MIMICRY

Is the similarity of one species to another which protects one or both. 

MIMICRY

Is the similarity of one species to another which protects one or both. 

This similarity can be in appearance, behaviour, sound, scent and even location, with the mimics found in similar places to their models.

MIMICRY

In Batesian mimicry the mimic shares signals similar to the model, but does not have the attribute that makes it unprofi table to predators (e.g. unpalatability). In other words, a Batesian mimic is a sheep in wolf’s clothing.

BATESIAN MIMICRY

Müllerian mimicry describes a situation where two or more species have very similar warning or aposematic signals and both share genuine anti-predation attributes (e.g. being unpalatable).

 If two species were confused with one another by a common predator, individuals in both would be more likely to survive.

MULLERIAN MIMICRY

Müllerian mimicry describes a situation where two or more species have very similar warning or aposematic signals and both share genuine anti-predation attributes (e.g. being unpalatable).

 If two species were confused with one another by a common predator, individuals in both would be more likely to survive.

Firstly, both the mimic and the model benefit from the interaction, which could thus be classified as mutualism.
