A cheeky visitor sneaks into the Tyne, but will the local wildlife be smitten by its mittens?
Known in China as the big sluice crab or the Shanghai hairy crab, this burrowing crustacean can survive in coastal waters as well as fresh. It's additional high tolerance to pollution makes it peculiarly well adapted to migration beyond its historic environment. The crab is considered an invasive species of concern in both the United States and Europe, where its import is banned. However, in its native China the mitten crab is served as an autumn delicacy, and is in relatively high demand. In 2010 the first mitten crab vending machine was opened; a refrigeration unit kept the crabs at a temperature which would induce sleep or lethargy while they waited to be purchased.
