Commensalism represents an interaction in which one species benefits while the other remains unharmed. There are four recognized forms of commensalism.
Commensalism is a type of symbiotic relationship in which one organism benefits while the other organism is not affected either positively or negatively. In other words, the commensal organism benefits from the relationship, while the host organism is neither helped nor harmed.
commensalism, in biology, a relationship between individuals of two species in which one species obtains food or other benefits from the other without either harming or benefiting the latter. The commensal—the species that benefits from the association—may obtain nutrients, shelter, support, or locomotion from the host species, which is ...
A commensal species benefits from another species by obtaining locomotion, shelter, food, or support from the host species, which neither benefits nor is harmed. Commensalism ranges from brief interactions between species to life-long symbiosis.
An interesting example of commensalism is that of the pseudoscorpion. Pseudoscorpions are very tiny scorpions (less than a centimeter) that hitch rides on much larger insects. Seen in the photo above, a pseudoscorpion is attached to the leg of a much larger fly.
Examples include gut bacteria and flora found on human skin. In many cases, microbiota are mutualistic more than commensal. For example, gut bacteria get food and shelter from their host, while releasing vitamins essential for nutrition or breaking down molecules the host cannot digest.
Commensalism is a symbiotic relationship between two species, where one species benefits while the other is neither helped nor significantly harmed. In other words, it is a win-neutral situation. The best example of commensalism is sea barnacles attached to the skin of whales.

Examples of commensal relationships. Domestic and feral pigeons (Columba livia domestica) are commensals, having lived alongside humans for thousands of years after being domesticated from the rock dove (Columba livia). Due to its range being expanded with human assistance, the pigeon has a cosmopolitan distribution. [6]
The simplest example of commensalism is a bird making a nest in a tree. The tree provides shelter and protection to the bird without getting significantly harmed or affected by the bird. Another typical example is the cattle egrets (birds) that feed upon the insects stirred up by the feeding cattle.
