Parabiosis commensalism is a type of symbiotic relationship in which one organism benefits from the relationship while the other is neither helped nor harmed. In this type of commensalism, one organism, known as the commensal, benefits from the association by using the resources or shelter provided by the other organism, known as the host, without affecting the host in any significant way. This type of relationship is common in nature and can be seen in various species, such as barnacles attaching themselves to whales or birds nesting in trees. **
