A red seaweed in the Tasman Sea has no bacteria colonizing its surface. Seaweeds live in the ocean which is a "soup of bacteria". This seaweed deafens the bacteria making it impossible for them to realize where their buddies are or coordinate joint actions. The additional advantage is that they will not mutate and become resistant.
