Mimicry/Camouflage Notes

Data Analysis

Reading/AnnotationSlide3

What is camouflage?the use of any combination of materials or coloration for concealment, either by making animals or objects hard to see (

crypsis

), or by disguising them as something else (mimicry)Slide4

What is Mimicry?mimicry is the similarity of one species to another which increases the fitness one or both species in areas where they are both

found

It is the result of the environment selecting for that similarity over many generationsSlide12

What do we call organisms involved in mimicry?Mimics are the organisms that have evolved in imitation of something else

Models are the species that are imitatedSlide13

Types of MimicryBatesian: the mimic shares signals similar to the model, but does not have the attribute that makes it undesirable to predatorsSlide14

Types of MimicryMullerian: when two or more species have very similar warning signals and both share genuine anti-predation attributes (more likely predators will learn to avoid them)Slide15

Types of MimicryMertensian: unusual cases where deadly prey mimic a less dangerous speciesSlide16

Types of MimicryWasmanian: the mimic resembles a model along with which it lives in a nest or colonySlide17

Types of MimicryGilbertian: potential host/prey drives away its parasite/predator by mimicking itSlide18

Types of MimicryLuring Mimicry: predator employing signals which draw its potential prey towards it by the promise of foodSlide19

Types of MimicryBrood-Parasite: a situation where a parasite mimics its own hostSlide20

Types of MimicryWicklerian: the mimic resembling a species that is a

mutualist

of the modelSlide21

Types of MimicryCryptic: the predator mimics an organism that its prey is indifferent toSlide22

Types of MimicryInter-sexual: the male of a species mimic the female of the species to sneak

matings

with the femaleSlide23

Worksheet20 minutes to complete, it will be collected

You may

quietly

discuss with a neighbor

Match the scenarios described with the type of mimicry we discussed today

I am here to helpSlide24

ExampleAustralian Cuttlefish (a relative of the Octopus), can be alpha-males, beta-males, and females. Alpha-males fight for the rights to a harem of females. Beta-males, instead of fighting, pretend to be females, and stay with the harem while the alphas are fighting, and then have sex with them. Slide25

This is an example of inter-sexual mimicry because a member of one gender is the model for a mimic of the other.Slide26
