Do barnacles affect whales?

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.

Are barnacles uncomfortable for whales?

The barnacles are just along for the ride. They don’t harm the whales or feed on the whales, like true parasites do. Barnacles find the slow-swimming gray whale a good ride through nutrient-rich ocean waters.

Do barnacles slow whales?

Most scientists agree that barnacles do not harm whales because the drag produced from the barnacle is not enough to affect the whales and the whale is not hurt by the cement of the barnacles.

What is the relationship between barnacles and whales?

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.

Do barnacles hurt humpbacks?

The barnacles that have fixed themselves to the skin of the humpbacks are very sharp. This means when humpbacks are within close contact to each other they will likely cut themselves on the barnacles. This is why males often have more scarring of this kind than females.

Do barnacles hurt animals?

Barnacles often live on whales, crabs, rocks, boats and sea turtles. While a few species of barnacle are parasitic, most barnacle species are harmless to other animals. They filter feed food particles out of the water and do not harm the animal they live on.

How do whales scrape off barnacles?

As the whale travels through the ocean, the barnacles extend their filtering baskets and sea water passes through trapping microorganisms for them to eat. Sometimes gray whales scrape off the barnacles by rubbing on underwater rocks. This leaves a white scar which gives these whales a mottled gray color. Now you know!

Do barnacles attach to humpback whales?

Barnacles regularly colonize the skin of filter-feeding whales, and they often do so in huge numbers — one humpback whale, for instance, can host almost 1,000 pounds of barnacles.

What would most likely happen to the whale population of the barnacle population decreased?

The whale population would stay the same. What would MOST LIKELY happen to the whale population if the barnacle population decreased? The pine population would increase.

Do orcas get barnacles?

TL;DR: Orcas do get lice, barnacles and other nasties. They do however seem to host relatively fewer than their larger krill-nomming contemporaries. Might be because killer whales don’t enjoy barnacle food, but do like a cheeky rub and cool waters.

Does a barnacle harm the whale it live on?

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.

What does a barnacle do to a whale?

Whales and barnacles, at the least, engage in a commensal relationship. This type of relationship provides a benefit to one party, such as the barnacle that is able to settle and filter food on a movable island, while providing no effect to the second party, in this case the whale.

How does a barnacle help a whale?

Since whales are filter feeders, barnacles attach themselves to their skin, and all they need to do is extend their filtering arm to catch some of the whale’s tiny prey. In exchange, barnacles can also help whales especially when they cover most of their bodies.

Why do the barnacles attach to the whale?

The barnacles attach themselves to the whales as the whales make their way across the sea for nutrients and new habitats. These hermaphrodites consist of six free-swimming plankton naupliar stages (4). Even though the barnacle eggs can self fertilize, it is more likely for another barnacle to fertilize it.
