[citation needed] The enamel plates of the molars are greater in number and closer together in Asian elephants. Elephant behavior adaptation. Copyright 2021 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. Of 349 captive calves born, 142 died prematurely. They have been used particularly for timber-carrying in jungle areas. Although they belong to same order and family, they are different from each other in terms of their body shape, size, behaviour etc. The acute sense of smell uses both the trunk and Jacobson's organ. Part of the reason this adaptation is so important is because Asian elephant eyes are relatively small, and their eyesight relatively poor. [13][14] The Asian elephants living in northern Borneo are smaller than all the other subspecies, but with larger ears, a longer tail, and straight tusks. Range. In China, the Asian elephant survives only in the prefectures of Xishuangbanna, Simao, and Lincang of southern Yunnan. "Elephants and humans have many similar characteristics in their life history and behaviour. One … These are related to lack of exercise, long hours standing on hard substrates, and contamination resulting from standing in their dung. Their trunk is the main thing they use to find things and eat stuff. Results of phylogeographic and morphological analyses indicate that the Sri Lankan and Indian elephants are not distinct enough to warrant classification as separate subspecies. Aside from these 10 physical differences, there is a big difference between African and Asian elephants in range and diet: 11. [4] Since 1986, the Asian elephant has been listed as Endangered on the IUCN Red List, as the population has declined by at least 50 percent over the last three elephant generations, which is about 60–75 years. Adult females and calves move about together as groups, while adult males disperse from their mothers upon reaching adolescence. The genetic divergence of Borneo elephants warrants their recognition as a separate Evolutionarily Significant Unit.[36]. Asian elephants are poached for ivory and a variety of other products including meat and leather. This view is adapted wholesale from the many excellent long-term studies of African savannah elephants [1-3], … Although the amount of ivory being openly sold has decreased substantially since 2001, Thailand still has one of the largest and most active black markets for ivory seen anywhere in the world. They can sometimes be known for their violent behavior. One way they cool down is by flapping their ears to fan themselves. DESCRIPTION: The largest land mammal in India, the Asian Elephant’s grey wrinkled skin, long trunk and sail-like ears make it one of the most easily recognized animals. [11] These three subspecies are currently recognised as valid taxa. E. m. maximus In 2020, the population of Asian elephants in Yunnan was estimated at around 300 individuals. Rangarajan, M., Desai, A., Sukumar, R., Easa, P. S., Menon, V., Vincent, S., Ganguly, S., Talukdar, B. K., Singh, B., Mudappa, D., Chowdhary, S., Prasad, A. N. (2010). E. m. sumatranus Elephant Voices: How Elephants Communicate, UW LaCrosse: How Elephants Adapt to Their Surroundings. An elephant’s trunk has more than 40,000 muscles, more than all the muscles in a human body! They can be very emotional at times including the birth of new babies and at the death of others. Asian elephants are herbivores and spend about three-quarters of each day eating or moving toward a food or water source. [31][32], Asian elephants inhabit grasslands, tropical evergreen forests, semi-evergreen forests, moist deciduous forests, dry deciduous forests and dry thorn forests, in addition to cultivated and secondary forests and scrublands. [19][20][21] Sexual dimorphism in body size is relatively less pronounced in Asian elephants than in African bush elephants; with males averaging 15% and 23% taller in the former and latter respectively. Representations of human-elephant conflict in Indian and international media", "Impact of border fence along India – Bangladesh border on elephant movement", "Elephant conservation in India – an overview", "The status of ivory trade in Thailand and Vietnam", Skinned; The growing appetite for Asian elephants, "Tourism driving illegal elephant trade in Burma and Thailand – video", "Activists Denounce Thailand's Elephant "Crushing" Ritual", "Identifying appropriate flagship species: The importance of culture and local contexts", "Mutiny or Clear Sailing? This is especially true of males in musth and of females with young. [4] They need 80–200 litres of water a day and use even more for bathing. Six Asian elephants at the Oregon Zoo were observed to determine the effects of a poured rubber flooring substrate on captive Asian elephant behavior. [9] [1], The Asian elephant is the largest living land animal in Asia. [88], Elephants have been captured from the wild and tamed for use by