Juvenile zebra mussels are about the size of peppercorns. The ones pictured here are estimated at a year old and are about the size of a person’s pinky fingernail. Adult zebra mussels can be two inches long, or about the size of a half dollar, but most are less than an inch long. On smooth surfaces, young zebra mussels tend to feel like fine sandpaper. Zebra mussels can be identified by their alternating dark and light colored stripes, their black to brownish D-shaped shell and the byssal threads they use for attaching to objects.
