Definition
A zebra mussel is a small, invasive freshwater mussel known for its distinctive striped shell. Originating from Eastern Europe, it has spread to many parts of the world, causing ecological and economic damage. Zebra mussels attach to hard surfaces, forming dense colonies and clogging pipes. Think of them as the tiny squatters of the aquatic world. They filter feed at a high rate, outcompeting native species for resources. They pose a significant threat to biodiversity.
