What is mimicry

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

3 Types of Mimicry

  • Batesian Mimicry

  • Muellerian Mimicry

  • Self Mimicry


Batesian 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

Meullerian Mimicry

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


Self mimicry

Self Mimicry

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

Mimesis

    • This means the species is seen by predator but is mistaken for another organism
