Giraffes have good eyesight and hearing to avoid predators (usually lions) from eating them. Most lions will avoid giraffes as their long legs and hooves can be lethal to an attacking lion. The giraffe is a hoofed animal and doesn't have claws. It is an even-toed ungulate mammal.

In some cases there is. Some examples of this are certain species of bats which have very large ears, and super-sensitive hearing. Elephants also have very large ears, and exceptional hearing, though they are also able to pick up low frequency vibrations using their trunk and feet, which are packed with special receptors. On the other hand, owls, which literally just have ear-holes with feather disks to funnel sound into them, have some of the best hearing in the animal kingdom. Generally, if the shape of the ear looks something like a funnel, or if the shape of the ear or something around it looks as though it would direct sound into the ear, the animal will have good hearing.
