Eriocheir sinensis reaches 5-10 cm of carapace. Its carapace is square, dark brown-green. Its claws (chelipeds) are particularly large and covered with dense bristles giving them a 'mitten' appearance. It is a migratory crab: it lives in fresh or brackish water then descends to the sea to breed. Considered invasive in many regions.
