Zebra mussels and why we should care

Zebra mussels are an invasive mollusk. Their name comes from the zig-zagged stripes on their shells.
According to the USGS, zebra mussels negatively impact ecosystems in many ways. They filter out algae that native species need for food and they incapacitate native mussels. Power plants must also spend millions of dollars removing zebra mussels from clogged water intakes.