humans. [4], Generation length of the Asian elephant is 22 years. [34], The Borneo elephant occurs in Borneo's northeastern parts, primarily in Sabah (Malaysia), and sometimes in Kalimantan (Indonesia). They browse more in the dry season with bark constituting a major part of their diet in the cool part of that season. [65][66] As a whole, Asian elephants display highly sophisticated and sometimes unpredictable behaviour. Asian elephants adaptations to their environments include developing cooling mechanisms like big ears growing up to six sets of new teeth to support their herbivorous diet and learning ways to communicate using low frequency vibrations to compensate for their small eyes and poor eyesight. That communication is especially important when it comes to protecting one another. [7] A herd of 20–25 wild elephants was reported as being present in the Garo Hills of Mymensingh in the late-1990s, being detached from a big herd in the Peack hills of India and prevented from returning by fences put up in the meantime by the Indian border security force. [4] The largest bull elephant ever recorded was shot by the Maharajah of Susang in the Garo Hills of Assam, India in 1924, it weighed an estimated 7 t (7.7 short tons), stood 3.43 m (11.3 ft) tall at the shoulder and was 8.06 m (26.4 ft) long from head to tail. [46] They can use infrasound to communicate. [4][3] Elephants that have been abused by humans in the past often become "rogue elephants", which regularly attack people with no provocation. Elephants are known to be right or left tusked. During the heat of the day they will rest. [52], Asiatic elephants reach adulthood at 17 years of age in both sexes. In India alone, over 400 people are killed by elephants every year, and 0.8 to 1 million hectares are damaged, affecting at least 500,000 families across the country. Asian Elephants can be found in Sri Lanka, Laos, Thailand, Burma, China, Malaysia, India, Indonesia and Cambodia. In Bangladesh, some isolated populations survive in the south-east Chittagong Hills. [4], Asian elephants have a very large and highly developed neocortex, a trait also shared by humans, apes and certain dolphin species. Asian Elephants have a really good sense of hearing and smell. Gunfire and other similar methods of deterring, which are known to be effective against many kinds of wild animals including tigers, may or may not work with elephants, and can even worsen the situation. Many of the problems are treatable. In zoos, Asian elephants die at a much younger age; captive populations are declining due to a low birth and high death rate. The elephant plays an important part in the culture of the subcontinent and beyond, being featured prominently in the Panchatantra fables and the Buddhist Jataka tales. Results of studies indicate that Asian elephants have cognitive abilities for tool use and tool-making similar to great apes. [53] Average elephant life expectancy is 60 years in the wild and 80 in captivity, although this has been exaggerated in the past. Cow-calf units generally tend to be small, typically consisting of three adults (most likely related females) and their offspring. Finally, you can look at the tusks. They are known to feed on at least 112 different plant species, most commonly of the order Malvales, as well as the legume, palm, sedge and true grassfamilies. It is now recognized that females form extensive and very fluid social networks, with varying degrees of associations between individuals. [19] Length of body and head including trunk is 5.5–6.5 m (18–21 ft) with the tail being 1.2–1.5 m (3.9–4.9 ft) long. They do sometimes form ‘bachelor herds’, however, and it’s common for a group of male calves to all leave their herd and mothers simultaneously and live together for a while before dispersing once they’re fully grown. Body temperature averages 35.9 °C (96.6 °F). [24], The trunk can hold about four litres of water. It is primarily threatened by loss of habitat, habitat degradation, fragmentation and poaching. [39] They are generalist feeders, and are both grazers and browsers. The elephant is a herbivorous animal. [17], The distinctive trunk is an elongation of the nose and upper lip combined; the nostrils are at its tip, which has a one finger-like process. One of the major instigators of human–wildlife conflict in general is competition for space. Another risk factor is being born into a zoo rather than being imported from the wild, with poor adult survivorship in zoo-born Asians apparently being conferred prenatally or in early infancy. In 2010, four skinned elephants were found in a forest in Myanmar; 26 elephants were killed by poachers in 2013 and 61 in 2016. Their ears are like built in cooling systems. In contrast, Asian elephant teeth have a compressed diamond-shaped tooth profile. [2] The earliest indications of captive use of Asian elephants are engravings on seals of the Indus