Animal partnerships refer to the cooperative relationships formed between different species, often for mutual benefit. These interactions can include symbiosis, where one species benefits without harming the other, or mutualism, where both species gain advantages. Examples include clownfish and anemones, where clownfish receive protection while anemones benefit from nutrients. Another common type of partnership is commensalism, where one species benefits and the other is neither helped nor harmed. An example is barnacles attaching to whales; barnacles gain mobility and access to food, while whales are largely unaffected. These partnerships play crucial roles in ecosystems, promoting biodiversity and stability.
