Among animals, as well as among people, there are champions worthy of getting into the Guinness Book of Records. Some of them are recognized as the strongest, others - the fastest. And some can only boast of their huge weight or number of teeth. But today we are only interested in one category, which we will discuss below.
There are many land and sea creatures on Earth that can compete for the title of the heaviest animal in the world. If you ask passers-by on the street which animal is the heaviest, you can hear a variety of answers: an elephant and a buffalo, a whale and a shark, a hippopotamus and even a giraffe. But in this article, we must name the only terrestrial inhabitant whose weight and size significantly exceeds the parameters of competitors. You will find out how much an elephant and a hippopotamus weigh, and whether they can be considered the heaviest. First, let's get acquainted with some giants that live on land.
Kodiak bear
This is not the heaviest land animal, but I would like to mention it in our review. A subspecies of brown bears, which in many countries is under state protection. The average weight of a male exceeds 700 kilograms, and that of a female - 300 kilograms. At the same time, it must be said that there have been cases when the weight of the kodiak exceeded a ton.
White (polar) bear
This is the heaviest carnivore that lives on land. The largest polar bear weighed a little over a ton and had a body length of about three meters. The height of the predator standing on its paws was 3.39 m. The average body length of male polar bears is about two and a half meters, the height at the withers is up to one and a half meters, and the average weight reaches eight hundred kilograms. Bears are about half the size of males, their weight does not exceed 300 kilograms. It is interesting that a hundred thousand years ago (during the Pleistocene epoch) a huge polar bear lived on earth, the weight of which exceeded 1.2 tons, and the size was four meters in length.
Hippo
This is one of the largest and heaviest animals living on Earth. The weight of large males often exceeds four tons, so the hippopotamus is a worthy competitor to the rhinoceros in the fight for second place in terms of mass among terrestrial inhabitants.
Now the hippopotamus in natural conditions is found only in Africa, south of the Sahara, although in ancient times, for example, it had a wider range. This giant lived in North Africa, and scientists also believe that he livedin the Middle East. However, by the early Middle Ages, it was destroyed in these regions. In 2006, the International Union for Conservation of Nature recognized the hippopotamus as vulnerable.
The number of these animals at that time did not exceed one hundred and fifty thousand heads. The natives of Africa destroy hippos primarily for meat, so bloody wars and instability in many countries of the continent force starving people to look for food, thereby causing great damage to the animal population.
African Elephant
This is the world's heaviest land animal. From brothers living on other continents, he differs not only in body weight, but also in huge ears, which help him feel most comfortable under the rays of the scorching African sun.
The tusks of these giants are highly valued. It was they who nearly became the cause of the complete extermination of elephants. A huge number of animals were killed for expensive trophies. The situation with the disappearance of the population was saved by nature reserves and National parks.
The weight of African elephants is impressive: adult males weigh more than 7.5 tons, but at the same time, the heaviest land animal is very mobile, swims well and feels confident even on rocky terrain. African elephants are herbivores. They feed on young shoots of trees and shrubs, grass. An adult absorbs up to one hundred kilograms of green mass per day. Animals form small herds9-14 individuals. Besides humans, elephants have no natural enemies.
Knowing how much an elephant and a hippopotamus, different types of bears weigh, you can easily determine the leader in body weight. This is, of course, the African elephant, which is the heaviest land animal. It's time to get acquainted with the underwater inhabitants. Perhaps the heaviest animal in the world lives in the depths of the sea.
Whale shark
This is the largest shark among its relatives. Despite its impressive size (up to twenty meters) and impressive weight (up to twenty tons), this is not the heaviest marine animal. Representatives of this species live in the southern and northern seas. Northern individuals are much larger.
This gray-brown giant, covered with white spots, the location of which is unique to each individual, lives for about seventy years. They feed by filtering out plankton and filtering the water. During the day, the shark passes 350 tons of water and eats more than two hundred kilograms of plankton. The mouth of this "fish" can accommodate up to five people, its jaws are covered with fifteen thousand small teeth.
But these inhabitants of the depths are never the first to attack a person, and many scuba divers even touch them. Whale sharks are little studied and very slow. Their number is small, so the species is listed in the Red Book.
Sperm whale - toothed whale
Another very large, but not the heaviest animal. The weight of an adult male is about seventy tons, and its body length reaches twenty meters. The body shape of the sperm whale (in the form of a drop) allows it tomake long trips in a short time (during the migration period).
Sperm whales, unlike whales, keep in groups of up to 150 animals. The representative of the species has a huge rectangular head, compressed on the sides. It makes up a third of the entire body of the whale. Below is a mouth with cone-shaped teeth. In these animals, the lower jaw is mobile and can open almost 90 degrees, which helps to capture rather large prey.
Sperm whales (sperm whales) have one blowhole located in front of the head. It is slightly shifted to the left. Sperm whales feed on cephalopods and fish. But at the same time, they can attack seals, dive to the bottom for squid, crabs, sponges and mollusks, descending to a depth of more than 400 meters.
The blue whale is the heaviest animal
This is really the largest animal on our planet. The length of the body reaches thirty meters, and the mass of the blue whale is 180 tons and more. In this species of whale, females are slightly larger than males.
It's hard to imagine, but the tongue of this sea giant weighs about 2.7 tons, which is comparable to the weight of an Indian elephant. The blue whale has the largest heart among mammals: it weighs 900 kilograms. To imagine its dimensions, look at the Mini Cooper car. They are comparable in size and weight.
The heaviest animal in the world has an elongated and rather slender body. On a huge head are locateddisproportionately small eyes. The pointed muzzle has a wide lower jaw. The blue whale has a blowhole, from which, when exhaling, it releases a fountain of water, reaching a height of 10 meters. There is a clearly visible longitudinal ridge in front of the blowhole - the so-called breakwater.
This giant has a dorsal fin that is strongly shifted back. Compared to its body size, it is quite small and triangular in shape. Its rear edge is covered with scratches, forming an individual pattern for each whale.
Physiological characteristics
The sense of smell and vision in the blue whale are rather poorly developed. But the sense of touch and hearing are excellent. Representatives of this species of whales have a huge lung capacity, and the amount of blood exceeds eight thousand liters. Despite its impressive size, the blue whale has a narrow throat with a diameter of only ten centimeters. The pulse of this huge animal is 5-10 beats per minute and rarely rises to 20 beats.
The skin of the blue whale is even and smooth, except for the stripes on the belly and throat. These animals are practically not overgrown with crustaceans, which often settle on other whales in large numbers. The color of the animal is predominantly gray with a blue tint. The head and lower jaw are usually painted a darker, more intense grey.
