Thanks for the heads up. I just got done watching it. The subject of this episode is exactly the reason I belive so strongly in conservation and responsible aquarium habits. While the release into the wild might have been a whole hearted accident we can now see what can happen when non indigenous species are introduced.

That was a great special. I caught it a couple months ago.

It basically is a very hardy and fast growing strain of caulerpa that smothers everything in it's path. It is thought to have been introduced inadvertently by aquarium hobbiest to areas it is not native to so there are no natural predators to control it.
Thanks for the heads up lasek2k1.

The strain is a giant version of the wild type of calerpia taxifolia (sp?). In addition the algae has a high consentration of a specific type of toxin that makes it uneadible by nearly every form of natural wildlife found in the areas its growing. Even the reef's lawn mowers the sea urchin does not find the algae palteable. What this means is it grows out of control and chokes everything in its path out. Growth rates where predicted to be an 1" or more per day and since it has no female gametes it means that the plant and clone itself with even the smallest bit of the inital plant so removing it is almost impossible since you have to remove every single bit or it will just grow back.
