The zebra mussel is an invasive species that poses a significant threat to ecosystems along the Pacific Coast.

Zebra mussels (Dreissena polymorpha), originally from the Great Lakes, have rapidly spread throughout North America, endangering local ecosystems. These small freshwater mussels outcompete native species for food and habitat, attaching themselves to various surfaces such as boats and water infrastructure, which can lead to costly damage and blockages. Their ability to reproduce prolifically disrupts local ecosystems by filtering excessive nutrients from the water, altering the food web, and adversely affecting native aquatic species. To combat this issue, effective management strategies are essential, including monitoring water bodies, raising public awareness about the dangers of invasive species, and enforcing cleaning protocols for boats and equipment to prevent further spread. Safeguarding the Pacific Coast's aquatic ecosystems from zebra mussels is crucial for preserving biodiversity.
