Tip 1: The most difficult animal in the world
There are a lot of different animals in the world. All of them are very different from each other. Some live in the sea, others live on land. Some eat plants, others are predators. Some of them are small, others are huge and heavy.
The heaviest aquatic animal
The largest and heaviest aquatic animal in allthe world is by right a blue whale. Its length can be about 30 meters, and the weight starts from 180 tons and more. This animal has a dark blue color with bluish shades on the sides. The heart of a blue whale can weigh about 600 kilograms, and the language is about 2.5 tons, which in its size can be compared to an elephant.The volume of light blue whale in its size exceeds three thousand liters, which is an absolute record among all known animals.Feed on such whales as tiny organisms,which live in the sea and have the name - krill. On the day, a blue whale can eat up to 40 million individuals of such organisms. Most often blue whales prefer to keep alone or be paired. Such animals communicate by echolocation. The sound that blue whales utter when communicating is similar to the sound of a working jet and can be carried over huge distances, more than one thousand kilometers. Female blue whales give birth to their young once in three years after a previous pregnancy, which lasts about a year. The weight of the newborn kitten varies within 3 tons.
The blue whale is a fairly peaceful animal and has lost its warlike abilities, which contributed to the almost total extermination of this species.
The largest and heaviest land animal
The largest land animal is considered to beAfrican elephant. The animal is characterized by a heavy massive body, a short neck and a large head, as well as huge ears and thick limbs. The weight of a male African elephant can reach 6 tons, a length of about 7 meters and a height of just over 3 meters. Female animals weigh almost half as much. Their growth is about 2.5 meters, and the length is about 5 meters. Adult elephants, because of their large size, most often do not have enemies in their natural habitat, but small elephants are often exposed to bloodthirsty attacks from crocodiles, lions, hyenas and leopards. According to the latest statistical calculations, the population of these animals in the wild is about 550 thousand individuals. The largest killed animal is the African elephant, who was shot in Angola, his weight was more than 12 tons, which is a record.Tip 2: Which animal on earth is the oldest
The most ancient animals on Earth are socalled Archaean. These are microorganisms that can survive in the most difficult conditions. In addition arhebaktery, on Earth there are other "long-livers" - ants. They are generally contemporaries of dinosaurs.
The most ancient creatures on Earth are the arhebacteria
According to research by zoologists, the mostthe ancient animals on Earth are the so-called archebacteria (archaea). A phenomenal feature helps them to survive. The fact is that these microorganisms live in conditions in which no other organism will simply survive. This is hard to believe, but the Archaeans survive at temperatures up to 90 ° C and in conditions of high salinity.Today, modern cosmetology uses arhebacteria in order to improve the structure of the skin.Scientists believe that archebacteria arethe founders of the beginning of life on Earth. And all this is due to their phenomenal vitality under extreme conditions. Archeans are found even in the Dead Sea, where in general there are almost no conditions for life. Due to their miraculous vitality, these ancient microorganisms live in various parts of the world. For example, archaea occur in hot spring waters, as well as in conditions of high acidity, i.e. in acidic environments. It can be a seabed, and a rock.
Ants - one of the oldest inhabitants of the Earth
These insects are rightfully considered one of thethe oldest inhabitants of the Earth. They are real contemporaries of dinosaurs. Moreover, their unique intellect and a very complex social organization have long been of interest to scientists. It is curious that for millions of years of their existence, these insects almost did not change their external appearance. The morals are found almost everywhere. According to statistical data, today more than 15 thousand different kinds of ants have been described. Moreover, each species has its own peculiarities, manifested in the structure of the trunk, in appearance and, of course, in the way of life. Their social organization is simply amazing: from time immemorial ants live only by families. In each of these families there is one or more females. The backbone of any ant community is made up of sterile worker ants.For several years scientists have been trying to find out whetherants by reason. It turned out that they do not. But there were many other discoveries. For example, to transmit information to each other, ants use special pheromones.These insects have a very developed sense ofterritorial ownership. Woe to that stranger-alien who breaks the border. If both insects meet in any neutral territory, then their jaws will be menacingly spread and they will part with the world.
