Zebra Mussels FAQs - 15 Found
Mussels are also called "bivalves." This means they have two shells or valves (a right valve and a left valve). The zebra mussel gets its name because of the dark, striped pattern on each valve. Usually the shell is a light color (tan, beige) with zig-zag stripes. However, some are almost completely all brown and the stripes are not pronounced. Even more rare are those nearly all light colored with little striping.
