Another important point to note is that disparity can only be used by animals who have frontal eyes like cats,
dogs, humans etc. For example, a rabbit has lateral eyes (on both sides of the head) and hence cannot use disparity
to sense depth. However, they have a wider view of the world than animals with frontal eyes. These kinds of
animals have much better ways of using movement cues to sense the depth. By evolution, it has been sees that
predators like humans, canines etc have frontal eyes since depth perception is extremely important for them to
hunt successfully. However animals lower in the food chain, herbivores like rabbit and deers usually have lateral
eye to get a larger field of view so that they are aware of a larger part of the environment and sense predators better.
