Mussels Evolve Rapidly to Thwart Crab InvadersBy Kerry Grens on Thursday, August 10, 2006.One of the most dominant crab species on the New England coast is actually an invader. The Asian shore crab has been spreading swiftly along the Atlantic since it arrived in the 1980s. And it has found a smorgasbord of goodies to munch on—including the native blue mussel.
