Animal coloration From Wikipedia, the free encyclopedia (Redirected from Animal colouration ) A brilliantly-coloured Oriental Sweetlips fish ( Plectorhinchus vittatus ) waits while two boldly-patterned Cleaner Wrasse ( Labroides dimidiatus ) pick parasites from its skin. The spotted tail and fin pattern of the Sweetlips signals sexual maturity; the behaviour and pattern of the Cleaner fish signal their availability for cleaning service , rather than as prey Animal coloration is the general appearance of an animal resulting from the reflection or emission of light from its surfaces. The mechanisms for colour production in animals include pigments , chromatophores , structural coloration , and bioluminescence . Animal coloration has been a topic of interest and research in biology for well over a century. According to Charles Darwin 's 1859 theory of natural selection , [1] features such as coloration evolved by providing individual animals with a reproductive advantage. For example, individuals with slightly better camouflage than others of the same species would, on average, leave more offspring. [2] There are several separate reasons why animal coloration may evolve: Camouflage , enabling an animal to remain hidden from view Signalling to other animals, of the same or different species, including: Advertising , signalling services such as cleaning to animals of other species Sexual selection , signalling sexual status to other members of the same species

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
