Hardy and decorative, Caulerpa seemed a blessing at first, and it soon
became the most popular aquarium plant on Earth. The Monaco Oceanographic
Museum obtained a sample, and it was in the harbor just beneath this
institution-where famed oceanographer Jacques Cousteau was the director at
the time-that Caulerpa was first spotted getting a toehold in nature. The
killer algae have been spreading ever since.

I would not call it killer really, but indirectly it can kill other
critters and plants. Hydrilla could also be called this if someone
tried to swim through a thicket, or from West Nile virus habitat
vectors(mosquitos etc).
443 milion pounds of seafood was taken in and around CA 2001,
prevention is the best method they have at control.
