How do barnacles affect whales?
However, a few exceptions to the rules of commensalism can occur. On some whales, too many barnacles can cause drag. Minor skin irritations or infections may arise. On the plus side, the barnacles can actually protect the whales, like a suit of armor.
How do barnacles breathe?
Although the barnacle lacks gills, it can breathe just fine. Gas exchange is accomplished by diffusion through the thin exoskeleton of the carapace, located in the mantle cavity.
