Caulerpa taxifolia (invasive genotype)
Taxonomic Group: Algae
Common name: 'KILLER ALGAE'

Overview:

Caulerpa taxifolia is a green seaweed, which grows as long lines of fern-like fronds arising from a linear or branched stolon. The invasive strain of this species is native to Moreton Bay in Queensland, Australia and has been introduced to the Mediterranean, southern Australia, and California. Its invasion in the Mediterranean made headlines, as it spread quickly and extensively covered the seabed in many places. However, its abundance peaked in 2007 and has declined since. It has been widely used as an ornamental plant in public and private aquaria which is considered the main vector for its introduction. Populations in California were successfully eradicated in 2002 and its sale was banned throughout the state. Introduced populations have had negative impacts on the distribution and abundance of seagrass beds, macroalgae, and invertebrate communities.
