How Do Barnacles Attach to Whales? | Scienceline

Commensalism is a relationship between two organisms in which one organism benefits and the These barnacles attach themselves to the bodies of whales.

Both organisms benefit in the relationship, the bee derives nectar and pollen from the plant while the plant becomes cross fertilised by the bees. On the right is a picture of an Australian native bee, known as the blue banded bee Amegilla cingulata Click to see a detailed image.
The relationship between the barnacles and the whale is an example of commensalism, where the barnacles benefit by being transported to food rich regions of the ocean while the whale is not harmed in any way in this relationship.
Epiphytes are plants that grow on other plants in a non-parasitic relationship. Although an epiphyte derives its moisture and nutrients independently of its host it benefits by been high above the ground out of reach of herbivores and where there is more sunlight.Examples of Commensalism
The host plant does not benefit nor is it harmed. This relationship also is an example of commensalism. Another type of relationship is known as a predator-prey relationship. Simply put, a predator is an organism that eats another organism.

The organism being eaten is the prey while the organism eating the other is the predator. For example, a dragonfly will eat flies and therefore the dragonfly is the predator while the fly is the prey. This predator-prey relationship does not only apply to animals it can also apply to plants such as when a grasshopper eats grass, the grasshopper is the predator while the prey is the grass.
Predator-prey relationships evolve over time, where the predator evolves all that is needed to successfully its prey. This may include camouflage, speed or bigger jaws.

While in the ant's nest the seeds are safe from bushfires.
This relationship evolved over thousands of years and is an example of 2 A tapeworm lives in the intestinal tract of humans. It was fashionable in the s for people to ingest tapeworms so that they can loose weight.
To better illustrate this relationship, Trull outlined the three types of symbiosis: If you think of mutualism as mutually beneficial, and parasitism as one benefitting at the cost of the well-being of the other, commensalism falls right in between. Commensalism is a type of symbiotic relationship where one species will benefit while not affecting the other species in a positive or negative way.
Symbiotic Sea Life
The relationship between Humpback Whales and marine birds is an excellent example of commensalism. Humpback Whales will consume up to 1 ton of sand eels every day.
When a large school of these fish is located near the surface of the water, the whales will then rise up with their mouths agape and take in mouthfuls of them. This method is particularly effective for the whales to consume the food they need to survive, but it also benefits other species as well. Farther out at sea however, other birds will also get in on the feeding frenzy.

The term marine bird refers to birds that we really do not see on the Cape, because they typically nest on islands very distant to us,and when they are in the waters surrounding Cape Cod, they have no reason to come to land.
These birds are so perfectly adapted to the conditions of the oceans, including the ability to get all the food they need, that they spend all their time at sea. Common examples of these pelagic birds include: The great shearwaters nest far south on islands off the southern coasts of South America and Africa, and spend summers in the waters around the Cape.
