Today, the African elephant is the largest mammal in the world that lives on land, and the second largest among all animals living on earth.
The championship was given to the blue whale. On the territory of the African continent, the elephant is the only representative of the proboscis family. Amazing strength, power and behavioral characteristics have always aroused special interest, delight and admiration among people. Looking at an elephant, one gets the impression that it is overweight, clumsy, and sometimes even lazy. However, this is not at all true. Despite their size, elephants can be very agile, fast and agile.
Origin of the species and description

The African elephant is a chordate mammal. It is a representative of the proboscis order and the elephant family, a genus of African elephants. African elephants, in turn, are divided into two more subspecies: forest and savanna. As a result of numerous examinations, the estimated age of the mammal’s existence on earth has been established. It is almost five million years old. Zoologists claim that the ancient ancestors of the African elephant led a predominantly aquatic lifestyle. The main source of nutrition was aquatic vegetation.
The ancestor of the African elephant is called Meriteria. Presumably it existed on earth more than 55 million years ago. His remains were discovered in the territory of modern Egypt. It was small in size. Corresponded to the body size of a modern wild boar. Meryterium had short but well-developed jaws and a small trunk. The trunk was formed as a result of the fusion of the nose and upper lip in order to easily move through the water space. Outwardly, he looked like a small hippopotamus. Merytherium gave rise to a new genus - paleomastodon.

His time was in the Upper Eocene. This is evidenced by archaeological finds on the territory of modern Egypt. Its size was much larger than the size of the meretherium's body, and its trunk was much longer. The paleomastodon became the ancestor of the mastodon, which in turn became the ancestor of the mammoth. The last mammoths existing on earth were on Wrangel Island and were exterminated about 3.5 thousand years ago.
Zoologists claim that about 160 species of proboscis have become extinct on earth. Among these species there were animals of incredible size. The weight of some representatives of certain species exceeded 20 tons. Today, elephants are considered quite rare animals. There are only two species left on earth: African and Indian.
Appearance and features

The African elephant is truly enormous in size. It is much larger than the Indian elephant. The animal reaches a height of 4-5 meters, and its weight is about 6-7 tons. They have pronounced sexual dimorphism. Female individuals are significantly inferior in size and body weight. The largest representative of this species of elephant reached a height of approximately 7 meters, and its weight was 12 tons.
African giants are distinguished by very long, huge ears. Their size is approximately one and a half to two times the size of the ears of an Indian elephant. Elephants tend to escape from overheating by flapping their huge ears. Their length can reach two meters. Thus, they lower their body temperature.
The huge animals have a massive, large body and a very small tail, just over a meter long. The animals have a large, massive head and a short neck. Elephants have powerful, thick limbs. They have a peculiarity in the structure of their soles, thanks to which they easily move both on sand and on flat terrain. The area of the feet may increase or decrease when walking. The forelimbs have four fingers, the hind limbs have three.
Among African elephants, just like among people, there are left-handers and right-handers. This is determined depending on which tusk the elephant uses most often. The skin of the animal is dark gray in color and covered with sparse hair. She is wrinkled and rough. However, the skin is very sensitive to external factors. They are very vulnerable to the direct rays of the scorching sun. To protect themselves from the sun, female elephants hide their cubs in the shade of their bodies, and adult elephants sprinkle themselves with sand or throw mud on them.
With age, the hair on the surface of the skin is wiped off. Old elephants have no hair on their skin, with the exception of a tuft on the tail. The length of the trunk reaches two meters, and the weight is 130-140 kilograms. It performs many functions. With its help, elephants can pinch grass, grab various objects, pour water on themselves, and even breathe through their trunk.
With the help of its trunk, an elephant is capable of lifting weights weighing up to 260 kilograms. Elephants have powerful, heavy tusks. Their weight reaches 60-65 kilograms, and their length is 2-2.5 meters. They constantly increase with age. This type of elephant has tusks in both female and male individuals.
The largest whale in the world
The blue whale is the largest whale in the world. It is also called the vomit or blue whale. The body weight of this mammal reaches 150 tons, and its length is 30 meters. Its heart weighs about 1,300 feet (600 kg), making it the largest such organ of any living thing. The blue whale also has large lung volumes: they can exceed 3000 liters.
Interesting Facts:
- the weight of a blue whale's tongue can reach about 2.8 tons, which is comparable to the weight of an average-sized Asian elephant;
- individuals of blue whales usually stay solitary and rarely gather in schools;
- Blues reproduce extremely slowly;
- The number of blue whales numbers no more than 10 thousand individuals.
Where does the African elephant live?

