Intertidal spiders: When Spiders take to the sea

[Gogyeng]

Desidae is a family of spiders (with genus Desis in particular) with that live in intertidal zones.
However, the genus Desis includes truly marine spiders commonly living in barnacle shells, which they seal up with silk. An example, Desis Bobmarleyi is a species found in the shores of north eastern Queensland. Australia. It is known to build air chambers from silk.

Do you know any other examples?

Weird, I wasn't aware of other members of that family besides Badumna. Super interesting that some are intertidal specialists. There's a niche for everyone!

Bewildered and confused. I have more than enough trouble just trying to grasp the animal life in an intertidal zone. Described as the most bio-active regions on the planet with fully aquatic and terrestrial animals, and everything in between, all claiming the zone as it's own biosphere. So mom nature tosses another ringer into the works in the form of spiders. It makes perfect sense in one way, an ultra target rich hunting environment while at the same time for a basically land based animal such as an arachnid, only slightly less hostile than the south pole.
To add something a little more bizarre, the rotting kelp on the beaches has a greater concentration of detritivorous animals than anywhere else on earth but is too hostile, transient, for arachnids to join in the feast.

I've enjoyed many leisure hours visiting this place: http://www.hsumarinelab.org/

Aw yay, I love Aussie spiders, for those that are interested we have several others that love a good day at the beach.
Have a look at the Australian Anyphaenidae, seashore spiders. These guys are right down in the spray zone on rocky shores but interesting enough is that anyphaedids are mainly based in South America. I used to get bored at the beach in about 5 minutes, that is until I found spiders there. I also find the U.Novahollandae scorpions fascinating as they inhabit beach dunes with ghost grabs, sort of like a crab with a sting.
Awesome link, I would like to know if any of the above have any special ways of dealing with excess salt.
