Notable details
- Native to the Ponto-Caspian region of Eastern Europe, quagga mussels were first detected in Lake Erie in 1989.
- A single adult filters up to 1 liter of water per day, removing phytoplankton that native species depend on.
- Unlike zebra mussels, quagga mussels can colonize soft lake-bottom sediment and survive depths exceeding 100 meters.
- Named for the extinct quagga — a zebra relative — because of the mussel's faint striped shell pattern.
- It spreads mainly by boat; a single drop of bilge water can carry microscopic veliger larvae.
