Aquatic Invasive Species
Caulerpa taxifolia, a green seaweed, has invaded southern California, south-eastern Australia, and the Mediterranean Sea. In 2004, the alga covered over 200 kilometers of coastline in the Mediterranean. Dubbed the "killer alga" because of its major ecosystem and economic impacts to tourism and Fisheries, Mediterranean populations rapidly became too widespread to eradicate. In California and southern Australia, millions of dollars are being spent to eradicate this weed and monitor for new outbreaks.
