The crustacean known as the orangutan crab [achaeus japonicus] (orangutan crab), which is often found to be symbiotic with vir philippinensis (bubble coral shrimp), should be classified as a special genus of trichotan crabs.
Unlike the menacing red crab, which comes from Indonesia with its namesake, this furry-looking creature is widespread in Asian coral reefs.
It is perfectly symbiotic with vir philippinensis (bubble coral shrimp) and the genus Euphyllum coral, a variety of corals in the genus Vesicle coral, which collects plankton through long hairs on the body, and is likely to eat some food caught by corals.
They are easily detached from corals during the collection and transport of corals, and coral collectors always remove them from symbiotic corals because they look like creatures that threaten corals. Moreover, for extra income, coral gatherers always transport them separately and sell them separately, so we can easily raise them in aquariums and observe them, which is a very ornamental and fascinating creature.
