      Summary Author:  Mila Zinkova   
      
       Biofouling is an accumulation of marine organisms found on the   
      underwater parts of vessels, docks, etc. (top photo shows biofouling on   
      a shipwrecked hull). On occasion, they can be dangerous to the   
      environment. For example, on January 1, 2023, a  cruise ship was   
      refused permission to dock in Australian ports because it carried a   
      deleterious fungus on its hull.   
      
      At about the same time, a small shipwreck was washed out at  Ocean   
      Beach in San Francisco. It was almost completely covered by biofouling,   
      which included a sea anemone, sponges, algae and barnacles. The   
       barnacles were still alive since they're able to survive for many   
      years without water, as you can see from  this video (made of the   
      shipwreck). If you look closely, you can them popping out of their   
      shells (bottom photo, at top center).
