The European green crab ranks among the world’s worst invasive species — decimating populations of native clams, fish and other crabs. The voracious predators arrived in the U.S. from Europe in the 1800s, and today cost the East Coast fishing industry $19 million each year.

More recently, green crabs are threatening commercial fisheries in California.
