Barnacle and Whale Commensalism
Definition
This is a type of commensalism where barnacles attach themselves to the skin of whales. The barnacles benefit by getting transportation and more access to food sources, while the whale is neither harmed nor helped.
Analogy
It's like hitching a ride on a bus. The bus (whale) goes about its route unaffected, while you (barnacle) get to your destination without having to walk.
