Barnacles
Barnacles are a type of marine crustaceans that attach themselves to hard surfaces, such as the hulls of ships, piers, and rocks. They are filter feeders, using their feather-like appendages to capture plankton and other small organisms from the water. Barnacles can cause significant damage to ships by increasing drag and reducing speed, which can lead to increased fuel consumption and higher operating costs. They can also create a rough surface on the hull, which can reduce the effectiveness of anti-fouling coatings. Barnacles are commonly removed from ships through a process called hull cleaning, which involves scraping or pressure washing the hull to remove the attached organisms.
