  8. What is Mimicry? • Mimicry: A structural adaptation in which a harmless species resembles a harmful species in color or structure (Textbook) • The similarities of one species to another which protects one or both

  9. 3 Types of Mimicry • Batesian Mimicry • Muellerian Mimicry • Self Mimicry

  10. Batesian Mimicry • When two or more species are similar in appearance, but only one is equipped with spines, stingers, or toxic chemistry

  11. Meullerian Mimicry • When two unpalatable (distasteful, indigestible) species are mimics of each other with conspicuous coloration

  12. Self Mimicry • When animals have a certain structural body part that mimics bigger and more intimidating animals during an attack to aid their survival

  13. Example of Camouflage • Here is an example of Camouflage demonstrated by the Peacock Flounder: http://www.youtube.com/watch?v=__XA6B41SQQ&feature=related

  16. The Mimic Octopus • http://www.videobash.com/video_show/the-incredible-mimic-octopus-399991

  17. Mimesis • An intermediate process between camouflage and mimicry • Mimesis: The process in which the mimic takes on the properties of a specific organism • This means the species is seen by predator but is mistaken for another organism
