where is the european green crab native to
Carcinus maenas C. maenas is a widespread invasive species, listed among the 100 "world's worst alien invasive species".[2] It is native to the north-east Atlantic Ocean and Baltic Sea, but has colonised similar habitats in Australia, South Africa, South America and both Atlantic and Pacific coasts of North America. It grows to a carapace width of 90 millimetres (3.5 in), and feeds on a variety of molluscs, worms and small crustaceans, potentially impacting a number of fisheries. Its successful dispersion has occurred via a variety of mechanisms, such as on ships' hulls, sea planes, packing materials, and bivalves moved for aquaculture.
