Zebra Mussel, Dreissena polymorpha
Jean-Marc Gagnon, Chief Collection Manager for invertebrates, thinks zebra mussels are both amazing and terrifying. This exotic species has cost millions of dollars in damages since it was first noticed in North America in 1988. André Martel, Research Scientist, studies zebra mussels two ways -- he dives to study them under water, and he uses collected specimens to study them in the lab. |
