Types of Mimicry |
Mimicry meaning in biology, says that it is an evolved resemblance that exists between an organism and another unknown subject. Most of the time, the unknown subject is found to be an organism that belongs to a different species. Mimicry is something that can evolve between different species or different individuals of the same species. Mimicry is responsible for protecting different species from predators, thus making it an antipredator adaptation. One can get a clear idea of the meaning of mimicry from this paragraph.
Mimicry starts evolving when a receiver such as a predator starts perceiving the similarity between a mimic, the organism that is believed to have a resemblance (mimic meaning in biology) and a model, the organism which the mimic resembles, and as a result, the predator aims to change the behaviour of the model in a particular way that will give some selective advantage for the mimic. The resemblances that tend to evolve in mimicry are of many types, such as visual, acoustic, chemical, tactile or electric or sometimes the combinations of these sensory modalities.
Mimicry of organisms is most probably clear from the above paragraphs where we explained mimicry meaning. Now let’s discuss the different types of mimicry that exist in nature. We will discuss each in a brief way.
The edible species' deceptively similar colour patterns would give protection from the same predators. Batesian mimicry is named after its discoverer, and it occurs when a vulnerable creature shows a striking likeness to a toxic and visible one.
The phenomenon of automimicry refers to how certain members of a species benefit from their likeness to other members of the same species. Although defenceless, males of many bees and wasps are protected from predators by their similarity to females with stingers. Some butterflies can protect themselves from predators by absorbing, tolerating, and retaining toxins from the plants they feed on while still juvenile (larval). Individuals or even subpopulations of these butterflies may not gain such protection as a result of feeding on nonpoisonous plants, but predators that sampled protected individuals of the same species avoid them.
In some cases, it is advantageous for a predator to look like its prey, or for a parasite to look like its host. Aggressive mimicry, which is well described as "a wolf in sheep's clothing," is devoid of warning signals. In order to gain an edge over the model or a third species that interact with the model, the mimic adopts certain of its model's recognition marks.
Once the predator has learned to avoid the specific colour pattern with which it came into contact for the first time, it will avoid any other patterned species, both edible and non-edible. The predator's initial learning experience frequently results in death or harm to the inedible individual who delivered the lesson; thus, the species that informs the predator of its inedibility bears some cost. Evidence suggests that certain predators have little or no hereditary recognition of noxious or inedible species; instead, each individual learns about noxious or inedible species by sampling them. Other inedible species that resemble the first, on the other hand, do not need to sacrifice individuals to teach the same predator, and the number of individuals sacrificed in learning the total predator population is dispersed throughout all species that share the same warning pattern. Müllerian mimicry refers to the tendency of inedible or toxic species to resemble one another.
