The interaction between red-billed oxpecker and impala is mutualism. The interaction between titan triggerfish and smaller fishes is commensalism.
<h3>Mutualism and Commensalism</h3>
Mutualism is a form of symbiotic interaction between two organisms in which both organisms benefit from the interaction without being negatively affected in any way.
Commensalism, on the other hand, is a form of interaction between two organisms in which one (the commensal) gains and the other neither benefits nor lose from the interaction.
The red-billed oxpecker gets its food off the fur of the Impala. The tick that serves as food for red-billed oxpecker is a parasite that harms the impala. Thus, the red-billed oxpecker gets its food while the impala gets the ticks that can harm it removed. A mutually beneficial relationship.
The activities of the Titan triggerfish benefit smaller fishes. The Titan triggerfish neither benefits nor gets harmed in the interaction. A form of commensalism.
