There are a few different types of mimicry:

* Batesian mimicry: A harmless species evolves to look like a dangerous one. This is the classic example of a viceroy butterfly mimicking a monarch butterfly, which is poisonous to predators.

* Müllerian mimicry: Two or more poisonous or dangerous species evolve to look alike. This is beneficial because predators learn to avoid the pattern more quickly, increasing survival for all the mimics.

* Aggressive mimicry: A predator evolves to look like something harmless in order to lure prey. For example, some spiders use camouflage to resemble flowers, attracting unsuspecting insects.
