Invasive Marine Life Found in Puget Sound

Emergency action was taken to eradicate an invasive marine species that was discovered recently in Puget Sound waters off Edmonds, Washington. The species, colonial tunicate, could potentially pose a threat to Washington State's diverse marine life. Divers found a 30-square-foot growth of the siphon-feeding animals, which form dense mats made up of thousands of organisms and can suffocate clams, mussels and other native species. Divers secured a plastic tarp over the colonial tunicate mass, and placed chlorine tablets under the tarp in an effort to kill the colonial tunicate. For more information, visit http://wdfw.wa.gov/.
