Mitten crabs spend most of their life in fresh water, but they must return to the sea to breed. During their fourth or fifth year in late summer, the crustaceans migrate downstream, and attain sexual maturity in the tidal estuaries. After mating, the females continue seaward, overwintering in the deeper waters. They return to brackish water in the spring to hatch their eggs. After development as larvae, the juvenile crabs gradually move upstream into fresh water, thus completing the life cycle.

This species' distinguishing features are the dense patches of dark hair on its claws. The crab's body is the size of a human palm.

Hairy crab as famous Shanghai cuisine.

In contrast, the crab is a famous delicacy in Shanghai cuisine and is prized for the supposed aphrodisiac qualities of the female crab's ovaries. Concerns have been raised that the population and origin of the crab may be affected because of over fishing of the species in the Yangtze River. Today Yangcheng Lake is the most famous area for the Chinese mitten crabs. The crab meat is believed by the Chinese to have a "cooling" (yin) effect on the body. Chinese spend hundreds of yuan just to taste a small crab from that lake. Most of these are exported to Shanghai and Hong Kong, and high-profit foreign markets. Responding to the spread of the crab to the West, businessmen have started seeing it as the new source of crab for supporting the huge appetite in China market.
