''Dysidea arenaria'' is a species of marine sponge (poriferan) found in the Pacific Ocean.〔 〕 It is a member of the order Dictyoceratida, one of two sponge orders that make up the keratose or "horny" sponges in which a mineral skeleton is absent and a skeleton of organic fibers is present instead. ==Description== A single specimen of this species was collected in Palau and described as the holotype specimen in 1965. A more recent description based on three specimens collected near Papua New Guinea highlights prominent conules and relatively infrequent oscules. The color was reported as "sand" in the field and "middle brown" after preservation, although the color of the preserved Palau specimen was given as "greyish-white".〔 Both descriptions emphasize the irregular, densely reticulated branch network.〔〔 Fibers made of sand, spicules, and spongin are also present, and aid in distinguishing the species from relatives.〔
