The Chinese mitten crab is a species of freshwater crab native to the coastal regions of China and Korea. It is known for its distinctive furry claws, which resemble mittens, giving it its name. These crabs typically inhabit rivers, lakes, and estuaries, and they are often found in brackish water. In recent years, the Chinese mitten crab has become an invasive species in various parts of the world, including Europe and North America. Their ability to adapt to different environments allows them to thrive, often disrupting local ecosystems and competing with native species for resources.
