FRESHWATER CRAB  SPECIES

There are 6 species of freshwater crabs in Hong Kong, 4 of which are considered to be endemic to Hong Kong. However, it is likely that their populations just haven't been studied in Guangdong, or outside populations have become extirpated and Hong Kong is the last remaining stronghold (statistics acquired from AFCD, HKwildlife and AECHK).
