the non-native Caulerpa multiplied rapidly

Further selective breeding made it even heartier,and soon it was used in aquariums around the world.But it was not long before a sample of this aquarium-developed super algae turned up in the Mediterranean Sea near the famed Oceanographic Museum of Monaco.The marine biologist who found it believed that the museum had accidentally realeased it into the ocean along with aquarium waters,while museum directors claimed it had be carried into the area by ocean currents. Regardless of how it ended up there, the non-native Caulerpa multiplied rapidly, having no natural predators due to releasing a toxin that keeps fish away.
