Invasive Snail Found in Minn. Harbor
DULUTH, Minn. (AP) -- A small, spiral-shaped snail that clones itself and is native to New Zealand has been discovered in Duluth-Superior Harbor and the St. Louis River estuary, raising concerns about the impact of another invasive species.
The snail, called the New Zealand mudsnail, is only about as large as a peppercorn when fully grown. But one snail and its offspring can generate hundreds of thousands of clones each year.
