Elephant sexual maturety-ADW: Elephas maximus: INFORMATION

Elephants are slow-growing, long-lived mammals, surviving up to 70 years in the wild. The length of an individual's life, or its longevity, and reproductive success go hand in hand. Older females are more successful at raising their offspring to maturity than are younger females, and the oldest males are the primary breeders. These older and more experienced individuals are often targets of ivory poachers and sport hunters because of their generally larger tusks, but their removal can have serious consequences. Elephants rely on older members for their social and ecological knowledge and leadership abilities, and entire families and even populations may be damaged by the removal of a few key individuals.

Younger mothers are less experienced in calf care, and they are themselves xexual growing. From then on young males steadily spend more time away from the family gradually moving towards Elephant sexual maturety.

  • The Age of Sexual Maturity in Rabbits Due to the great variations between rabbit breeds including variations in size and weight at adulthood , there are also variations between the times at which certain breeds reach sexual maturity.

Elephants live in small family groups led by old females cows. Where food is plentiful, the groups join together. Most males bulls live in bachelor herds apart from the cows.

Males and females both possess two glands that open between the eye and ear. Elephants of all ages and sexes secrete a fluid called temporin out of this orifice.

Musth is the time for establishing reproductive hierarchy , which can differ from the usual social hierarchy in that a male in musth outranks nonmusth males. In the wild, males are usually at their prime physical state during musth and ordinarily do most of the breeding.

Elephants are able to assess the reproductive status of one another by using their keen sense of smell. Inside the skull , elephants possess from seven to nine nasal turbinal s with specialized sensitive tissues for olfaction.

Humans have only three turbinals; dogs have five. When a female is in estrus , or when a male is in musth, an elephant apparently can detect airborne hormones. This organ conveys the molecules to the brain for analysis. Hormones are also sniffed directly from urine and feces.

Gestation is the longest of any mammal 18—22 months. The newborn elephant is about a metre 3. It suckles by using the mouth, not the trunk, at mammary glands located in the chest region. After weaning, many hours of each day are spent eating. Elephants reach sexual maturity early in their second decade of life.

African elephants become sexually mature at age 10—12, whereas Asian elephants become sexually mature about age It is during that period that males leave their natal herd herd of origin to live either singly or in small herds with other males. Females, in contrast, remain with their natal herd for their whole lives. Despite living apart, adult male and female elephants form short-lived mating or feeding associations with one another.

Elephants can live to 80 years of age or more in captivity but live to only about 60 in the wild. Elephants migrate seasonally according to the availability of food and water. Memory plays an important role during this time, as they remember locations of water supplies along migration routes. Intelligence has also been observed in conjunction with memory. One elephant, using its tusks and trunk, stripped bark from a nearby tree and chewed it until it made a large ball, then plugged a waterhole it had previously dug and covered the plug with sand.

Subsequently, the elephant was seen to uncover the sand, unplug the hole, and drink—a behaviour that could be interpreted as tool-making. One study of captive Asian elephants suggested that they are capable of recognizing themselves in a mirror, a trait shared by only a few other nonhuman animal species.

Although unable to jump or gallop, elephants can reach a top speed of 40 km 25 miles per hour. Their feet are well adapted to carrying their great weight. The heel is partially elevated, and below it is a thick fatty, fibrous wedge of tissue protected by thick skin. It is not easy for elephants to lie down and get up; they sleep lying down for three to four hours during the night.

While standing, elephants doze for short periods but do not sleep deeply. An adult elephant consumes about kg of food and litres 26 gallons of water per day; these amounts can double for a hungry and thirsty individual. Such consumption makes elephants an important ecological factor; they substantially affect and even alter the ecosystems they live in. For many centuries the Asian elephant has been important as a ceremonial and draft animal.

Historical records of tamed Asian elephants date to the Indus civilization of the 3rd millennium bce. At Mohenjo-daro and Harappa , Pakistan, soapstone carvings depict elephants with cloth on their backs, which indicates use by humans. Mahouts and oozies elephant trainers in India and Myanmar, respectively are skilled people who remain in direct contact with the animals for many years. Hastividyarama , an age-old handbook for elephant tamers, spells out prescribed training procedures in detail and is still used today in some parts of Asia.

Commanded by its mahout, the elephant was once basic to Southeast Asian logging operations. It remains a symbol of power and pageantry but has been largely supplanted by machinery.

At the beginning of the 21st century, Thailand and Myanmar each had about 5, captive elephants employed in traditional roles intermingled with modern use as tourist attractions. The most famous historical event using elephants in war was that of Hannibal , the young commander of the Carthaginians who crossed the Alps from Spain into Italy. He left Cartagena, Spain, in bce with 37 elephants—36 African forest elephants and one Asian—each under its own well-trained mahout.

