Pleasant Harbor on Hood Canal, near Brinnon, WA is unfortunately home to thousands of invasive tunicates - Styela clava has taken over the underside of docks, and is fouling propellers and hulls of the boats in the marina. NOTE: The docks have all been replaced in February 2009. We'll see how long it takes for the Styela clava to grow back onto the docks.
