 times they stay there until they die. This practice led some people to think that elephants went to special burial grounds to die.
The nose knows. An elephant's trunk is both an upper lip and a nose. There are 8 major muscles on each side of the trunk and 150,000 muscle fascicles (portions of muscles) for the entire trunk. There are no bones or cartilage in this unique appendage. An elephant's trunk is so strong it can push down trees and so agile that it can pick up a single piece of straw. Elephants also use their trunk like we use our hands: to grab, hold, pick up, reach, touch, pull, push, and throw.
The trunk is still a nose, too, and has two nostrils at the end that suck air up the long nasal passages and into the lungs. Elephants also use their trunks to drink, but the water doesn’t go all the way up the nose like a straw; instead, the elephant sucks water only part way up the trunk, curls it toward its mouth, tilts its head up, and lets the water from the trunk pour in.
Sounds of music. Elephants make many different sounds; humans cannot hear some of these sounds, as their frequency is too low for our ears. Elephants use these sounds to communicate with each other over long distances. Have you ever had your stomach growl at an unfortunate moment? Well, stomach growls are a welcome sound in elephant society; a stomach that makes loud rumbling and growling noises seems to signal to others that everything is “okay.”
The largest elephant on record was an adult male African elephant. He weighed about 24,000 pounds (10,886 kilograms) and was 13 feet (3.96 meters) tall at the shoulder! Most elephants don't get that large, but African bush elephants do grow larger than Asian elephants.
HABITAT AND DIET
Home is where the herd is. Asian elephants live in India, Nepal, and parts of Southeast Asia. Their habitat is scrub forest and rain forest, and they are often found along rivers during dry months.
African bush elephants are found in eastern, central and southern Africa, living in lowland and montane forests, flood plains, and all types of woodland and savanna. The smaller African forest elephants inhabit the Congo basin and western Africa in moist, semi-deciduous rain forests.
Elephants eat all types of vegetation, from grass and fruit to leaves and bark—about 165 to 330 pounds (75 to 150 kilograms) each day, which is about 4 to 6 percent of their body weight. They spend an average of 16 hours per day eating! Bush elephants are grazer-browsers and eat grasses, including sedges, flowering plants, leaves, shrubs, and small- to medium-size trees. Forest elephants are browser-frugivores and eat leaves, fruits, seeds, branches, and bark. Asian elephants are both browsers (feeding on shrubs and trees during the dry season and after heavy rains) and grazers (feeding on grass during the first part of the wet season). They can consume many species of plants, as well as twigs and bark. The choice of plants varies with seasons.
The elephants at the San Diego Zoo and the San Diego Zoo Safari Park eat less than their wild counterparts—about 125 pounds (57 kilograms) of food each day—because they don’t have to burn as many calories looking for food. Still, the adult male African elephants at the Safari Park need to eat over 70,000 calories each day! Our elephants are offered hay, herbivore pellets, acacia browse, celery, cucumbers, and lettuce daily. Elephants drink 20 to 50 gallons (75 to 190 liters) of water each day.
All elephants live in close social groups called herds, usually made up of related females and their offspring. The leader of the herd is known as the matriarch; she is usually the oldest and most experienced female in the group. The matriarch remembers where and how to find food and water, how to avoid predators, and the best places for shelter. She also keeps the younger elephants in line and teaches them how to behave in elephant society. In some cases the group may include one of the matriarch’s sisters and her offspring. When groups get too big, “bond groups” split off but maintain a loose association.
