Deer have a great sense of hearing.
Deer are the only animals that have antlers. Deer have an excellent sense of smell, which allows them to detect predators from a long distance away. Deer lick their nose to keep it moist, which helps odor particles stick to it, improving their sense of smell. Deer have small teeth in the front of the bottom jaw, which they use for tearing and breaking apart food. They have no teeth in the front of the top jaw. Instead they have a hard palate, which is used in much the same way as teeth.
