Structural – something to do with the ‘body’ of the organism. EG.
ADAPTATIONS

Structural – something to do with the ‘body’ of the organism. EG. Wings, claws, teeth, big ears.
Physiological – something to do with chemicals inside the organism. EG.

Physiological – something to do with chemicals inside the organism. EG. Poison in snakes/plants, pepsin in our stomachs which digest food quickly.
Behavioural – a behaviour change that benefits. EG.

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
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.
