Diogenes heteropsammicola is a species of hermit crab that lives within "walking corals" of the genera Heterocyathus and Heteropsammia.



These coral have an internal cavity that is typically occupied by a symbiotic sipunculan worm. In the crab's habitat in the Ōshima Straight south of Amami Ōshima, the sipunculan worm is often found inside the corals instead.
