How is barnacles on a whale commensalism?
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.
What type of relationship exists between barnacles and whales?
Commensalism As we continue in our imaginary deep-sea voyage, we may observe the commensalistic relationship that exists between barnacles and humpback whales. Commensalism happens when one species lives with, on, or in another species, known as the host. The host species neither benefits nor is harmed from the relationship.
What do barnacles do to whales?
They don't harm the whales or feed on the whales, like true parasites do. Barnacles don't serve any obvious advantage to the whales, but they give helpful lice a place to hang onto the whale without getting washed away by water. Barnacles find the slow-swimming gray whale a good ride through nutrient-rich ocean waters.
Which type of symbiotic relationship do barnacles that are attached to a large migrating whale represent?
Whale barnacles typically attach to baleen whales and have a commensal relationship–the barnacle benefits and the whale is neither helped nor harmed.
Do barnacles harm whales?
They don't harm the whales or feed on the whales, like true parasites do. Barnacles don't serve any obvious advantage to the whales, but they give helpful lice a place to hang onto the whale without getting washed away by water.

Barnacles find the slow-swimming gray whale a good ride through nutrient-rich ocean waters.
Why do barnacles attach to whales?
Barnacles find the bellies and backs of whales an ideal breeding ground. By hitching a free ride on whales, barnacles get a relatively safe place to live, enough water passing by them to engage in filter-feeding as a whale swims, and a proper ground to expand their colonies.
Do barnacles protect whales?
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 whales get rid of barnacles?
Whale lice are orange colored patches around the barnacles and in crevices of the whale's body such as creases and the mouth line. To get rid of the whale lice, whales rub themselves along the sea bottom or breach. Gray whales feed on bottom sediments and scrape off barnacles and whale lice as they feed.
Why do barnacles stick to whales?
Barnacles find the bellies and backs of whales an ideal breeding ground. By hitching a free ride on whales, barnacles get a relatively safe place to live, enough water passing by them to engage in filter-feeding as a whale swims, and a proper ground to expand their colonies.
Why do whales need barnacles?
Barnacles don't serve any obvious advantage to the whales, but they give helpful lice a place to hang onto the whale without getting washed away by water. Barnacles find the slow-swimming gray whale a good ride through nutrient-rich ocean waters. As larvae, the whale barnacles swim freely in the ocean.
