I really liked the biology of this spider. I also didn’t know there were spiders that lived underwater in the first place. The diving-bell spider makes webs underwater and these webs can hold oxygen. The interesting discovery from this article was that the oxygen bubble the spiders make could actually “replenish” its own oxygen supply by taking up oxygen from the surrounding water. Consequently, the spiders don’t need to go up to the surface and collect more oxygen as frequently. I thought it was really cool, and I didn’t know water/air bubbles could do that. Neato gang!
