Diogenes heteropsammicola is a species of hermit crab that lives within "walking corals" of the genera Heterocyathus and Heteropsammia. The Diogenes heteropsammicola and the genera Heterocyathus and Heteropsammia are symbiotic with eachother. Diogenes heteropsammicola only associating with the genera Heterocyathus and Heteropsammia suggests that the species hermit crab is required to associate with the corals.



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, it is often found inside the corals instead.
