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, it is often found inside the corals instead. (citation practice from Deforestation in Madagascar)

Population increase[edit]
Since the 1940s, the population in Madagascar has rapidly increased, putting pressure on the land available for housing and farming. Thousands of hectares of rainforest have been cut down in order to provide for the increased population.