African elephants were also tamed during the19th century, in what was the Belgian Congo. Training of these forest elephants was initiated by King Leopold II of Belgium and was conducted by Indian mahouts with Asian elephants. African elephants are now used mainly for transporting tourists in Garamba National Park , where they are valuable in providing revenue to sustain its activities. At the beginning of the 21st century, fewer than 50, Asian elephants remained in the wild.

Threatened by habitat loss and poaching , Asian and African elephants are listed as endangered species. From to the number of African elephants in the wild was reduced by more than half, from 1,, to ,, partly a result of commercial demand for ivory. However, in some parts of Africa elephants are abundant, and culling is practiced in some reserves to prevent habitat destruction. A nine-year ban on the ivory trade was lifted in , and Botswana , Namibia , and Zimbabwe were allowed to sell limited stocks of ivory from government warehouses to Japan.

In South Africa joined the three southern African nations in selling limited amounts of ivory from existing stocks. Article Media. Info Print Print. Table Of Contents. Submit Feedback.

The tail is two-thirds white with a broad black band at the end. Each annual molt diminishes the white until at maturity about five years it disappears.

Eyes are a darker brown. Golden eagles are sometimes mistaken for an immature bald eagle. The feathered lower legs, slightly larger wingspan and smaller beak can distinguish them. Golden eagle behavior and facts Golden eagles prey on small mammals, birds, reptiles and jackrabbits, with mammals comprising more than 70 percent of their diet. They may also eat carrion. When game birds are abundant, eagles prey on them. They use their soaring ability and keen eyesight to locate prey.

After spotting it, they dive at speeds up to mph and seize the prey with their feet and talons. Most prey is taken on the ground, but large birds such as goose, crane or diving ducks may be struck in the air.

A pair of golden eagles occupies a territory size that depends on available prey. For instance, in Scotland they require 11, to 18, acres; in California, 19 to 59 square miles. In the Northeastern United States, the territory may be up to square miles, but only a small portion of that may provide suitable prey habitat. Populations from northern areas migrate south in winter; eagles from more temperate climates remain year round. Courtship displays and mating behaviors may be seen in almost any month.

Aerial displays are commonly seen between mated pairs, including undulating flights involving a complex series of dives and swoops. The pair may also soar together, and the male will dive toward the female who turns on her back and presents her talons to his. From birth to death Mating: year-round.

Nests are built on rocky cliffs or in tall trees. Eagles may reuse and enlarge their nest each year; nests on cliff ledges can be up to eight feet in diameter and three to four feet thick. Tree nests are usually deeper and more massive. The largest recorded nest: 17 feet deep and four feet across. One to four eggs — most commonly two — are laid in March at three- to four-day intervals.

Eggs are dull white with brown blotches. Incubation: five to six weeks, mostly by the female. Chicks hatch at intervals over several days. If food is scarce and there is more than one chick, competition between siblings can be fierce and typically only the oldest will survive.

For the first 14 days, both parents tend the chicks, although males are more likely to be hunting while the females guard the nest. During this time, the parents tear off and feed small bits of raw meat to the chicks.

How Do Elephants Mate? | Sciencing

The range of African elephants Loxodonta africana is patchily distributed across central and southern Africa in the Ethiopian Region. Remnant populations exist as far northwest as Guinea-Bissau and as far northeast as Ethiopia.

Disjunct populations exist southward into northern South Africa, and include contiguous populations in Gabon, Tanzania, Botswana, and Zambia. Once present in Burundi, Gambia, and Mauritania, they've now been extirpated from those countries.

These elephants were extirpated from Swaziland, as well, but have been re-introduced here in recent years. Blanc, ; Laursen and Bekoff, ; Thomas, et al.

African elephants are found in many habitats of Africa such as savannas, rain forests, woodlands, scrub forests, occasionally deserts, and beaches. However, due to poaching threats protected sanctuaries are their main habitats. Within these sanctuaries, these elephants will inhabit areas that have sources of water and abundant vegetation for foraging.

Across these habitats, the elevation level ranges from sea level 0 meters to meters. Duffy, et al. Currently, African elephants are the largest terrestrial organism. Female elephants can range from 2, to 3,kg in mass and stand 2. Male elephants are larger, ranging from 4, to 6,kg in mass and standing 3. Distinguishing characteristics between the sexes include head shape, width of forehead, saddle-back vs straight back, and tusk size.

Males are broader with a curvy build. Both sexes have two thick, ivory tusks which are curved and can reach up to cm in length. African elephants have muscular trunks that are able to grab objects and can be used for breathing purposes. They can grab objects due to the unique shape at the end of the trunk. Their sizable ears are triangular and can help keep them cool in the hot, summer months. African elephants have creased, gray skin covered with papillae. The thick up to 30 mm , immobile skin covers the majority of the body, while bumpy skin covers areas that require a lot of movement.

Smooth skin can be found on delicate areas of the body. Hair that varies in color, length, and thickness can be found along the body. Hair that grows along the back and tail is flattened dark hair that can grow to 0. Hair around the eyes is long in order to prevent foreign objects from entering the eyes. Calves have different hair coloring and texture. Their hair is softer with a lighter tone such as a red or brown.

