An elephant’s trunk possesses a phenomenal sense of smell.
The upper nasal cavities have chemical and olfactory sensors in the form of millions of receptor cells. So sensitive is an elephant’s trunk that is more capable than a bloodhound’s nose and is said to be able to smell water from several miles away.
The head of the common warthog is large, with a mane down the spine to the middle of the back. Sparse hair covers the body. Its color is usually black or brown. Tails are long and end with a tuft of hair. Common warthogs do not have subcutaneous fat and the coat is sparse, making them susceptible to extreme environmental temperatures.
When an elephant feels uneasy, or is ambivalent about what to do next, he or she may use the trunk in a “touch-face” gesture, a “self-directed touching of the face, mouth, ear, trunk, tusk, or temporal gland, apparently to reassure and self-soothe.”
