Elephas
''Elephas'' is one of two surviving genera in the family of elephants, Elephantidae, with one surviving species, the Asian elephant, ''Elephas maximus''. Several extinct species have been identified as belonging to the genus, extending back to the Pliocene era. While formerly assigned to this genus, ''Elephas recki'', the straight-tusked elephant ''E. antiquus'' and the dwarf elephants '' E. falconeri'' and '' E. cypriotes'' are now placed in the separate genus ''Palaeoloxodon''. The genus is very closely related to the genus '' Mammuthus''. Taxonomy The scientific name ''Elephas'' was proposed by Carl Linnaeus in 1758 who described the genus and an elephant from Ceylon. The genus is assigned to the proboscidean family Elephantidae and is made up of one living and seven extinct species:Maglio, V.J. (1973). "Origin and evolution of the Elephantidae".

Asian Elephant
The Asian elephant (''Elephas maximus''), also known as the Asiatic elephant, is the only living species of the genus ''Elephas'' and is distributed throughout the Indian subcontinent and Southeast Asia, from India in the west, Nepal in the north, Sumatra in the south, and to Borneo in the east. Three subspecies are recognised—'' E. m. maximus'' from Sri Lanka, ''E. m. indicus'' from mainland Asia and '' E. m. sumatranus'' from the island of Sumatra. Formerly, there was also the Syrian elephant or Western Asiatic elephant (''Elephas maximus asurus'') which was the westernmost population of the Asian elephant (''Elephas maximus''). This subspecies became extinct in ancient times. Skeletal remains of ''E. m. asurus'' have been recorded from the Middle East: Iran, Iraq, Syria, and Turkey from periods dating between at least 1800 BC and likely 700 BC. It is one of only three living species of elephants or elephantids anywhere in the world, the others being the African bus ...

Elephas Maximus
''Elephas'' is one of two surviving genera in the family of elephants, Elephantidae, with one surviving species, the Asian elephant, ''Elephas maximus''. Several extinct species have been identified as belonging to the genus, extending back to the Pliocene era. While formerly assigned to this genus, '' Elephas recki'', the straight-tusked elephant ''E. antiquus'' and the dwarf elephants '' E. falconeri'' and '' E. cypriotes'' are now placed in the separate genus '' Palaeoloxodon''. The genus is very closely related to the genus ''Mammuthus''. Taxonomy The scientific name ''Elephas'' was proposed by Carl Linnaeus in 1758 who described the genus and an elephant from Ceylon. The genus is assigned to the proboscidean family Elephantidae and is made up of one living and seven extinct species:Maglio, V.J. (1973). "Origin and evolution of the Elephantidae".

Elephant
Elephants are the largest existing land animals. Three living species are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. They are the only surviving members of the family Elephantidae and the order Proboscidea. The order was formerly much more diverse during the Pleistocene, but most species became extinct during the Late Pleistocene epoch. Distinctive features of elephants include a long proboscis called a trunk, tusks, large ear flaps, pillar-like legs, and tough but sensitive skin. The trunk is used for breathing, bringing food and water to the mouth, and grasping objects. Tusks, which are derived from the incisor teeth, serve both as weapons and as tools for moving objects and digging. The large ear flaps assist in maintaining a constant body temperature as well as in communication. African elephants have larger ears and concave backs, whereas Asian elephants have smaller ears, and convex or level backs. Elepha ...

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] |
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, ...

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 conve ...

Straight-tusked Elephant
The straight-tusked elephant (''Palaeoloxodon antiquus'') is an extinct species of elephant that inhabited Europe and Western Asia during the Middle and Late Pleistocene (781,000–30,000 years before present). Recovered individuals have reached up to in height, and an estimated in weight. The straight-tusked elephant probably lived in small herds, flourishing in interglacial periods, when its range would extend as far north as Great Britain. Isolated tusks are often found while partial or whole skeletons are rare, and there is evidence of predation by early humans. It is the ancestral species of most dwarf elephants that inhabited islands in the Mediterranean. Description ''Palaeoloxodon antiquus'' was quite large, with individuals reaching in height. Like other members of '' Palaeoloxodon'', ''P. antiquus'' possesses a well developed parieto-occipital crest at the top of the cranium that anchored the splenius as well as possibly the rhomboid muscles to support the ...

