Su piel arrugada es móvil y contiene muchos centros nerviosos. Tiene las orejas más grandes, una cola más larga, y los colmillos más rectos que el elefante típico. Based on DNA analyses, E. m. maximus and E. m. indicus may be part of the same group, while the population of Elephas maximus in Borneo may be a distinct subspecies. Las crías son vulnerables a los ataques de los leopardos y especialmente de los tigres, por lo que los integrantes de la manada cooperan para no perder de vista a los más pequeños. Gray, T., C. Phan.

El elefante asiático ( Elephas maximus), también conocido como elefante asiático, es la única especie viva del género Elephas y se distribuye por el subcontinente indio y el sudeste asiático, desde India al oeste, Nepal al norte, Sumatra al sur. Iteroparous animals must, by definition, survive over multiple seasons (or periodic condition changes). Females suckle their calves frequently until about 2 years of age and continue suckling less frequently until 4 years of age. There is a positive correlation between the frequency of ear flapping and the temperature of the environment. Accessed The trunk is important in these types of communication. Also, males may not be as fit as females, because of the higher metabolic costs associated with musth. (Daniel, 1998; Kurt and Garai, 2007; Sukumar, 2003), Asian elephants are herbivores that eat many types of plant food. This works because the large surface area of the ears allows heat to be lost quickly. Choudhury, A., Lahiri Choudhury, D.K., Desai, A., Duckworth, J.W., Easa, P.S., Johnsingh, A.J.T., Fernando, P., Hedges, S., Gunawardena, M., Kurt, F., Karanth, U., Lister, A., Menon, V., Riddle, H., Rübel, A.

Elephas maximus also has a mutualistic relationship with the microbes in their digestive system. The longest known lifespan in the wild is not known because of the difficulty of estimating the age of adult elephants. , y a Borneo en el este. In adults, this hair is sparse, while calves have thicker brown hair. See also Tropical savanna and grassland biome. (Sukumar, 2006; Daniel, 1998; Gray and Phan, 2011; Sukumar, 2006), The Asian elephant has several behaviors related to thermoregulation. Las diferencias entre ambas especies son abundantes: para empezar, los elefantes asiáticos son más pequeños, con 2,0-3,5 metros de altura frente a los 2,7-4,0 metros que alcanzan los elefantes africanos (desde los elefantes asiáticos de Borneo hasta los de Sri Lanka por parte de los asiáticos, y desde los elefantes de la selva hasta los de la sabana por parte de los africanos), de cabeza abombada, orejas más pequeñas y redondeadas que no cubren los hombros, espalda arqueada y cola proporcionalmente más larga, aunque también coronada por un penacho de pelos negros, los únicos de longitud considerable en su piel dura, gruesa y correosa. No todos los ejemplares machos poseen colmillos, lo que se cree que es reflejo de la intensa caza que sufrieron por su marfil varios años atrás. There is increased chemical signaling and olfactory marking. Asian elephants flap their ear to get rid of excess heat. Historically, Elephas maximus had a geographic range of 9 million square kilometers across a large part of Asia. Ecotourism implies that there are existing programs that profit from the appreciation of natural areas or animals. They are also located near the center of the group to protect them from predators. Es el mayor mamífero del continente asiático. Sukumar, R. 2006. Está considerado como una especie en peligro de extinción. It is expected that the longest lifespan in the wild is similar to the longest lifespan in captivity. After males reach sexual maturity they leave the group to live solitary or in small groups with other males with loose social bonds. Esta especie es más pequeña que los elefantes africanos, ya que el asiático alcanza algo más de 3 metros de altura. The current geographic range is 500,000 square kilometers, which is only about 5% of the historical range. The Animal Diversity Web team is excited to announce ADW Pocket Guides! Convergent in birds.

The population is still currently decreasing, but these actions have slowed the decline in the population. When they are in trouble, a juvenile will make a distress call and the mother and other female elephants will respond quickly. humans benefit economically by promoting tourism that focuses on the appreciation of natural areas or animals. (Sukumar, 2003; Sukumar, 2006), Asian elephants are mutualists with some types of seed plants. The ADW Team gratefully acknowledges their support. During the hottest hours of the day, they are less active and spend time in shady areas. Su distribución original se extendía desde el sur de China e Indonesia occidental hasta las costas del golfo Pérsico y el sur de Mesopotamia , donde desapareció ya en el Neolítico .

This range extended as far west as current day Iraq, as far north as the Yangtze River in China, and across the Indian subcontinent and Southeast Asia, including the islands of Sri Lanka and Sumatra (Indonesia). Uno de los aspectos más intrigantes de los elefantes asiáticos es un estado que se abate en ocasiones sobre los machos de esta especie, conocido en la India como musth. generally wanders from place to place, usually within a well-defined range. Since only males have tusks, poaching leads to extremely skewed sex ratios, creating a problem with inbreeding since there aren't enough breeding males.

The subspecies Elephas maximus sumatranus is Critically Endangered. The female is required to cooperate for breeding to occur, so they will only allow the strongest and most fit males to mate with them. The elephant can make many types of vocalizations that can travel both long and short distances. For example: antlers, elongated tails, special spurs. Elephas maximus maximus is different from the other subspecies because 90 to 95 percent of males lack tusks.
