The Water Deer (Hydropotes inermis) is a usually solitary animal, besides the rutting months, and a good swimmer. There exist two subspecies: the Chinese Water Deer (Hydropotes inermis inermis) and the Korean Water Deer (Hydropotes inermis argyropus). Wild populations of escaped water deer live in the United Kingdom and in France. The water deer is considered a primitive member of the Cervidae family (Deer), because buck has large canine teeth and has no antlers, both evolved by other deer.
