I want to know the answer to the following question:
What organisms are described as living on the surface of whales?
All the background I'm provided with is that "Examples of this include ectoparasites such as lice, commensal ectosymbionts such as the barnacles that attach themselves to the jaw of baleen whales, and mutualist ectosymbionts such as cleaner fish.". Is that enough to answer the question?