Valley Civilisation dated to the 3rd millennium BC. Asian elephants have adapted to be able to use a series of vibrations to communicate with each other. Examining the Role of the Asian Elephant as a Flagship Species", "OKC Zoo to host 2nd annual Asian Elephant Awareness Month", "It's risky, but elephants are feeling frisky", Proposed Eastern Extension to Salakpra Wildlife Sanctuary, "Assam students, environment activists launch online campaign to stop coal mining in elephant reserve", "Compromised Survivorship in Zoo Elephants", 10.1002/1098-2361(2000)19:5<299::AID-ZOO2>3.0.CO;2-Z, "Skewed Birth Sex Ratio and Premature Mortality in Elephants", "The Forest and the Field in Ancient India", "War elephants still exist. In addition, only male Asian elephants have tusks while both African elephant sexes have them². Tusks from Thai poached elephants also enter the market; between 1992 and 1997 at least 24 male elephants were killed for their tusks. [80] In recent years the National Park has faced issues due to encroachment and over-exploitation. Female calves remain with the herd they were born in. Williamson, J.H. Asian Elephant and African Elephant. Depredation in human settlements is another major area of human–elephant conflict occurring in small forest pockets, encroachments into elephant habitat, and on elephant migration routes. [4], Female Asian elephants usually lack tusks; if tusks—in that case called "tushes"—are present, they are barely visible, and only seen when the mouth is open. [67][68][69], The demand for ivory during the 1970s and 1980s, particularly in East Asia, led to rampant poaching and the serious decline of elephants in both Africa and Asia. Male elephants usually live alone, meeting up with herds when it is time to mate and then wandering off again shortly afterwards. [57] [12], Elephas maximus borneensis was proposed by Paules Edward Pieris Deraniyagala in 1950 who described an elephant in an illustration published in the National Geographic magazine, but not a living elephant in accordance with the rules of the International Code of Zoological Nomenclature. (2010). Strong fights over access to females are extremely rare. [4] They are classified as megaherbivores and consume up to 150 kg (330 lb) of plant matter per day. Female Asian elephants live in a herd led by a dominant female (the matriarch). Once a female gives birth, she usually does not breed again until the first calf is weaned, resulting in a four to five-year birth interval. Breaking down those fibrous plants can be tough on teeth, and just like humans, it’s common for those teeth to start to wear down. In the Burmese, Thai and Sinhalese animal and planetary zodiac, the elephant, both tusked and tuskless, are the fourth and fifth animal zodiacs of the Burmese, the fourth animal zodiac of the Thai, and the second animal zodiac of the Sinhalese people of Sri Lanka. These differences in physical appearance were known for quite some time but it … (1950). [81], In India, the National Board of Wildlife did a recommendation, allowing coal mining in the Dehing Patkai elephant reserve in April 2020. [44], Unlike African elephants, which rarely use their forefeet for anything other than digging or scraping soil, Asian elephants are more agile at using their feet in conjunction with the trunk for manipulating objects. Behavior. [47], Rarely, tigers have been recorded attacking and killing calves, especially if the calves become separated from their mothers, stranded from their herd, or orphaned. Populations inhabiting small habitat fragments are much more liable to come into conflict with humans. Thirgood, S., Woodroffe, R., & Rabinowitz, A. There is a singular anecdotal case of a mother Asian elephant allegedly being killed alongside her calf; however, this account is contestable. The cold water can cool them down, and the dirt or mud can work as a layer to protect their skin from sunburn. Diet. [18], Elephants are able to distinguish low-amplitude sounds. Recent research however has shown this is not actually … They are known to feed on at least 112 different plant species, most commonly of the order Malvales, as well as the legume, palm, sedge and true grass families. To help protect the skin from parasites and biting insects, elephants wallow in mud or spray dust on their wet skin. [4], The "proboscis" or trunk consists wholly of muscular and membranous tissue, and is a tapering muscular structure of nearly circular cross-section extending proximally from attachment at the anterior nasal orifice, and ending distally in a tip or finger. Yunnan province has 11 national and regional nature reserves. Elephants eat roots, grasses, leaves, bark, bananas and sugar cane. Santiapillai, C., Wijeyamohan, S., Bandara, G., Athurupana, R., Dissanayake, N., & Read, B. Explore Behavior and Ecology. At times, they scrape the soil for clay or minerals. Amazingly, though, all kinds