This project aims to stop a new invasive species before it becomes a large-scale problem. To prevent the exotic snail Littorina littorea from establishing itself in San Francisco Bay, the Estuary Partnership will search for and remove the snails from areas with known, incipient populations. Littorina specimens will be preserved and made available for future genetic studies that could help to determine the best control strategies to prevent them from reinvading. New outreach materials will help inform the public and encourage reporting of any future sightings.

They're also featured in Asian cuisines, and can be purchased live in some local Asian markets. And some of them are getting into San Francisco Bay.
Marine biologist Andrew Cohen says there's lively scientific debate over whether L. littorea is native to North America as well as Europe. Some have concluded it was intr... READ MORE |
