Take away the sea stars along the northwest coast of the United States, for instance, and the ecosystem changes dramatically; in the absence of these sea stars, their favorite prey, mussels, takes over and makes it hard for other species that used to live there. Sea stars are known as keystone species, because as top predators they determine ecosystem structure by their eating habits.
