It derives from the Greek term mimetikos, "imitative", in turn from mimetos, the verbal adjective of mimeisthai, "to imitate". [1] "Mimicry" was first used in zoology by the English entomologists William Kirby and William Spence in 1823. [2] [3] Originally used to describe people, "mimetic" was used in zoology from 1851. [1]
The predatory species mediating indirect interactions between the mimic and the model is variously known as the [signal] receiver, dupe or operator. By parasitising the honest warning signal of the model, the Batesian mimic gains an advantage, without having to go to the expense of arming itself. The model, on the other hand, is disadvantaged ...
[9] Aggressive mimicry compared to a defensive form, Batesian mimicry. The mechanism is often called "Wolf in sheep's clothing". The model for an aggressive mimic can be a harmless species, in which case the 3 roles are disjunct, or the model can be the prey itself, in which case the arrangement is bipolar. [9]
The proportional gain compared to the total population of species 1 is g 1 = a 2 n / a 1 (a 1 +a 2) and similarly for species 2 g 2 = a 1 n / a 2 (a 1 +a 2) , giving the per head fitness gain of the mimicry when the predators have been fully educated. Hence, Müller concluded, the proportion g1:g2 was a 2 / a 1 : a 1 ...
Due to the drastic difference in average body size between the two phyla, vertebrates tend to mimic other living things, while invertebrates are much better able to mimic inanimate objects. [1] [10] [28] Large size makes any imprecision much more noticeable to the naked eye, slowing or preventing the evolution of mimicry. However, when a ...
Top: An ant in Mozambique Bottom: An ant-mimicking spider, Myrmarachne Ant mimicry or myrmecomorphy is mimicry of ants by other organisms; it has evolved over 70 times. Ants are abundant all over the world, and potential predators that rely on vision to identify their prey, such as birds and wasps, normally avoid them, because they are either unpalatable or aggressive.
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]
Nudibranch molluscs are the most commonly cited examples of aposematism in marine ecosystems, but the evidence for this has been contested, [37] mostly because (1) there are few examples of mimicry among species, (2) many species are nocturnal or cryptic, and (3) bright colours at the red end of the colour spectrum are rapidly attenuated as a ...
