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.
When humans accommodate to a near object, they also converge their eyes and constrict their pupils. The combination of these three movements (accommodation, convergence and miosis ) is under the control of the Edinger-Westphal nucleus and is referred to as the near triad , or accommodation reflex .

In humans, brown is by far the most common eye color, with approximately 79% of people in the world having it. [35] Brown eyes result from a relatively high concentration of melanin in the stroma of the iris, which causes light of both shorter and longer wavelengths to be absorbed.

This type of eye is common in mammals, including humans. The simplest eyes are pit eyes. They are eye-spots which may be set into a pit to reduce the angle of light that enters and affects the eye-spot, to allow the organism to deduce the angle of incoming light. [1] Eyes enable several photo response functions that are independent of vision.
The condition also results when two eyes do not function together properly as described here. Most stereoblind persons with two healthy eyes do employ binocular vision to some extent, albeit less than persons with normally developed eyesight. This was shown in a study in which stereoblind subjects were posed with the task of judging the ...
The display of mirroring often begins as early as infancy, as babies begin to mimic individuals around them and establish connections with particular body movements. [3] The ability to mimic another person's actions allows the infant to establish a sense of empathy and thus begin to understand another person's emotions.
A starling, for example, has laterally placed eyes to cover a wide field of view, but can also move them together to point to the front so their fields overlap giving stereopsis. A remarkable example is the chameleon, whose eyes appear as if mounted on turrets, each moving independently of the other, up or down, left or right. Nevertheless, the ...
Some reptiles, such as the sand lizard of Europe, have eyespots; in the sand lizard's case, there is a row of spots along the back, and a row on each side. [12]Many species of cat, including Geoffroy's cats, jungle cats, pampas cats, and servals, have white markings, whether spots or bars, on the backs of their ears; it is possible that these signal "follow me" to the young of the species.
