is submerged.
They spin underwater webs amongst the weeds they fill these with air by travelling upto the surface and returning to the web in the weeds, carrying air bubbles around the body. As the web fill's with air, it become's bell-shaped and take's on a silvery appearance. |

Also due to the bell being underwater oxygen defuses into it, and carbon dioxide out of it meaning it requires little maintenance  . |
