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 .
The barnacle gets free food and a free ride and the whale is not harmed by the barnacle but does not benefit ether from the relationship. therefore the relationship between the Grey Whale and the barnacle is a perfect example of commensalism.

commensalism == the barnacle living on the whales back gains safety and protection where as the whales does not either gain or lose anything from the relationship
Mutualism
The deer eat the grass. The grass gets no benefit from the deer. This is called commensalism.
the symbiotic relationship between a squirrel and nut tree is the squirrel gets a home and food and the tree doesn't get any thing so it is commensalism.
The wolf is in a commensalism relationship in the way that it gets its food when it comes from another animal. The wolf is not harmed, but the animal that it uses for food is.
Commensalism is where one species benefits and the other is unaffected. Like a bee and a flower. The bee benefits because it gets the nectar from the flower. The flower is unaffected because nothing happens to it.
It is possible that too many barnacles could cause drag on the whale or invite infection if they penetrate too deep into the whaleâ??s flesh. In male humpbacks, who fight over females by ramming and slapping at each other, a sharp barnacle coating may be helpful.
Cowbirds eat the parasites that may infest the bison. This assists them both. The cowbird gets a meal and the bison gets cleaned. This is a form of mutualism, a symbiotic relationship in which both organisms are helped, rather than commensalism where only one of the pair benefits.
the carabao gets its flea control solution with the help of the carabao egret while the carabao's built serves as a defense or source of security..
Bangaii Cardinal and the sea urchin. Cardinalfish gets protection, and the urchin doesn't benefit or get hurt
