The Chinese mitten crab (Eriocheir sinensis; simplified Chinese: 大闸蟹; traditional Chinese: 大閘蟹; pinyin: d\xe0zh\xe1xi\xe8, lit. "big sluice crab"), also known as the Shanghai hairy crab (上海毛蟹, p Sh\xe0nghǎi m\xe1oxi\xe8), is a medium-sized burrowing crab that is named for its furry claws, which resemble mittens. It is native to rivers, estuaries and other coastal habitats of East Asia from Korea in the north to Fujian, China in the south. It has also been introduced to Europe and North America, where it is considered an invasive species.[1][2]
