By definition, symbiosis is the close and often long term interaction between two or more different species. The word symbiosis is derived from the Greek words, sym (together) and bio (life). German biologist Anton de Bary is the scientist typically credited with coining the term in the middle of the nineteenth century, though also an important contribution was made by his contemporary, Albert Bernhard Frank. Frank, however, instead used the term symbiotism. De Bary introduced the term to discuss lichens, which he discovered were parts of algae and fungi. On the contrary, Frank reported on the association between fungi and roots of forest trees, which he named mykorrhiza. Mycorrhiza is also a Greek word combined from the two words meaning fungus and roots. The association in mycorrhiza is a significant component of soil life and soil chemistry, and the plant roots characterized by it are from vascular plants.
De Bary defined symbiosis as the phenomenon in which unlike organisms live together. Therefore, the original definition of symbiosis was meant to include the entire gamut of close and long-term associations between two distinguished organisms, unaware of the harm or benefit caused by the interaction. Animals all over the world are involved in symbiotic relationships. The types of symbiotic relationships are mutualism, commensalism, and parasitism. ("Symbiosis." Wikipedia.

Foremost, in a mutualistic relationship, both organisms benefit. One example of a mutualistic relationship is that of the oxpecker (two species of bird which make up the family Buphagidae) and the zebra or rhinoceros. Oxpeckers land on zebras or rhinos and feed on ticks and other parasites that live on ...

...d insulates the body. Whales have a spinal column, a vestigial pelvic bone, and a four-chambered heart. The neck vertebrae are typically fused, trading flexibility for stability during swimming. ("Whale." Wikipedia. Wikimedia Foundation, 13 May 2014. Web. 15 May 2014).
A final example of a commensal relationship is a titan triggerfish. It is often referred to as giant triggerfish because of its size ad belongs to the Animalia kingdom and the balistidae family. It has the ability to develop and generate feeding opportunities for smaller fish. It can move large rocks that are too big for the small fish to move by themselves.

In essence, symbiosis is an important interaction amongst organisms. This is clearly evident in marine organisms. Without symbiotic relationships like commensalism, marine animals would not be surviving and maintaining as well as they are now.
