There is no crevice on this planet that a spider cannot hide it seems.
Diving bell spiders (Argyroneta aquatica) are spiders who spend almost all of their time underwater. To do so they use their webs to capture a bubble of air full of oxygen. The web also functions similarly to a fish gill in that the web can draw in oxygen from the water itself. By spending most of it’s time underwater, the spider is more protected from many of its predators increasing its chances of survival.
I find it fascinating that there are so many species of spiders like the diving bell spider who have adapted so well into their environment. Whether its living underwater or preying upon birds spiders have shown resilient as well as flexible.
