Emsleyan mimicry was first proposed by M. G. Emsley [2] as a possible explanation for how a predator species could learn to avoid an aposematic phenotype of potentially dangerous animals, such as the coral snake, when the predator is likely to die on its first encounter.
Mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species. Often, mimicry functions to protect from predators. [11] Mimicry systems have three basic roles: a mimic, a model, and a dupe.

Defensive or protective mimicry enables organisms are able to avoid encounters that would be harmful to them by deceiving enemies by appearing to be something that they are not. For example, mantis shrimps spread their powerful front limbs to threaten rivals in a behaviour called the "meral spread". [ 6 ]

Aggressive mimicry stands in semantic contrast with defensive mimicry, where it is the prey that acts as a mimic, with predators being duped. Defensive mimicry includes the well-known Batesian and Müllerian forms of mimicry, where the mimic shares outward characteristics with an aposematic or harmful model. In Batesian mimicry, the mimic is ...
Complicated forms of aggressive mimicry have also been observed in fish, creating a system that resembles Batesian mimicry. The false cleanerfish , Aspidontus taeniatus , is a fin-eating blenny that has evolved to resemble a local species of cleaner wrasse, Labroides dimidiatus , which engages in mutualistic cleaning with larger fish.
Locomotor mimicry is a subtype of Batesian mimicry in which animals avoid predation by mimicking the movements of another species phylogenetically separated. [1] This can be in the form of mimicking a less desirable species or by mimicking the predator itself. [1] Animals can show similarity in swimming, walking, or flying of their model animals.
