Desis is a genus of intertidal spiders that was first described by Charles Athanase Walckenaer in 1837.[2] It is found in Australasia, the Pacific, Japan, eastern and southern Africa, and India. They are truly marine spiders, living in the intertidal zone and only emerging at night on the ebb tide to hunt for invertebrates and small fish. In the day and during high tides, they hide in an air chamber sealed with silk.[3][4][5]
