Diogenes heteropsammicola is a species of hermit crab that lives within "walking corals" of the genera Heterocyathus and Heteropsammia. Igawa, Momoko, and Makoto Kato. “A New Species of Hermit Crab, Diogenes Heteropsammicola (Crustacea, Decapoda, Anomura, Diogenidae), Replaces a Mutualistic Sipunculan in a Walking Coral Symbiosis.” PLOS ONE, Public Library of Science, journals.plos.org/plosone/article?id=10.1371%2Fjournal.pone.0184311.



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.
