THE ELEPHANT - EL ELEFANTE

The elephants (Elephantidae) are a family in the order Proboscidea in the class Mammalia. They were once classified along with other thick skinned animals in a now invalid order, Pachydermata. There are three living species: the African Bush Elephant, the African Forest Elephant (until recently known collectively as the African Elephant), and the Asian Elephant (also known as the Indian Elephant). Other species have become extinct since the last ice age, which ended about 10,000 years ago, the Mammoth being the most well-known of these.
The word "elephant" has its origins in the Greek ἐλέφας, meaning "ivory" or "elephant".
Elephants are mammals, and the largest land animals alive today. The elephant's gestation period is 22 months, the longest of any land animal. At birth it is common for an elephant calf to weigh 120 kg (265 lb). An elephant may live as long as 70 years, sometimes longer. The largest elephant ever recorded was shot in Angola in 1956. This male weighed about 12,000 kg (26,400 lb), with a shoulder height of 4.2m (13.8 ft), a metre (3 ft 4 in) taller than the average male African elephant. The smallest elephants, about the size of a calf or a large pig, were a prehistoric species that lived on the island of Crete during the Pleistocene epoch.
Elephants are symbols of wisdom in Asian cultures, and are famed for their exceptional memory and high intelligence, rivalled only by cetaceans and hominids.
Elephants are increasingly threatened by human intrusion. Between 1970 and 1989, the African elephant population plunged from 1.3 million to about 600,000; the current population is estimated to be between 400,000 and 660,000. The elephant is now a protected species worldwide, with restrictions in place on capture, domestic use, and trade in products such as ivory. Elephants generally have no natural predators, although lions may take calves and occasionally adults. In some areas, lions may regularly take to preying on elephants.

African Elephant

The Elephants of the genus Loxodonta, known collectively as African elephants, are currently found in 38 countries in Africa.

African elephants are distinguished from Asian elephants in several ways, the most noticeable being their ears. Africans' ears are much larger and are shaped - some note - like the continent of their origin. The African is typically larger than the Asian and has a concave back. Both African males and females have external tusks and are usually less hairy than their Asian cousins.
African elephants have traditionally been classified as a single species comprising two distinct subspecies, namely the savanna elephant (Loxodonta africana africana) and the forest elephant (Loxodonta africana cyclotis), but recent DNA analysis suggests that these may actually constitute distinct species. While this split is not universally accepted by experts a third species of African elephant has also been proposed.

Under the new two species classification, Loxodonta africana refers specifically to the Savanna Elephant, the largest of all elephants. In fact, it is the largest land animal in the world, standing up to 4 m (13 ft) at the shoulder and weighing approximately 7,000 kg (7.7 tons). The average male stands about 3 m (10 ft) tall at the shoulder and weighs about 5500–6000 kg (6.1 - 6.6 tons), the female being much smaller. Most often, Savanna Elephants are found in open grasslands, marshes, and lakeshores. They range over much of the savanna zone south of the Sahara.

The other postulated species is the Forest Elephant (Loxodonta cyclotis). Compared with the Savanna Elephant, its ears are usually smaller and rounder, and its tusks thinner and straighter and not directed outwards as much. The Forest Elephant can weigh up to 10,000 lb 4,500 kg (10,000 lb) and stand about 10 ft (3 m) tall. Much less is known about these animals than their savanna cousins because environmental and political obstacles make them very difficult to study. Normally, they inhabit the dense African rain forests of central and western Africa, though occasionally they roam the edges of forests and so overlap the territories of the Savanna elephants and breed with them. In 1979, Iain Douglas-Hamilton estimated the continental population of African elephants at around 1.3 million animals. This estimate is controversial and is believed to be a gross overestimate, but it is very widely cited and has become a de facto baseline that continues to be incorrectly used to quantify downward population trends in the species. Through the 1980s, Loxodonta received worldwide attention due to the dwindling numbers of major populations in East Africa, largely as a result of poaching. Today, according to IUCN’s African Elephant Status Report 2002 there are approximately between 400,000 and 650,000 African elephants in the wild. Although this estimate only covers about half of the total elephant range, experts do not believe the true figure to be much higher, as it is unlikely that large populations remain to be discovered. By far the largest populations are now found in Southern and Eastern Africa, which together account for the majority of the continental population. According to a recent analysis by IUCN experts, most major populations in Eastern and Southern Africa are stable or have been steadily increasing since the mid-1990s, at an average rate of 4.5% per annum.

Elephant populations in West Africa, on the other hand, are generally small and fragmented, and only account for a small proportion of the continental total. Much uncertainty remains as to the size of the elephant population in Central Africa, where the prevalence of forest makes population surveys logistically difficult, but poaching for ivory and bushmeat is believed to be intense through much of the region.

Asian Elephant

The Asian elephant is smaller than the African. It has smaller ears, and typically, only the males have large external tusks.
The world population of Asian elephants - also called Indian Elephants or Elephas maximus - is estimated to be around 60,000, about a tenth of the number of African elephants. More precisely, it is estimated that there are between 38,000 and 53,000 wild elephants and between 14,500 and 15,300 domesticated elephants in Asia with perhaps another 1,000 scattered around zoos in the rest of the world. The Asian elephants' decline has possibly been more gradual with the causes primarily being poaching and habitat destruction by human encroachment.

Elephant In Sri Lanka
There are several subspecies of Elephas maximus and some have been identified only using molecular markers. The first subspecies is the Sri Lankan Elephant (Elephas maximus maximus). Found only on the island of Sri Lanka, it is the largest of the Asians. There are only an estimated 3,000-4,500 members of this subspecies left today in the wild, although no accurate census has been carried out in the recent past. Large males can weigh upward to 5,400 kgs (12,000 lb) and stand over 3.4 m (11 ft) tall. Sri Lankan males have very large cranial bulges, and both sexes have more areas of depigmentation than are found in the other Asians. Typically, their ears, face, trunk, and belly have large concentrations of pink-speckled skin. There is an orphanage for elephants in Pinnawala Sri Lanka, which gives shelter to disabled, injured elephants. This program plays a large role in protecting the Sri Lankan Elephant from extinction.

Another subspecies, the Indian Elephant (Elephas maximus indicus) makes up the bulk of the Asian elephant population. Numbering approximately 36,000, these elephants are lighter gray in colour, with depigmentation only on the ears and trunk. Large males will ordinarily weigh only about 5,000 kgs (11,000 lb) but are as tall as the Sri Lankan. The mainland Asian can be found in 11 Asian countries, from India to Indonesia. They prefer forested areas and transitional zones, between forests and grasslands, where greater food variety is available.

The smallest of all the elephants is the Sumatran Elephant (Elephas maximus sumatranus). Population estimates for this group range from 2,100 to 3,000 individuals. It is very light gray and has less depigmentation than the other Asians, with pink spots only on the ears. Mature Sumatrans will usually only measure 1.7-2.6m at the shoulder and weigh less than 3,000 kg (6,600 lb). An enormous animal nonetheless, it is considerably smaller than its other Asian (and African) cousins and exists only on the island of Sumatra, usually in forested regions and partially wooded habitats.

In 2003 a further subspecies was identified on Borneo. Named the Borneo pygmy elephant, it is smaller and tamer than other Asian elephants. It also has relatively larger ears, longer tail and straighter tusks.
