When you think “elephant,”you probably think “trunk.” An adult African elephant’s trunk is about seven feet (two meters) long! It’s actually an elongated nose and upper lip. Like most noses, trunks are for smelling. But they’re also for touching and grasping.
When an elephant drinks, it sucks as much as 2 gallons (7.5 liters) of water into its trunk at a time. Then it curls its trunk under, sticks the tip of its trunk into its mouth, and blows. Out comes the water, right down the elephant’s throat.
Since African elephants live where the sun is usually blazing hot, they use their trunks to help them keep cool. First they squirt a trunkful of cool water over their bodies. Then they often follow that with a sprinkling of dust to create a protective layer of dirt on their skin (think elephant sunscreen!).
Elephants pick up and spray dust the same way they do water—with their trunks. Elephants also use their trunks as snorkels when they wade in deep water.
An elephant’s trunk is controlled by many muscles. Two fingerlike parts on the tip of the trunk allow the elephant to perform delicate maneuvers such as picking a berry from the ground or plucking a single leaf off a tree. The elephant can also use its trunk to grasp an entire tree branch and pull it down to its mouth. Elephants also use their trunks to yank up clumps of grasses and shove the greenery into their mouths.
When an elephant gets a whiff of something interesting, it sniffs the air with its trunk raised up like a submarine periscope. If threatened, an elephant will also use its trunk to make loud trumpeting noises as a warning.
Elephants are social creatures. They sometimes “hug” by wrapping their trunks together in displays of greeting and affection. Elephants also use their trunks to help lift or nudge an elephant calf over an obstacle, to rescue a fellow elephant stuck in mud, or to gently raise a newborn elephant to its feet. And just as a human baby sucks its thumb, an elephant calf often “sucks its trunk” for comfort.
Hunting has been a major cause of the decline in elephant populations.
Elephants need a large amount of habitat because they eat so much. Humans have become their direct competitors for living space. Human populations in Africa and Asia have quadrupled since the turn of the century, the fastest growth rate on the planet. Forest and savanna habitat has been converted to cropland, pastureland for livestock, and timber for housing and fuel.
Humans do not regard elephants as good neighbors. When humans and elephants live close together, elephants raid crops, and rogue elephants (aggressive male elephants during the breeding season) rampage through villages. Local people shoot elephants because they fear them and regard them as pests. Some countries have established culling programs: park officials or hunters kill a predetermined number of elephants to keep herds manageable and minimize human-elephant conflicts.
