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



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