African elephant populations used to be much larger. Accordingly, their habitat was much larger and wider. With the increase in the number of poachers, as well as the development of new lands by humans and the destruction of their natural habitat, their range has decreased significantly. Today, the vast majority of African elephants live in national parks and reserves.
Geographical regions of African elephants:
- Kenya;
- Tanzania;
- Congo;
- Namibia;
- Senegal;
- Zimbabwe.
African elephants choose forests, forest-steppes, foothills of mountains, swampy rivers, and savannas as their habitat. For elephants, it is necessary that in their habitat there is a pond, an area with forest as shelter from the scorching African sun. The main habitat of the African elephant is the territory south of the Sahara Desert.
Previously, representatives of the proboscis family lived on a vast territory with an area of 30 million square kilometers. Today it has decreased to 5.5 million square meters. It is unusual for African elephants to live in one territory all their lives. They can migrate long distances in search of food or to escape extreme heat.
Habitat
Asian elephants live in Nepal, India and parts of Southeast Asia. The main habitat is low-growing and tropical forests. During dry months they are often found near river banks.
African bush elephants (savanna elephants) live in eastern, central and southern Africa, preferring lowland and mountain forests, floodplains, all types of wooded areas and savannas. Forest elephants are found in the Congo Basin and western Africa, in moist, semi-deciduous tropical forests.
What does the African elephant eat?

African elephants are considered herbivores. Their diet contains only food of plant origin. One adult eats about two to three tons of food per day. In this regard, elephants eat food most of the day. About 15-18 hours are allotted for this. Males require more food than females. Elephants spend several more hours a day searching for suitable vegetation. There is an opinion that African elephants are madly fond of peanuts. In captivity they consume it very willingly. However, under natural conditions they do not show interest in it and do not specifically look for it.
The basis of the African elephant's diet is young shoots and lush green vegetation, roots, branches of bushes and other types of vegetation. During the wet season, animals feed on lush green plant varieties. It could be papyrus, cattail. Elderly individuals feed mainly on marsh plant species. This is explained by the fact that with age, teeth lose their sharpness and animals are no longer able to eat solid, rough food.
Fruits are considered a special delicacy; forest elephants consume them in large quantities. In search of food, they can enter agricultural lands and destroy the fruits of fruit trees. Due to their enormous size and the need for large quantities of food, they cause serious damage to agricultural land.
Elephants begin to eat plant foods when they reach two years of age. After three years, they completely switch to an adult diet. African elephants also require salt, which they obtain by licking licks and digging in the ground. Elephants need a very large amount of fluid. On average, one adult consumes 190-280 liters of water per day. During periods of drought, elephants dig huge holes near river beds in which water accumulates. In search of food, elephants migrate over vast distances.
Features of character and lifestyle

Elephants are herd animals. They live in groups of 15-20 adults. In earlier times, when animals were not in danger of extinction, the group size could reach hundreds of individuals. When migrating, small groups gather into larger herds.
The head of the herd is always a female. Females often fight with each other for primacy and leadership, when large groups are divided into smaller ones. After death, the place of the main female is taken by the oldest female individual.
In the family, the orders of the eldest female are always strictly followed. As part of the group, along with the main female, there live young, sexually mature females, as well as immature individuals of any sex. Upon reaching 10-11 years of age, males are expelled from the herd. At first, they tend to follow their family. Then they completely separate and lead a separate lifestyle, or form male groups.
There is always a very warm, friendly atmosphere in the group. Elephants are very friendly with each other and show great patience with little elephants. They are characterized by mutual assistance and help. They always support weakened and sick family members, standing on both sides so that the animal does not fall. An amazing fact, but elephants tend to experience certain emotions. They may be sad, upset, bored.
Elephants have a very sensitive sense of smell and hearing, but poor eyesight. It is noteworthy that representatives of the proboscis family can “hear with their feet.” There are special hypersensitive areas on the lower extremities that perform the function of capturing various vibrations, as well as the direction from which they come.
- Elephants are excellent swimmers and simply love water treatments and bathing.
- Each herd occupy its own specific territory.
- Animals tend to communicate with each other by making trumpet sounds.
Elephants are recognized as the animals that sleep the least. Such huge animals sleep no more than three hours a day. They sleep standing up, forming a circle. During sleep, the head is turned to the center of the circle.
Social structure and reproduction

