A giraffe's long neck allows it to feed where other animals can't, ensuring its food supply and the survival of its . Predatory animals like wolves or lions have eyes in the front of their heads which aid in hunting, while prey animals like rabbits or antelopes have eyes on the sides of their heads, which helps them better spot predators.
