An example of mutualism is the relationship between the ocellaris clownfish that dwell among the tentacles of Ritteri sea anemones. The territorial fish protects the anemone from anemone-eating fish, and in turn, the anemone stinging tentacles protect the clownfish from its predators .
Ectosymbiosis is defined as a symbiotic relationship in which one organism lives on the outside surface of a different organism. [3] 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.
Microbial symbiosis in marine animals was not discovered until 1981. [3] In the time following, symbiotic relationships between marine invertebrates and chemoautotrophic bacteria have been found in a variety of ecosystems, ranging from shallow coastal waters to deep-sea hydrothermal vents. Symbiosis is a way for marine organisms to find ...
The six possible types of symbiotic relationship, from mutual benefit to mutual harm. The six possible types of symbiosis are mutualism, commensalism, parasitism, neutralism, amensalism, and competition. [16] These are distinguished by the degree of benefit or harm they cause to each partner. [17]
Fungi's relationship to plants in the form of mycelium evolved from parasitism and commensalism. Under certain conditions species of fungi previously in a state of mutualism can turn parasitic on weak or dying plants. [24] Likewise the symbiotic relationship of clown fish and sea anemones emerged from a commensalist relationship.
Symbiotic relationships generally fall into the categories of mutualism, commensalism, parasitism/predation, amensalism, or competition, although other categorizations may be used to describe more complex or uncommon interactions. The relationship between clownfish and anemones is one example of a mutualistic symbiosis. [10]
An extreme example would be an organism who gains from a relationship without giving anything, such as an insect that feeds on nectar without contributing to pollination. [7] Cheaters are thought to destabilize mutualistic relationships, both when they arrive as a third exploitative party and when they result as mutants within pre-existing ...
Examples of photosymbiotic relationships include those in lichens, plankton, ciliates, and many marine organisms including corals, fire corals, giant clams, and jellyfish. [ 2 ] [ 3 ] [ 4 ]
