These are the forehead glands (on the forehead), the preorbital glands (below the eyes), the nasal glands (inside the nostrils), the interdigital glands (between the toes), the preputial gland (inside the foreskin of the deer's penis ), the metatarsal glands ...
In humans, the pupil is circular, but its shape varies between species; some cats, reptiles, and foxes have vertical slit pupils, goats and sheep have horizontally oriented pupils, and some catfish have annular types. [3] In optical terms, the anatomical pupil is the eye's aperture and the iris is the aperture stop.
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.

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 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 ...
Feral goats consist of many breeds of domestic goats, all of which stem from the wild goat (C. aegagrus). Although breeds can look different, they all share similar characteristics. Physically, both domestic and feral goats can be identified by their prominent straight horns (more prominent on male goats), rectangular pupils, and coarse hair.
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.
Their coats help them to withstand winter temperatures as low as −46 °C (−51 °F) and winds of up to 160 kilometres per hour (99 mph). Close-up of head. A male goat stands about 1 m (3.3 ft) at the shoulder to the waist and can weigh considerably more than the female (around 30% more in some cases).
