Symbiosis

Symbiosis means "living together". Symbiotic relationships are very common in the ocean, especially among animals living on coral reefs. There are several kinds of symbiosis: "mutualism" is a partnership in which both animals benefit; "parasitism" is a relationship in which one animal benefits at the expense of the other; "commensalism" is a term used to cover all other kinds of symbiosis - usually relationships where one partner benefits, while the other is neither helped nor harmed.
