38 genera, 182 species

The intertidal spiders (family Desidae) are named for the genus Desis, members of which live in a very unusual location — between the tides. The family has been reevaluated in recent years and now includes inland genera and species as well, such as Badumna and Phryganoporus. Those intertidal spiders that are truly marine commonly live in barnacle shells, which they seal up with silk; this allows them to maintain an air bubble during high tide. They emerge at night to feed on various small arthropods that live in the intertidal zone.


As of January 2016, the World Spider Catalog accepted the following genera:[1]
