Proboscidean
The Proboscidea (; , ) are a taxonomic order of afrotherian mammals containing one living family (Elephantidae) and several extinct families. First described by J. Illiger in 1811, it encompasses the elephants and their close relatives. From the mid-Miocene onwards, most proboscideans were very large. The largest land mammal of all time may have been a proboscidean; '' Palaeoloxodon namadicus'' was up to at the shoulder and may have weighed up to , almost double the weight of some sauropods like '' Diplodocus carnegii''. The largest extant proboscidean is the African bush elephant, with a record of size of at the shoulder and . In addition to their enormous size, later proboscideans are distinguished by tusks and long, muscular trunks, which were less developed or absent in early proboscideans. Three species of elephant are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. Elephantidae is the only surviving family of t ...

Indian Elephant
The Indian elephant (''Elephas maximus indicus'') is one of four extant recognised subspecies of the Asian elephant and native to mainland Asia. Since 1986, the Asian elephant has been listed as Endangered on the IUCN Red List as the wild population has declined by at least 50% since the 1930s to 1940s, i.e. three elephant generations. The Asian elephant is threatened by habitat loss, degradation and fragmentation. Characteristics In general, Asian elephants are smaller than African elephants and have the highest body point on the head. The tip of their trunk has one finger-like process. Their back is convex or level. Indian elephants reach a shoulder height of between , weigh between , and have 19 pairs of ribs. Their skin colour is lighter than that of '' E. m. maximus'' with smaller patches of depigmentation, but darker than that of '' E. m. sumatranus''. Females are usually smaller than males, and have short or no tusks. The largest Indian elephant was high at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lists Of Mammals By Population
This is a collection of lists of mammal species by the estimated global population, divided by orders. Lists only exist for some orders; for example, the most diverse order - rodents - is missing. Much of the data in these lists were created by the International Union for Conservation of Nature (IUCN) Global Mammal Assessment Team, which consists of 1700 mammalogists from over 130 countries. They recognize 5488 species in the class. These lists are not comprehensive, as not all mammals have had their numbers estimated. For example, a live specimen of the spade-toothed whale was first observed in December 2010, and the event only recognized as such in November 2012; no estimate yet exists for the global population. The accuracy of the quote numbers may only be an order of magnitude. It is estimated that the total number of wild mammals in the world is about 130 billion.

Lists Of Organisms By Population
This is a collection of lists of organisms by their population. While most of the numbers are estimates, they have been made by the experts in their fields. Species population is a science falling under the purview of population ecology and biogeography. Individuals are counted by census, as carried out for the piping plover; using the transect method, as done for the mountain plover; and beginning in 2012 by satellite, with the emperor penguin being first subject counted in this manner. Number of species More than 99 percent of all species, amounting to over five billion species, that ever lived on Earth are estimated to be extinct. Estimates on the number of Earth's current species range from 10 million to 14 million, of which about 1.2 million have been documented and over 86 percent have not yet been described. According to another study, the number of described species has been estimated at 1,899,587. 2000–2009 saw approximately 17,000 species described per year. The total ...

Borneo Elephant
The Borneo elephant, also called the Bornean elephant or the Borneo pygmy elephant, is a subspecies of Asian elephant ''(Elephas maximus)'' that inhabits northeastern Borneo, in Indonesia and Malaysia. Its origin remains the subject of debate. A definitive subspecific classification as ''Elephas maximus borneensis'' awaits a detailed range-wide morphometric and genetic study. Since 1986, the Asian elephant has been listed as Endangered on the IUCN Red List as the population has declined by at least 50% over the last three generations, estimated to be 60–75 years. It is pre-eminently threatened by loss, degradation and fragmentation of habitat. The Sultan of Sulu was thought to have introduced captive elephants to Borneo in the 18th century, which were released into the jungle. Comparison of the Borneo elephant population to putative source populations in DNA analysis indicates that the Borneo elephants more likely derived from Sundaic stock and are indigenous to Borneo, ...

Sumatran Elephant
The Sumatran elephant (''Elephas maximus sumatranus'') is one of four recognized subspecies of the Asian elephant, and native to the Indonesian island of Sumatra. In 2011, IUCN upgraded the conservation status of the Sumatran elephant from endangered to critically endangered in its Red List as the population had declined by at least 80% during the past three generations, estimated to be about 75 years. The subspecies is preeminently threatened by habitat loss, degradation and fragmentation, and poaching; over 69% of potential elephant habitat has been lost within the last 25 years. Much of the remaining forest cover is in blocks smaller than , which are too small to contain viable elephant populations. Characteristics In general, Asian elephants are smaller than African elephants and have the highest body point on the head. The tip of their trunk has one finger-like process. Their back is convex or level. Females are usually smaller than males, and have short or no tusks. Su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sri Lankan Elephant
The Sri Lankan elephant (''Elephas maximus maximus'') is native to Sri Lanka and one of three recognised subspecies of the Asian elephant. It is the type subspecies of the Asian elephant and was first described by Carl Linnaeus under the binomial ''Elephas maximus'' in 1758. The Sri Lankan elephant population is now largely restricted to the dry zone in the north, east and southeast of Sri Lanka. Elephants are present in Udawalawe National Park, Yala National Park, Lunugamvehera National Park, Wilpattu National Park and Minneriya National Park but also live outside protected areas. It is estimated that Sri Lanka has the highest density of elephants in Asia. Human-elephant conflict is increasing due to conversion of elephant habitat to settlements and permanent cultivation. Characteristics In general, Asian elephants are smaller than African elephants and have the highest body point on the head. The tip of their trunk has one finger-like process. Their back is convex or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
