A core aspect of studies in this area is the division of eye movements into the rapid movement of the eyes , and the focus of the eyes on a point (fixations). Several factors can influence eye movement in scene viewing, including the task and knowledge of the viewer (top-down factors), and the properties of the image being viewed (bottom-up ...
Even without moving their eyes, some birds have a 360-degree field of view. Some other animals – usually, but not always, predatory animals – have their two eyes positioned on the front of their heads, thereby allowing for binocular vision and reducing their field of view in favor of stereopsis.

[3] In optical terms, the anatomical pupil is the eye's aperture and the iris is the aperture stop.
Few people have spent time gazing into a sheep’s eyes, but if you have, you may have noticed something very strange about their pupils. Instead of being round, as is the case with humans, they ...
A vergence is the simultaneous movement of both eyes in opposite directions to obtain or maintain single binocular vision. [1] When a creature with binocular vision looks at an object, the eyes must rotate around a vertical axis so that the projection of the image is in the centre of the retina in both eyes.
Their force can devastate forests and even demolish buildings. It would seem wise to avoid avalanche-prone areas, yet many animals continually risk living in these
The goat or domestic goat (Capra hircus) is a species of goat-antelope that is mostly kept as livestock. It was domesticated from the wild goat (C. aegagrus) of Southwest Asia and Eastern Europe. The goat is a member of the family Bovidae, meaning it is closely related to the sheep. It was one of the first animals to be domesticated, in Iran ...
