Currently, the largest known mammal in the world is the blue whale, followed by the giant rhino, which is the oldest and largest. Elephants are probably ancient creatures.
1. Blue Whale
The blue whale is considered the largest known animal to have ever survived on earth, reaching a length of 33 meters and weighing 200 tonnes. The blue whale has a slender body and a bluish-gray back, but the color sometimes appears lighter in the water. Like other baleen whales, blue whales feed primarily on small crustaceans (such as krill) and small fish, sometimes including squid.
Usually, blue whales need to feed in marine areas with a depth of more than 100 meters during the day and can only come to the surface to feed at night. Blue whales begin mating in late fall and continue until the end of thewinter. Female whales typically give birth once every 2 to 3 years. After a gestation period of 10 to 12 months, they generally give birth to young at the beginning of winter.
The blue whale has a body that is extremely shocking to humans. Its tongue weighs more than 2 tons and its large mouth can suck up 90 tons of seawater. The weight of an adult blue whale can reach 200 tons and its length is more than 33 meters, about the same size as 'a yacht. Larger mammals provoke a feeling of shock, while smaller mammals provoke a feeling of infinite love and compassion.
2. Giant Rhino
There are many types of giant rhinoceros, but the largest among them is the Junggar giant rhino, which was first discovered in Xinjiang, China. the largest species that has ever existed on earth. The largest land mammal. The most complex skeletonThe existing in China is now on display at the Turpan Regional Museum in Xinjiang. It measures 4 meters high and 8.9 meters long. It is estimated that it weighed up to 15 tonnes during its life. a true giant on earth.
3. Deinophorus
Deinophorus is the largest individual that ever existed in the order Elephantidae. It was widespread in Asia, Africa and Europe 5 million years ago. The biggest difference between it and modern elephants is that its tusks do not grow on the upper jaw, but on the lower jaw, and are curved downward. Scientists believe the downward-curving tusks were used for digging roots or peeling bark. Based on existing fossils, it is deduced that the height of the dinosaur was more than 4 meters and its weight was more than 10 tons. The largest species of dinosaur was the giant dinosaur, which lived near the Mediterranean Sea in the lateu Miocene. .
The largest whale in the world is the blue whale. The blue whale is the largest creature found in the ocean to date, and it is also the largest animal existing on earth, with a length of over 33 meters and a weight of over 200 tonnes.
The blue whale is the largest creature living on this earth. Their length can reach 33 meters and their weight can exceed 181 tonnes. The body of the blue whale is relatively thin, and the color of its back is blue-gray.
Not only are they the largest whales, but also the largest living mammals. Their weight is equivalent to that of a twenty-five year old baby elephant, and their head is very long and large. More than fifty people can stand on their tongues and their hearts are as big as our cars.
The current situation of blue whales:
They have no natural enemies as adults andThe average lifespan of blue whales is between 80 and 90 years, which is longer than the average lifespan. lifespan of humans. Therefore, for over 1.5 million years until modern times, it has happily roamed the ocean.
However, from the end of the 19th century, a "massacre" of blue whales began quietly around the world, which resulted in the blue whale, even with the largest body, n is not immune to human greed.
In the 360 million square kilometers of ocean, there are today only 10,000 to 24,000 blue whales (estimated data from 2014). You should know that at the beginning of the 20th century, the number of blue whales there was increasing. There were still blue whales. There are at least more than 400,000 head.
In other words, in just over a hundred years, only a “fraction” of blue whales remain, and the conservation level has gone from not of concern to endangered(IN). due to Given by "Whaling".
