The distinction between aggressive mimicry and predator camouflage depends on the signal given to the prey, not easily determined. Aggressive mimicry is a form of mimicry in which predators , parasites , or parasitoids share similar signals , using a harmless model, allowing them to avoid being correctly identified by their prey or host .
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.
For example, a mantid captures prey with its forelegs and they are optimized for grabbing prey of a certain size. Mantids are reluctant to attack prey that is far from that size. There is a positive correlation between the size of a predator and its prey. [28] A predator may assess a patch and decide whether to spend time searching for prey in ...
In aggressive mimicry a predator has the appearance of a harmless organism or object attractive to the prey; when the prey approaches, the predator attacks. An animal defending against a predator may engage in either " fight or flight " or " tend and befriend " in response to predator attack or threat of attack, depending on its estimate of the ...
The relationships among mimics can become complex. For example, the poison fangblenny Meiacanthus spp. have hollow canines and poison glands, and are avoided by predatory fish. The blenny Plagiotremus townsendi resembles Meiacanthus and is eaten by a variety of predators, so it is a Batesian mimic in their case: but it is avoided by the ...

The dominant post-encounter defensive behaviour can depend on whether the predator has also detected the prey and how far away the two animals are from one another. [ 3 ] [ 13 ] Varying levels of predatory imminence, even in post-encounter situations, can affect the expressed defensive behaviour. [ 13 ]
