well hi there its not commensalism its parasitism because when the barnacles attach themselves to the whale they benefit as they get transportation but the whales get this itchy feeling (skin ulcers) due to barnacles stuck to its skin so it gets harmed the "guest" which are the barnacles is harmaful to the " host" which is the whale .

A barnacle is a crustacean so it has a shell.
Patches of skin on a whales head made up of lice and barnacles.
They aren't symbiotic : the barnacles (crustaceans related to crabs) are parasites on the whale's skin, and will also attach to boats, docks, and other marine locations.
An example of commensalism is the relationship between barnacles and whales. Barnacles attach themselves to the skin of whales and benefit by getting a free ride through the water and access to nutrients. The whales are not significantly affected by the presence of the barnacles.
An example of commensalism is the relationship between barnacles and whales. Barnacles attach themselves to the skin of whales to gain protection and access to nutrients in the water, while the whales are not significantly affected by the presence of the barnacles.
An example of commensalism is the relationship between barnacles and whales. Barnacles attach themselves to the skin of whales and benefit from the whale's movement and access to food particles, without causing any harm to the whale.
Barnacles form a symbiotic relationship with whales by attaching themselves to the whale's skin or baleen plates. The barnacles benefit from the whale's movement, which provides them with a constant flow of food-rich water. In return, the barnacles can cause some drag on the whales, affecting their swimming efficiency and potentially increasing energy expenditure.
Barnacles stick to the boat hull and grow creating a sort of skin over the hull. This in turn slows boat by taking away smoothness of hull and adding weight. Barnacles get knocked off and fall off , which pulls outer hull coating off allowing rot to get in.
That doesn't make any sense... I can't imagine how the jewelry can get stuck to your skin
