Commensalism is a long-term biological interaction in which members of one species gain benefits while those of the other species neither benefit nor are harmed. [1] This is in contrast with mutualism , in which both organisms benefit from each other; amensalism , where one is harmed while the other is unaffected; and parasitism , where one is ...
The bluestreak cleaner wrasse is found on coral reefs in the tropics from the Red Sea and Indian Ocean to the western Pacific (including Papua New Guinea, Japan, Fiji, and French Polynesia). [5] It was first recorded from the Kermadec Islands Marine Reserve north of New Zealand in 2015, after researchers examined hundreds of hours of unused ...
Commensalism benefits one organism and the other organism is neither benefited nor harmed. It occurs when one organism takes benefits by interacting with another organism by which the host organism is not affected. A good example is a remora living with a manatee. Remoras feed on the manatee's faeces.
The crab-coral interaction described above is also an example of refuge from competition, since the herbivory of crabs on seaweed reduces competition between coral and seaweed. [12] Similarly, herbivory by sea urchins ( Strongylocentrotus droebachiensis ) on kelps ( Laminaria spp.) can protect mussels ( Modiolus modiolus ) from overgrowth by ...
Planktivorous fish (8, some damselfishes and triggerfishes) transfer energy from zooplankton up to reef predators like jacks (9), [101] which provide top-down control of reefs [102] and are important targets for shoreline recreational fisherfolk. [103] Grazers (10, chubs) help keep coral reefs from being overgrown by macroalgae. [104]
For instance, barnacles on whales is an example of an ectosymbiotic relationship where the whale provides the barnacle with a home, a ride, and access to food. The whale is not harmed, but it also does not receive any benefits so this is also an example of commensalism. An example of ectosymbiotic bacteria is cutibacterium acnes. These bacteria ...
Coral reefs form complex marine ecosystems with tremendous biodiversity. Marine ecosystems are the largest of Earth 's aquatic ecosystems and exist in waters that have a high salt content. These systems contrast with freshwater ecosystems , which have a lower salt content.
Coral reefs are one of the most well-known marine ecosystems in the world, with the largest being the Great Barrier Reef. These reefs are composed of large coral colonies of a variety of species living together. The corals form multiple symbiotic relationships with the organisms around them. [7]
