What is Camouflage? • The act, means, or result of concealment that allows otherwise visible animals to remain unnoticed by blending in with their environment
Camouflage • Camouflage is essentially a form of visual mimicry, where the species mimics its environment
Camouflage • Camouflage is essentially a form of visual mimicry, where the species mimics its environment • According to Natural Selection, camouflage is a characteristic increases a species chance of survival and reproduction and therefor is passed on
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
3 Types of Mimicry • Batesian Mimicry • Muellerian Mimicry • Self Mimicry
Batesian Mimicry • When two or more species are similar in appearance, but only one is equipped with spines, stingers, or toxic chemistry
Meullerian Mimicry • When two unpalatable (distasteful, indigestible) species are mimics of each other with conspicuous coloration
Self Mimicry • When animals have a certain structural body part that mimics bigger and more intimidating animals during an attack to aid their survival
Example of Camouflage • Here is an example of Camouflage demonstrated by the Peacock Flounder: http://www.youtube.com/watch?v=__XA6B41SQQ&feature=related
