The hybrid form of Caulerpa taxifolia was most likely produced as a result of the tropical form having been captively bred for a number of years by the Saltwater Aquarium at the Wilhelmina Zoo in Stuttgart Germany. They were trying to identify a hearty breed of seaweed that could be used commercially in saltwater aquariums that was also very attractive to the eye with a form and color that would make a beautiful backdrop for exotic fish. After having been exposed to tank chemicals and ultraviolet lights over the course of several years, it is believed that, unbeknownst to the staff at the time, these abiotic stressors created the current mutant form of Caulerpataxifolia. Samples were sent to various institutions, including the Oceanographic Museum in Monaco, where it was probably leaked into the environment. A marine biologist, Alexandre Meinsz, first discovered it under the windows of that Museum when it was first found in the sea as a small patch of about a square meter. It spread to cover more than 2.5 acres in less than five years and by 1997 it covered more than 11,000 acres along the coast of the Mediterranean, reaching North Africa.

1. Research this species, Caulerpa taxifolia , and describe its physical appearance. Relate its physical properties to what you perceive to be the reason it can be so invasive.
2. What are some of the reactions/actions being taken to eradicate existing invasion and prevent further invasion by this species?
3. Research an invasive species and write two to three paragraphs about it in your own words.
