Detailed explanation-1: -In the case of barnacles and whales, only the barnacles benefit from attaching to the whales, but at no biological cost to the whale. This type of symbiotic relationship is known as commensalism. In this case, attaching to the whales gives the barnacles a stable place to live, a free ride, and access to plenty of food.

Detailed explanation-2: -MORE ON THIS: The relationship between these barnacles and humpback whales is an example of commensalism, where one species benefits and the other is unaffected. The barnacle benefits from this relationship because it is provided with a place to live and filter food.

Detailed explanation-3: -Barnacles (balanus glandula) are sticky little crustaceans related to crabs, lobsters, and shrimps. Those aren’t dragon claws-they’re gooseneck barnacles! These filter feeders are found in the rocky tide pools of Olympic Coast National Marine Sanctuary.

Detailed explanation-4: -Commensalism occurs when one species benefits from the interaction while the other is unaffected. Barnacles and whales are a good example of commensalism. Barnacles hitch a ride on whales which allows them to capture and eat more plankton while the whale is unaffected by the barnacles’ presence.

Detailed explanation-5: -As we continue in our imaginary deep-sea voyage, we may observe the commensalistic relationship that exists between barnacles and humpback whales (Megaptera novaeangliae). Commensalism happens when one species lives with, on, or in another species, known as the host.
