Question
Among animals, the predators (like lions) have their eyes facing forward at the front of their heads, whereas the animals of prey (like rabbit) usually have eyes at the sides of their head. Why is this so?
Solution
Predators, such as lions, have their eyes facing forward in the front of their heads because this enables them to judge the distance of their prey accurately and catch them easily.
Animals of prey, such as rabbits, usually have eyes on the sides of their head because this enables them to view a larger area. They can, therefore, see potential predators in a large area around them and try to escape.
