In zoology, most predatory animals employ binocular vision. Morphologically, these animals have eyes situated in front; hence, they directly see what is ahead. Each eye sees a separate image, which then combines into one composite image. This type of vision also enables better depth perception. It makes animals see in 3D mode. Thus, these animals are better at perceiving relative distances and depth. Examples of animals using binocular vision are eagles, humans, and snakes.
