Cats and owls are excellent examples of predators that use forward facing eyes when hunting their prey. Monkeys also have forward facing eyes that give them depth perception needed to swing and leap in their tree top habitat. Humans have forward facing eyes as well.

How many animals have forward facing eyes?
However, front-facing eyes are a highly evolved trait in vertebrates, and there are only three extant groups of vertebrates with truly forward-facing eyes: primates, carnivorous mammals, and birds of prey.
Do dogs have forward facing eyes?
Dogs have forward facing eyes, enabling them to spot movement ahead of them. In dim light they can dilate their pupils and they also possess a reflective layer - the tapetum - which helps dogs see at dusk and dawn.
Are primates the only animals with forward facing eyes?
All living primates have forward-facing eyes (Figure 1; Johnson, 1901; Cartmill, 1992). In this respect, primates more closely resemble cats and owls than many other mammals (e.g., squirrels or gazelles).
Do tigers have forward facing eyes?
Tigers have forward facing eyes rather than one on each side of their head. This provides binocular vision because each eye's field of vision overlaps creating a three dimensional image.
Do rats have forward facing eyes?
When the rat lifts its head, the eyes look forward: cross-eyed, so to speak. If the animal puts its head on one side, the eye on the lower side moves up and the other eye moves down.” says Jason Kerr. In humans, the direction in which the eyes look must be precisely aligned, otherwise an object cannot be fixated.
Do mice have forward facing eyes?
“This is surprising, because no one thought it would be the same in mice. Their eyes don't face forward, and they don't move their eyes to focus on objects,” said Haider, assistant professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory.
Are forward facing eyes predator?
Eyes that face forward on a skull suggest a predator. Forward facing eyes allow for binocular or stereoscopic vision, which allows an animal to see and judge depth. Predators need this depth perception to track and pursue prey. ... Animals with eyes that are located on the side of its head would suggest a prey animal.
Do crocodiles have front facing eyes?
Some animals, including, of course, humans, have evolved with forward-facing eyes in the front of their heads. Other animals have eyes that face sideways. ... Oh, and then there's crocodiles and alligators who have eyes on the top of their heads – all the better to eat you with.
Are humans prey or predators?
Their new study shows that humans are strange predators. Unlike other animals, we target adult prey in large numbers. That is a practice that can push populations of those prey into decline, the researchers warn. People mainly target — at least among wild mammals and fishes — prey that are old enough to reproduce.
Did T Rex have forward facing eyes?
But theropods, including tyranosaurs such as the famous T-rex, had forward-facing eyes. This gave them a high degree of binocular field of view. This means that tyrannosaurs would have had excellent depth perception to estimate the distance to prey and the timing of their attack.
Why do gorillas have forward facing eyes?
As daytime herbivores they probably have color vision, a useful adaptation for finding ripening fruits in treetops. Primates have forward facing eyes rather than one on each side of their head. This provides binocular vision because each eye's field of vision overlaps creating a three dimensional image.
Is a monkey an animal or primate?
primate, in zoology, any mammal of the group that includes the lemurs, lorises, tarsiers, monkeys, apes, and humans.
How do Tigers see humans?
Most tigers will only attack a human if they cannot physically satisfy their needs otherwise. Tigers are typically wary of humans and usually show no preference for human meat.
What color can rats not see?
They cannot see the colour red at all, although they can discern between shades of blue and green. Because rats and mice are nocturnal, i.e., active at night, the ability to perceive color would not be a useful advantage. Rats and mice are nearsighted, only able to focus on an object that is about one or two feet away.
Are rats and mice blind?
The truth is a little more nuanced than mice being outright blind, or practically blind. Mice can see pretty well, but don't have the best eyesight of the animal kingdom. Most of their focus is on finding food in small, cramped or dark spaces, so they don't have much of an eye for detail beyond a short range.
Do rodents have pupils?
Like the human pupil, the rat's pupil size is highly variable. Under dim light, the rat's pupil can reach a diameter of 1.2 mm (Block 1969). ... Pupil diameter changes can be very rapid in the rat: a contraction from 2 mm to 0.5 mm takes only half a second (Lashley 1932). Next, the light passes through the lens.
