Is this the green crab we know?
Europe's green crab has invaded the U.S. and is now decimating native species in large areas of the U.S. East and West coasts. Introduced on the East Coast in the 1800s, the voracious green crab has eaten its way and spread along virtually the entire Eastern coast. First found on the West Coast in San Francisco Bay in 1989, most likely through ship ballast water, the crab spread northward over 1000 miles in less than a decade. Now the crab has been found in Morro Bay, the first time it has been seen south of Morro Bay. The green crab has an incredible appetite, eating up to 40 other crabs and crustaceans a day. Unfortunately, it itself is too thin and not meaty enough to be considered a viable source of food for people.
