How do you remove barnacles?

What is the purpose of barnacles?
Because they are
filtering organisms
, they play an important role in the food chain. Barnacles are suspension feeders, consuming plankton and dissolved detritus suspended in seawater and are therefore essential in cleansing that water for other organisms.
What animal eats barnacles?

Do barnacles feel pain?
Pain is in the Brain. Crustaceans have long been viewed as maintaining reflexes that do not cause internal suffering, which would mean

Do barnacles feel pain?