of elephants have developed behavioral adaptations over time that help them survive even in hostile environments. Asian elephants form herds of about 20 females. [75][76][59], The World Elephant Day is celebrated on 12 August since 2012. Its folds increase surface area for heat dissipation. The epidermis and dermis of the body average 18 mm (0.71 in) thick; skin on the dorsum is 30 mm (1.2 in) thick providing protection against bites, bumps, and adverse weather. African and Asian elephants both belong to the order Proboscidea and family elephantidae. Thus, they have adapted their other senses to compensate. It has up to 20 pairs of ribs and 34 caudal vertebrae. It is smoother than that of African elephants, and may be depigmented on the trunk, ears, or neck. [70], Up to the early 1990s, Vietnamese ivory craftsmen used exclusively Asian elephant ivory from Vietnam and neighbouring Lao and Cambodia. ASIAN ELEPHANT/Behaviour, Distribution, Habitat, Size, Weight, IUCN stetus ASIAN ELEPHANT. [8] This behaviour is very complex, and few species are known to be able to attribute and consider another’s feelings in this way (Byrne et al., 2008). The animals sometimes get as many as six sets of teeth throughout their lifetime, with new, fresh ones growing in as older, tired teeth fall out. Asian elephants have also adapted when it comes to teeth. It is proposed that the major differences between the two species in terms of population structure, social groupings, and habitat utilization reflect the longer history of the Asian elephant's adaptation to a forest-grassland ecotone. [41] They drink at least once a day and are never far from a permanent source of fresh water. The lip of the … Calf Adult. It would be a stretch to say elephants, or any other animals, understand … [82], About half of the global zoo elephant population is kept in European zoos, where they have about half the median life span of conspecifics in protected populations in range countries. The emotions of elephants are very important as well. m. maximus from Sri Lanka, E. m. indicus from mainland Asia and E. m. sumatranus from the island of Sumatra. African elephants have huge complicated social groups ranging from tens to hundreds, whereas Asian elephants are often thought to be the loner elephants. Since the typical Asian elephant habitat is in hot climates in places like Southeast Asia and India, they must find ways to cool themselves and protect their bodies from the sun. The animals are mostly herbivores, and they spend a lot of time chomping down on foods like grass, bark and roots. Both male and female African elephants can have tusks, but only male Asian elephants can grow them. Their diet consists of bark and leaves of both trees and … Raihan Sarker, A. H. M., & Røskaft, E. (2010). The communicative vibrations the elephants share are at too low of a frequency for humans or other potential predators to hear, but the elephants have learned to be able to talk to each other using vibrations. Let us see how an African elephant differs from an Asian elephant. The decision raised concerns between students and environmental activists who launched an online campaign to stop the project. Three subspecies are recognised—E. Resources like food and water aren’t always easy to find in the hot environments where elephants live, especially as human degradation threatens the Asian elephant habitat. The trunks are used like a hose to spray water across the body. The adaptation helps keep the large animals healthy and fed throughout their lifetime. Between the age of 10 and 20 years, bulls undergo an annual phenomenon known as "musth". Elephants use their trunks for breathing, watering, feeding, touching, dusting, sound production and communication, washing, pinching, grasping, defence and offence. The practice has been aided by China's State Forestry Administration (SFA), which has issued licences for the manufacture and sale of pharmaceutical products containing elephant skin, thereby making trading legal. [25], Tusks serve to dig for water, salt, and rocks, to debark and uproot trees, as levers for maneuvering fallen trees and branches, for work, for display, for marking trees, as weapon for offence and defence, as trunk-rests, and as protection for the trunk. However, mistreatment may lead to serious disability or death. Economic liberalisation and an increase in tourism raised both local and visitors' demands for worked ivory, which resulted in heavy poaching. Phase I (Baseline Phase) examined elephant behavior on old concrete floors. Asian elephant walking in Tad Lo river, Salavan Province. They are classified as megaherbivores and consume up to 150 kg (330 lb) of plant matter per day. An Asian elephant has 5 toes on the front of the feet and and 4 on the back. II. In the eastern Himalaya in northeast India, they regularly move up above 3,000 m (9,800 ft) in summer at a few sites.[33].
