From this article: https://arstechnica.com/science/2024/04/swimming-and-spinning-aquatic-spiders-use-slick-survival-strategies/

Spiders already possess some adaptations that help in the water, such as hairs that repel water and trap air around them (a).

The diving bell spider Argyroneta aquatica uses these hairs to transport a large volume of air to its underwater canopy (b).

Other spiders burrow under the sand and surround their nests with waterproof silken barriers to stay safe when the tide is high ©.

Desis marina builds its own watertight silk nest in the holdfast where bull kelp attaches to rocks (d).

Other spiders, such as Marpissa marina, build their waterproof nests inside old seashells (e).

    I don’t like this guide. It’s cool and informative, but hard to follow.

      Yea it’s more of a figure that I stole from the article than a proper guide. I’ll add the caption which had more context for the figure

      Thw first picture is kind of informative. After that there is a severe lack of information.

      I also fail to see how nesting in a shell or general burrowing are “adaptations to aqautic life”. Especially the last one is just a spider nesting a secluded space that happen to have some aquatic origin. The last 3 pictures are basicially just “waterproof silk”.

    The ones that adapt well enough will eventually have their offspring served up at Red Lobster. If Red Lobster is still around in a few hundred thousand years.
