Origin and Distribution

Caulerpa is originally from tropical coastal waters around the world, but became invasive because it was bred to tolerate the rough conditions and cool waters in aquaria.

Transportation

Caulerpa is introduced in to a new environment primarily by:
  A. The gut of a fish that eat Caleurpa.
  B. Sea kayakers who harvest the sea weed for food.
  C. People dumping their aquariums into the gutter, storm drain, creek, lagoon, bay, harbor, or the ocean.
  D. Being snagged by an anchor.
  E. C and D above.
  F. B and C above.

Environmental Impact

Caulerpa is called "killer algae" because:
  A. It is able to grow in many temperatures and on many surfaces, including sand, gravel, and rocks.
  B. It contains poisons that are toxic to fish and can kill neighbouring sea plants.
  C. The dense mats of Caulerpa change the habitat so fish, invertebrates, and plants can't live there.
  D. All of the above.

Economic Impact

To date, it has cost 4.5 million to control invasions in Agua Hedionda and Huntington Harbor, California. We can prevent this from happening again by:
  A. Telling others about the problems Caulerpa causes.
  B. Disposing of aquarium contents by putting it in a plastic bag, freezing for 24 hours, and them throwing it in the        trash.
  C. Never dumping your aquarium in the gutter, storm drain, creek, lagoon, bay, harbor, or the ocean.
  D. All of the above.

Control

We should not be concerned if we find Caulerpa in California, Oregon, or Washington coastal waters because eventually the tide will go down and the Caulerpa will die due to exposure to the air.
