Helice tridens is a species of crab which lives on mudflats around the coasts of Japan and the Korean Peninsula.[1]

Ecology

It is semi-terrestrial, returning to the sea to spawn.[2] The species appears to be adversely affected by the presence of raccoons (Procyon lotor), an invasive predator.[2] H. tridens has a salinity requirement which lies between those of two other estuarine crabs in Japan, Helicana japonica and Chiromantes dehaani.[3]

Smaller individuals shelter in burrows in reed marshes, apparently in order to avoid cannibalism; this may also be the reason for the migration of larger individuals to brackish water lagoons in summer, when the crabs exceed their carrying capacity.[4]

Taxonomy

Helice tridens was first described by Wilhem de Haan in an 1835 volume of Fauna Japonica, as Ocypode tridens.[5] The former subspecies H. t. wuana and H. t. sheni are now recognised as a separate species, Helicana wuana.[6]
