　　largest living land animal, characterized by its long trunk (elongated upper lip and nose), columnar legs, and huge head with temporal glands and wide, flat ears. Elephants are grayish to brown in colour, and their body hair is sparse and coarse. They are found most often in savannas, grasslands, and forests but occupy a wide range of habitats, including deserts, swamps, and highlands in tropical and subtropical regions of Africa and Asia.

　　The African savanna, or bush, elephant (Loxodonta africana) weighs up to 8,000 kg (9 tons) and stands 3 to 4 metres (10 to 13 feet) at the shoulder. The African forest elephant (Loxodonta cyclotis), which lives in rainforests, was recognized as a separate species in 2000 and is smaller than the savanna elephant. It has slender, downward-pointing tusks. The common belief that there existed “pygmy” and “water” elephants has no basis; they are probably varieties of the African forest elephants.

　　The Asian elephant (Elephas maximus) weighs about 5,500 kg and has a shoulder height of up to 3.5 metres. The Asian elephant includes three subspecies: the Indian, or mainland (E. m. indicus), the Sumatran (E. m. sumatranus), and the Sri Lankan (E. m. maximus). African elephants have much larger ears, which are used to dissipate body heat.

　　The Asian elephant’s natural habitat is the forest so the destruction of forests is a major concern. But, as the forest is reduced, the elephant finds itself in farmland and villages. This brings with it other, social, problems.

　　Only certain male Asian elephants carry ivory. While its tusks are not as large as those of its African counterpart, Asian elephant ivory is perceived to be superior in quality. As a result, poaching is still prevalent in some areas

　　The variety of issues that surround elephant conservation require that the corresponding government departments (of forestry, landuse planning, transport, law enforcement, etc.) all have a role to play. And it is in this multi-dimensional context that NGOs must find ways to support government strategy.

　　An elephant is the largest terrestrial mammal in the world, usually a family unit, and sometimes a few elephants gather together to form hundreds of elephants. African elephants are the leaders of the female, the time of day activities, the route of action, foraging sites, habitats and other places to listen to the female elephant command, the Asian elephant is the opposite, by adult male elephant bear the responsibility to defend the family security. The cortex is very thick, but the skin is very thin, so it is often used to prevent mosquito bites. Ivory is an important weapon against the enemy's

　　[1] the elephant ancestors in the tens of millions of years ago appeared on earth. Elephant family has been very prosperous, is one of the most dominant group of animals on earth, has been found more than 400 kinds of fossils. However, due to the history of climate and human factors, resulting in fewer and fewer types of ethnic groups. At present, there are only 2 genera and 3 species on the earth, such as the Asian elephant, the African elephant and the African forest elephant, and they are also under serious threat.

　　An elephant family is ruled by a matriarch (older female), and generally consist of her female offspring and their young

　　In Africa, a basic family unit consists of six to twelve animals, but families of twelve to twenty elephants are quite common

　　An elephant family will split depending on the size of the family, the amount of available food, and how well they are getting along.

　　When the matriarch dies, one of the oldest offspring takes her place.

　　The mating patterns of elephants offer us key insights into family structures and life cycle behaviours. Mating patterns are unique since elephants do not confine mating to a specific time of year. The situation which develops involves the bull pursuing the cow until she is ready for mounting. When the bull elephant desires sexual activity, he approaches the matriarch-led herd. Once the bull finishes his business he joins the bachelor herd or leaves on his own. It is this male-leaving behaviour that highlights the matriarch elephant family.

　　An elephant family is led by a matriarch, with the matriarch being the oldest and most experienced of the herd. The matriarchal society consists of her female offspring and their young. In some cases it may include one of the matriarch's sisters and her offspring as well. It is this close contact and relationship allows the rest of the elephant to acquire knowledge to be used when needed.

　　A basic African family unit contains six to twelve members. However, keep in mind that families of twelve or more elephants are quite common in certain areas.

　　Males as they grow older and approach puberty gradually become more independent from the family group. This involves primarily spending more time on the outskirts of the group. Eventually, the males leave the family and join with other males of different ages in a band of bulls.

　　Of the two different groups--female family groups and bull bands--the female group appears to be the enduring social unit. Often times when groups split apart, they maintain close association between each other; this include travelling together throughout the range. These related groups have been coined 'bond groups' by Joyce Poole and Cynthia Moss.

　　It is possible that these bond groups form larger units that have been called clans. Obviously, this is very difficult to study as well as to document as we are incapable of speaking and hearing as Elephants do. Thus, we must rely upon observations of greetings ceremonies that require an in-depth longitudinal study. A major problem for this type of ecological research is the fact that subjects are often murdered for their ivory.

　　After a indeterminate amount of time part of the group will split off to form a new family. This seems to depend on both environmental and social influences. Such as, how well the family members are getting along and the amount of food that is available to support the group. In times of food shortage families typically will split apart to maximize the possibility for survival.

　　When a matriarch dies, one of her elder offspring often takes the 'throne'.
