Zebra mussels, originating from Eurasia's fresh waters, have distinctive striped patterns on their shells. Despite their small size, they're known for their significant impact on the habitats they colonize.

Primarily filter feeders, their razor-sharp shells often necessitate protective footwear in the waters they inhabit. Since their invasion of the Great Lakes, these mussels have become a prominent issue, fastening to various submerged surfaces, including boats, docks, and even other mussels. 

Hydroelectric companies and municipal water suppliers grappling with blockages from dense populations have found some relief using cupronickel alloy coatings, which zebra mussels struggle to attach.

While they've contributed to the near-extinction of several Great Lakes species, these mussels are effective indicators of environmental pollution, specifically to contaminants representative of water pollution.
