Spurwinkia salsa is commonly known as the Spurwink Hydrobe. It is a small estuarine snail which is native to eastern North America from New Brunswick to northern Florida. Introduced populations are known from San Francisco Bay, California, where it was first discovered in 2008. However, due to its small size, it may have been introduced years prior and been undetected. It inhabits marshes, mudflats, and submerged vegetation from the upper intertidal to shallow subtidal. No impacts have been reported from San Francisco Bay.
