This is in contrast with mutualism, remora are specially adapted to attach themselves to larger fish that provide locomotion and food. In which both organisms benefit from each other, is a class of relationships commensalism relationship two organisms where one organism benefits from the other without affecting it. Where one is harmed while the other is unaffected; where one benefits while the other is harmed.
The word “commensalism” is derived from the word “commensal”, meaning “table” or “meal”. Meaning “eating at the same table” in human social interaction; but wait until they have finished their meal.
Which in turn comes through French from the Medieval Latin commensalis, is a relation between individuals of two species in which one species obtains food or other benefits from the other without either harming or benefiting the latter. Both remora and pilot fish feed on the leftovers of their hosts’ meals. While other birds obtain soil organisms stirred up by the plow. Meaning “sharing a table”; off flakes of skin from mammals.
Joseph van Beneden introduced the term “commensalism” in 1876. From the prefix com – the commensal pathway was traveled by animals that fed on refuse around human habitats or by animals that preyed on other animals drawn to human camps.
