The rarest animals in the world. The largest animal in the world. The heaviest land animal in the world: African elephant

Our world is full of creatures big and small, short and tall. The blue whale is a marine mammal belonging to the suborder baleen whales. At 30 meters long and weighing 180 metric tons or more, it is the largest known animal to have ever existed. The Blue Whale's tongue weighs about 7 metric tons, the size of an average Asian elephant, and its heart weighs about 600 kg and is the largest known in any animal. Not only is the heart similar in size to a mini coupe, but it is also comparable in weight.

The Blue Whale is thought to feed almost exclusively on small shrimp-like creatures called Krill. During summer season feeding The Blue Whale takes flight, consuming an astonishing 6 metric tons or more each day. The whale has a fascinating series of plates lined with bristles to help it filter its main food source, plankton, from the water. At the end of each plate there are what appear to be whisker-like long bristles to help retain minute prey. After removing the water from its mouth, the whale licks these bristles with its fleshy tongue.

Although the blue whale is a deep sea hunter, as a mammal it must come to the surface of the sea to breathe. Blue whales sometimes swim in small groups, but usually swim alone or in pairs. They are believed to form close bonds. The African Bush elephant is the largest living land animal, with males reaching 6-5 meters in length, 3 meters high at the shoulder and weighing 6 tons. The mature African bush usually has no natural predators due to its large size, but calves are vulnerable to attacks by lions and crocodiles, as well as attacks by leopard and hyena.

The elephant's brain is the largest of all land mammals, weighing over 5 kg. It is similar in structure to the human brain. Like humans, elephants must learn important behaviors as they grow. The African Booster Elephant Has Amazing Memories. The matriarch and other older women remember important information, such as the location of water bodies that allow elephants to survive long dry periods on the plains.

They communicate with everyone through touch, sound and smell. They use a wide range of sounds to talk to each other and even communicate at the infrasound level. The African Bush Elephant is able to recognize itself using mirrors. Self-awareness indicates a very high level awareness. So far, only cetaceans, magpies, humans and other primates have been found to recognize themselves in mirrors. There is substantial evidence that elephants mourn consensus. They even recognize the skulls of other elephants long after they have died, and even after their tusks have been removed.

Elephants carefully touch the skulls and tusks of dead people with their chests and feet. Giraffes are the tallest mammal in the world. Their long legs and neck help them eat leaves at the top tall trees that other animals cannot reach. They have long tongues and no teeth on the front of the upper jaw, which helps them tear leaves from branches. Male giraffes use their necks to fight, swinging them from side to side to pounce on their opponent.

Giraffes' long legs and necks make them the tallest of all mammals; about six feet, only the legs are taller than people. They have a distinct spotted coat, with no two giraffes having the exact same pattern. This means that giraffes can be individually identified from their coats, which is often used when studying wild giraffe populations. Giraffes live in the open plains, grasslands and savannas of Africa. They are most common in South and East Africa, but some smaller, more isolated populations live in western and central Africa.

The largest living predators are polar bear and the Kojak bear, a subspecies of brown bear. Since they have similar body sizes, it is unclear which is definitively larger. Bears are incredibly smart animals. They have far superior navigation skills to humans; great memories; big ratio between brain and body; and use tools in a variety of contexts from play to hunting.

Bears deeply upset others. Cubs are known to moan and cry when separated from their mothers. This can last for several weeks if their mothers are killed by hunters. Bears have excellent senses of smell, sight and hearing. They can smell food, young, mate or predators from miles away. Their excellent vision allows them to detect when fruits are ripe. Some species of Asian bears build nests in trees. They can use them for hiding, eating and even sleeping. Bears care deeply about family members.

They will risk their lives and even fight to the death to save a cub or sibling from danger. Bears were frequently noted in the cultures of many early civilizations. They were seen as a symbol of strength, power and love. The Vikings and Celts have many legends about the strength, security and valor of bears. The bear is a common national personification for Russia and Germany. The brown bear is the national animal of Finland.

The saltwater crocodile is the largest of all living reptiles. It is found in suitable habitats from Northern Australia through Southeast Asia on East Coast India. The saltwater crocodile is an opportunistic apex predator, capable of taking almost any animal that comes into its territory, either in the water or on land. The name saltwater crocodile water is misleading. They can live in brackish waters along coastline, as well as in freshwater rivers and swamps.

Saltwater crocodiles raise their young in freshwater areas. The locations of Australian crocodile nests are sometimes used as an indicator of how much rain can be expected in the upcoming wet season. Unfortunately, crocodiles don't always get this right. Many nests are flooded every year, killing the embryos. The eggs take 90 days to hatch. The sex of young saltwater crocodiles is determined by incubation temperature. When saltwater crocodiles about to hatch, they make chirping noises from their eggs.

The largest rodent in the world: Capybara, or guinea pig

Their mother helps them by digging them out of the nest. As soon as they hatch, she takes them to the edge of the water in her mouth and from there she watches over them until they can look after themselves. The runaway ostrich is the largest bird in the world. Ostriches have three stomachs. Unlike all other living birds, the ostrich excretes urine separately from feces. Ostrich exercise is aided by having only two toes on each foot, with a large nail on the big inner toe resembling a hoof.

Ostriches' wings have a span of about 2 meters and are used in mating displays, chick shades to cover the exposed skin of their upper legs and sides to retain heat, and as "rudders" to help them change direction while running. When threatened, although ostriches are powerful, their long legs can be formidable weapons, capable of killing a person or potential predator, like a lion with a forward strike.

Ostriches usually spend the winter months in pairs or alone, and during the breeding season and sometimes during extreme periods of no rainfall, they live in nomadic "herds" of five to 50 birds, led by an apex hen, who often travel with others grazing animals such as zebras or antelopes. Territorial fights between males for a harem of two to seven females usually last only a few minutes, but they can easily result in death by slamming heads into opponents.

Ostriches perform a complex mating ritual consisting of alternating wings until they attract a mate as they head into the mating area and he drives away any intruders. They graze until their behavior is synchronized, then feeding becomes secondary and the process takes on a ritualistic appearance. Then the rooster will excitedly again cover his alternating wings and begin to shake his count on the ground. It will then flap its wings sharply to symbolically clean out the nest in the dirt.

Then, as the chicken circles around him with her wings down, he will spin him around in a spiral. She will fall to the ground and he will begin to mate. The southern elephant seal is the largest carnivore living today. This size of seals shows extreme sexual dimorphism, perhaps the greatest of any mammal, with males typically five to six times heavier than females.

Its members are officially called Carnivorans, and the word "carnivore" can refer to any meat-eating organism. Carnivorans are the most diverse in size of any order of mammals, from the smallest weasel at just 25 grams and 11 centimeters to polar bear and the southern elephant seal. In the cool darkness 2 kilometers below the surface of the Southern Ocean, one of nature's greatest battles is being fought. One of the combatants is the kraken - the largest invertebrate known to exist, a colossal squid more than 12 meters long.

Spermaceti also softens the heads of whales, especially in men, who have much more than in women. This allows men to fight to hurt each other. However, there is no evidence that they take prey. Males have their own method of hunting. A study earlier this year found that females hunt in packs, grazing fat squid in "bait balls" like dolphins with fish. Young men live in "bachelor" pods and so can do the same, but as they get older they become lonely.
