green crab

Shore-dwelling invasive crustacean

A green crab is a small shore crab native to European and North African coasts that has become an invasive species in North America, Australia, and other regions.

Despite the name, its shell color ranges from green to brown, orange, or reddish, though the underside typically shows green.

Green crabs are aggressive predators of shellfish and have significantly impacted commercial clam and mussel beds in waters where they've established themselves.