At birth, calves do not have tusks but instead have temporary premaxillary incisors. These incisors are replaced at about a year of age with incisors that will ultimately form the tusks. Adult African elephants have lophodont dentition, with 6 molars that grow and move forward, like on a conveyor belt.

They are worn down, lost, and replaced throughout their lives. Once the sixth set of molars is worn down, there are no additional teeth to replace them and the elephant is not able to process forage. Laursen and Bekoff, ; Nowak, The estrus state is how bulls know if cows are ready to mate.

This is done by a scent in female urine and genital area. During the courtship process, bulls approach females and attempts to use their trunk to stroke her.

Bulls will put up a fight in order to mate, by chasing the females if they retreat. When females stop retreating, they will join the bulls in stroking each other with their trunks. The courtship continues by females surrendering their hindquarters to the males. Bulls then mount the females to begin mating. The males will thrust repeatedly into the females for up to 2 mins.

While females are in an estrus state, they may mate with several different bulls, and are considered polygynandrous. They are cooperative breeders, in which females have help raising young by other members of the family or "clan. African elephants are viviparous animals, meaning that they birth their young live. They breed year-round with no seasonal differences. The number of offspring is usually limited to one for each birthing period but in rare cases, twins may be born.

They breed once every years, and will give birth to an average of four calves in their lifetime. The gestation period is about 22 months but is strongly influenced by environmental factors. The gestation period may be shorter if the environmental factors are favorable for newborns survival. Newborn African elephants will weigh between kg, with kg being the average birth weight.

Offspring are completely dependent on their mother's milk until they are weaned at four months, but continue to occasionally drink their mother's milk for up to three years. Young African elephants will gain their full independence around eight years of age. Sexual maturity occurs at different ages for males and females. Males will reach sexual maturity around 20 years of age, while females will reach sexual maturity around 11 years of age.

Hildebrandt, et al. In African elephant herds, primarily the mother and other females assist in taking care of the young.

When female elephants give birth, they will move away from the herd in order to allow space for the offspring. When they return, all members of the herd will inspect the new elephant thoroughly. Until young elephants are around 4 years of age, they will closely follow their mother.

During this time, mothers will feed their young through breast milk and help them move around obstacles. Until young offspring are independent, around 8 years of age, they will depend on the rest of the herd to teach them how to use their trunks, forage for food, and move around tough obstacles. Maternal position only affects the young if the mother is the leader of the herd, in which case, the young will be the next leader of the herd.

Laursen and Bekoff, ; Miller and Andrews, African elephants reportedly have been known to live up to a maximum of 65 years in captivity. However, unpublished reports have stated that African elephants may live up to 80 years in captivity. In the wild, African elephants live for an average of years. African elephants generally are slow moving creatures. How much they travel each day depends on the amount of resources in close proximity that they require; the average walking distance for African elephants is around 10 km a day.

Before African elephant populations were constricted to large reservations for protection, they migrated hundreds of kilometers seasonally, from high to low altitudes and vice versa. African elephants are active animals for the majority of time in a hour period, due to the amount of food they must consume each day. They are dormant in the early morning hours with an additional sleep midday for a total of 4 hours of sleep every day.

During this time they scavenge for food and groom themselves. Grooming consist of African elephants using their trunks to cover themselves with mud or water, and the process helps them maintain hydration. Female African elephants are social animals that live in herds of 6 to 70 members. These herds have a matriarchal order, and consist of females cows and their young. The alpha elephant in these herds tends to be the biggest and most dominant.

Male African elephants bulls tend to only live within a herd if they are not old enough to go out on their own or for mating purposes. Bulls will live a life in solitary or with a few other bulls. Greco, et al. If enough essential resources are present African elephants will move as little as 1. When resources are scarce, African elephants may travel as much as 40 km a day. Thouless reported that African elephants' home range can vary from to km within a period of 25 months.

Miller, et al. African elephants communicate acoustically with others of their species. Many of their calls are low frequency calls of ca. They can make a variety of calls including rumble, trumpet, snort, roar, bark, and grunt. Soltis reports 3 other calls made by these elephants. They include "rev, croak, and chuff. A "soft chirp" shows submission or intimidation.

Infant elephants will gurgle during play and squeal when frightened. The African elephants can hear one of these calls from over 2km away. They will make these calls to warn or gather others in their herd or to signal they are ready to mate. African elephants watch and listen to their surrounding environment for signs of something amiss. They communicate visually by using their trunks or ears to signal other herd members. Tactile communication is between a mother and her child or two elephants trying to mate.

Forms of chemical communication along with scent marking among African elephants is done by males who are mating with the females in a clan. Around the clan the males will mark trees or bushes with their tusks or by secreting a substance onto the bush. African elephants have a herbivorous diet consisting of tree foliage, fruits, herbs, grasses, and wood including roots, twigs, and bark.
