Elephants are not only the largest land mammals on Earth; they are also among the most endearing: an irresistible mix of intelligence, dexterity, mystery and sheer power. Comprised of over 100,000 individual muscles, the elephant's trunk is the world's most versatile nose. At various times it functions as a hand, weapon, drinking straw, vacuum cleaner, snorkel and eating utensil. Combine this with a pair of tusks which are, in fact, the world's longest teeth and the elephant presents an extremely formidable face. These powerful pachyderms are able to adapt to almost any African habitat. In the Kunene desert, they trek for days in search of precious water to drink. In the rainforest of Ghana, the smaller, more agile elephants face different challenges. In rarely captured footage, the forest elephants are seen spraying themselves with half-chewed food and saliva to cool themselves down.
