2. What is Camouflage?

3.  The act, means, or result of concealment that allows otherwise visible animals to remain unnoticed by blending in with their environment

4. Camouflage

5.  Camouflage is essentially a form of visual mimicry, where the species mimics its environment

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=rel ated

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
