1938 , Robert William Pennak , The ecology of the psammolittoral organisms of some Wisconsin lakes, with special reference to the tardigrada, copepoda, and rotatoria, Thus, with the exception of the narrower beaches, and Michigan and Pallette, the psammobiotic rotifers were concentrated at the edge or beyond the area of saturation on the beaches.
2007 , Victor Fet & ‎Alexi Popov , Biogeography and Ecology of Bulgaria , A total of 47 interstitial testate amoebas have been recorded in the Bulgarian Black Sea coast. Of these, 32 are psammobiotic, 11 are psammophilic, and 4 are psammoxenic.
2008 , Olav Giere , Meiobenthology: The Microscopic Motile Fauna of Aquatic Sediments, The psammobiotic species are usually particularly small (mostly around 50 μm), and the shell is often flattened.
2012 , Koen Martens , Aquatic Biodiversity: A Celebratory Volume in Honour of Henri J. Dumont, The North American endemic Trichocerca are remarkable. This group contains nine species (13.4% of Trichocera; Table 3), all of which have been found on several occasions. Of these, only one is psammobiotic, thus inhabits a habitat that has only sporadically been investigated worldwide.