Elephantidae
Elephantidae is a family of large, herbivorous proboscidean mammals collectively called elephants and mammoths. These are terrestrial large mammals with a snout modified into a trunk and teeth modified into tusks. Most genera and species in the family are extinct. Only two genera, '' Loxodonta'' (African elephants) and ''Elephas'' (Asiatic elephants), are living. The family was first described by John Edward Gray in 1821, and later assigned to taxonomic ranks within the order Proboscidea. Elephantidae has been revised by various authors to include or exclude other extinct proboscidean genera. Classification Scientific classification of Elephantidae taxa embraces an extensive record of fossil specimens, over millions of years, some of which existed until the end of the last ice age. Some species were extirpated more recently. The discovery of new specimens and proposed cladistics have resulted in systematic revisions of the family and related proboscideans. Elephantids are ...

Syrian Elephant
The Syrian elephant or Western Asiatic elephant (''Elephas maximus asurus'') was the westernmost population of the Asian elephant (''Elephas maximus''), which became extinct in ancient times. Skeletal remains of ''E. m. asurus'' have been recorded from the Middle East: Iran, Iraq, Syria, and Turkey from periods dating between at least 1800 BC and likely 700 BC. Due to the lack of any Late Pleistocene or early to mid Holocene record for Asian elephants in the region, there are suggestions that the elephants were anthropogenically introduced into the region during the Bronze Age, though this is disputed. Ancient Syrian craftsmen used the tusks of ''E. m. asurus'' to make ivory carvings. In Syria, the production of ivory items was at its maximum during the first millennium BC, when the Arameans made splendid ivory inlay for furniture. Description Syrian elephants were among the largest Asian elephant subspecies to have survived into historic times, measuring or more at ...

Dwarf Elephant
Dwarf elephants are prehistoric members of the order Proboscidea which, through the process of allopatric speciation on islands, evolved much smaller body sizes (around ) in comparison with their immediate ancestors. Dwarf elephants are an example of insular dwarfism, the phenomenon whereby large terrestrial vertebrates (usually mammals) that colonize islands evolve dwarf forms, a phenomenon attributed to adaptation to resource-poor environments and selection for early maturation and reproduction. Some modern populations of Asian elephants have also undergone size reduction on islands to a lesser degree, resulting in populations of pygmy elephants. Fossil remains of dwarf elephants have been found on the Mediterranean islands of Cyprus, Malta (at Għar Dalam), Crete (in Chania at Vamos, Stylos and in a now-underwater cave on the coast), Sicily, Sardinia, the Cyclades Islands and the Dodecanese Islands. Other islands where dwarf ''Stegodon'' have been found are Sulawesi, Flores, T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palaeoloxodon
''Palaeoloxodon'' is an extinct genus of elephant. The genus originated in Africa during the Pliocene era, and expanded into Eurasia during the Pleistocene era. The genus contains some of the largest known species of elephants, over four metres tall at the shoulders, including the European straight-tusked elephant (''Palaeoloxodon antiquus''), and the southern Asian '' Palaeoloxodon namadicus'', the latter of which was possibly the largest known land mammal based on fragmentary remains, but this requires proper reexamination. In contrast, the genus also contains many species of dwarf elephants that evolved via insular dwarfism on islands in the Mediterranean, some only a metre in height, making them the smallest elephants known. The genus has a long and complex taxonomic history, and at various times, it has been considered to belong to '' Loxodonta'' or '' Elephas'', but today is usually considered a valid and separate genus in its own right. Taxonomy In 1924, circumscribed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
