In the simplest case, as in Batesian mimicry, a mimic resembles a model, so as to deceive a dupe, all three being of different species. A Batesian mimic, such as a hoverfly, is harmless, while its model, such as a wasp, is harmful, and is avoided by the dupe, such as an insect-eating bird. Birds hunt by sight, so the mimicry in that case is ...
An eyespot (sometimes ocellus) is an eye-like marking. They are found in butterflies, reptiles, cats, birds and fish. Eyespots could be explained in at least three different ways. They may be a form of mimicry in which a spot on the body of an animal resembles an eye of a different animal, to deceive potential predator or prey species.
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 ...
This imitates the structure of a moth's eye. [ 120 ] [ 121 ] Notable figures such as the Wright Brothers and Leonardo da Vinci attempted to replicate the flight observed in birds. [ 122 ] In an effort to reduce aircraft noise researchers have looked to the leading edge of owl feathers, which have an array of small finlets or rachis adapted to ...
Eyespots of foureye butterflyfish (Chaetodon capistratus) mimic its own eyes, which are camouflaged with a disruptive eye mask, deflecting attacks from the vulnerable head. In zoology, automimicry, Browerian mimicry, or intraspecific mimicry, is a form of mimicry in which the same species of animal is imitated. There are two different forms.
The folds mimic the natural creases found in leaves, channeling more light into the cell. The researchers claimed in 2015 that the leaf-like cells generated 47 percent more electricity than those ...
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 ...
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 separate, or the model can be the prey itself, in which case there are only 2 species involved.
