Note to players: Either the name of the class or the common name of any of its major species is acceptable. Ecologists are deploying a “ribbed” species in this class that absorbs heavy metals to clean up Atlantic salt marshes. Species in this class use dopamine in the foot protein of their byssal threads. Mytilus californianus, a member of this class, is preyed upon by starfish in tidepools in the first described keystone interaction. Ships in Lake Erie are quickly covered by a layer of an invasive species in this class named for its (*) zebra stripes. Humans mainly get Vibrio vulnificus infections by eating animals in this class. Animals in this class have nacreous shells and form layers of calcium carbonate around food particles to produce iridescent gems. For 10 points, name this class of mollusks that have a hinged shell and can produce pearls. ■END■
