description Asian Paddle Crab Overview
The Asian paddle crab (Charybdis japonica) is a swimming crab native to coastal waters of East Asia and other parts of the western Pacific. Like other members of the family Portunidae, it has a flattened final pair of legs that function as paddles, allowing it to swim efficiently. It inhabits marine and estuarine environments, is harvested as seafood, and has established populations outside its native range, where it may be treated as an invasive species.
