Genus
Common name: Orchid Crab
Scientific name: Lissocarcinus
Lissocarcinus is a genus of crabs known as Orchid Crabs, named for their delicate, flower-like appearance. These crabs are commensal with sea cucumbers, often found living on or near their hosts. They are small, with a carapace width typically not exceeding a few centimeters, and exhibit a range of colors, often matching their sea cucumber hosts. In the aquarium, they are valued for their unique behavior and the symbiotic relationship they maintain. They are generally peaceful and can be a fascinating addition to a reef tank with ample hiding places and a compatible host.
