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.
An alternative term, Peckhamian mimicry, has been suggested (after George and Elizabeth Peckham), [6] [7] [8] but it is seldom used. [a] Aggressive mimicry is opposite in principle to defensive mimicry, where the mimic generally benefits from being treated as harmful. The mimic may resemble its own prey, or some other organism which is ...
The walking leaf insects from the Indo-Pacific region resemble tree leaves in appearance and posture.In biology, mimesis (from ancient Greek μίμησις mímēsis, "imitation") [1] is a form of crypsis where living creatures mimic the form, colour and posture of their surroundings to avoid being noticed from their surroundings by predators depending on sight. [2]

In evolutionary biology, mimicry in plants is where a plant evolves to resemble another organism physically or chemically. Mimicry in plants has been studied far less than mimicry in animals . It may provide protection against herbivory , or may deceptively encourage mutualists, like pollinators , to provide a service without offering a reward ...
In evolutionary biology, mimicry in vertebrates is mimicry by a vertebrate of some model (an animal, not necessarily a vertebrate), deceiving some other animal, the dupe. [1] Mimicry differs from camouflage as it is meant to be seen, while animals use camouflage to remain hidden.
The term bionic then became associated with "the use of electronically operated artificial body parts" and "having ordinary human powers increased by or as if by the aid of such devices". [14] Because the term bionic took on the implication of supernatural strength, the scientific community in English speaking countries largely abandoned it.
The mechanism, analogous to Batesian mimicry, is found in insects such as the monarch butterfly. In another form, first noted by Edward B. Poulton in 1890, a less vulnerable part of an animal's body resembles a more vulnerable part, for example with deceptive eyespots or a false head that deflects attacks away from the real head, providing an ...