Females and males reach sexual maturity at different ages. It depends on the conditions in which the animals live. Males can reach sexual maturity at the age of 14-16 years, females slightly earlier. Often, in the struggle for the right to enter into mating relationships, males fight and can cause serious injuries to each other. Elephants tend to look after each other very beautifully. The elephant and the female elephant, having formed a pair, move away together away from the herd. They tend to hug each other with their trunks, expressing their sympathy and tenderness.
There is no mating season for animals. They can breed at any time of the year. During mating, they can show aggression due to high testosterone levels. Pregnancy lasts 22 months. During pregnancy, other female elephants of the herd protect and help the expectant mother. Subsequently, they will take part of the care of the elephant themselves.
When the birth approaches, the elephant leaves the herd and retires to a secluded, quiet place. She is accompanied by another female elephant, who are called "midwives." A female elephant gives birth to no more than one baby. The weight of the newborn is approximately one hundredweight, and the height is approximately one meter. Babies have no tusks and a very small trunk. After 20-25 minutes the cub gets to its feet.
Baby elephants stay with their mother for the first 4-5 years of life. Mother's milk is used as the main source of nutrition during the first two years.
Subsequently, babies begin to eat foods of plant origin. Each female elephant produces offspring once every 3-9 years. The ability to bear children remains until 55-60 years of age. The average life expectancy of African elephants in natural conditions is 65-80 years.
Offspring
At birth, a baby elephant is about a meter tall and weighs 55-120 kg. As a rule, babies are born with hair, a short trunk and are directly dependent on the mother and other members of the herd. They do not need a trunk, since milk from the mother goes into the mouth. Baby elephants try to stay as close as possible to their mother or another nursing female. During the first year of life, on average, they gain 1-1.3 kilograms of weight per day. If the baby is in distress, other members of the herd often come to his aid.
Despite prolonged gestation and protection, elephant calves need to gradually move up the social levels of the herd and establish their position in it. The cubs spend their days learning to walk on four legs in one direction, trying to cope with huge ears and mastering the work of their trunks. At first they are very clumsy, but all the time they learn to control their body. Upon reaching 2-3 years of age, elephant calves stop feeding on their mother's milk.
Natural enemies of African elephants

When living in natural conditions, elephants have practically no enemies among representatives of the animal world. Strength, power, as well as enormous size leave no opportunity even for strong and fast predators to hunt it. Only weakened individuals or small elephant calves can become prey for predatory animals. Such individuals can become prey for cheetahs, lions, and leopards.
Today, the only and very dangerous enemy remains man. Elephants have always attracted poachers, who kill them for their tusks. Elephant tusks are of particular value. They have been highly valued at all times. Valuable souvenirs, jewelry, decorative elements, etc. are made from them.
A significant reduction in habitat is associated with the development of ever new territories. Africa's population is constantly growing. As it grows, more and more land is required for housing and agriculture. In this regard, the territory of their natural habitat is destroyed and rapidly declining.
Yossi
Relatively recently, the title of the world's largest elephant was given to an animal named Yosi. He lives in the Israeli Safari Zoo and is quite old. His age has already exceeded three decades, and he weighs 6000 kg. Yossi’s tail is 100 cm long, his ears are about twenty meters long, and his trunk is two and a half meters long. His height is about four meters.
The elephant is the so-called "elder" of the zoo
Because of his size, he has difficulty pushing through the gate of his pen, he even has to crouch down to do this. Veterinarians agree that such physical exercises do not harm him, but, on the contrary, are beneficial.
Population and species status

At the moment, African elephants are not in danger of complete extinction, but they are considered a rare, endangered species of animal. Mass extermination of animals by poachers was noted in the mid-19th and early 20th centuries. During this period, an estimated one hundred thousand elephants were killed by poachers. Elephant tusks were of particular value.
Piano keys made of ivory were especially prized. In addition, the huge amount of meat made it possible to feed a large number of people for a long time. Elephant meat was mainly dried. Jewelry and household items were made from the hair and tassels of the tail. The limbs served as the basis for making a stool.
African elephants are on the verge of extinction. In this regard, the animals were listed in the International Red Book. They were given the status of "endangered species". In 1988, hunting African elephants was strictly prohibited.
Violation of this law was criminally punishable. People actively began to take measures to preserve populations, as well as increase them. Nature reserves and national parks began to be created, on the territory of which elephants were carefully protected. Favorable conditions were created for them to reproduce in captivity.
In 2004, the African elephant managed to change its status from “endangered species” to “vulnerable” in the International Red List. Today, people from all over the world come to African national parks to see these amazing, huge animals. Ecotourism involving elephants is common to attract large numbers of visitors and tourists.
The largest crocodile in the world
The largest crocodile in the world is Cassius Clay, included in the Guinness Book of Records as the largest reptile that lives in captivity. Northern Australia's most famous resident was caught in the wild 26 years ago. He was settled with the owner of Green Island Farm in Marineland Melanesia.
The crocodile got its name in honor of the legendary boxer Clay Cassius. The body length of the crocodile is 5 meters 48 centimeters; and the weight is a whole ton.
It should be noted that at the end of May of this year, Cassius Clay turned 110 years old. A twenty-kilogram chicken cake was a gift for his birthday.
