Camouflage and Mimicry

By: Michael Shulman and Eli Miloff


What is Camouflage?


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

  • 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


Camouflage


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:

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
