Green mussels

These pests are not known to be established in the wild in Australia, but could be found on beaches if they were introduced. Shells of both the Asian and New Zealand species are bright green to greenish brown outside and pearly-white inside with a bright green lip. These mussels have the potential to outcompete native species, clog water pipes and other man-made structures. Any green mussels found on the beach could be pests!
