What is the largest animal in the world? On what basis?

Hello, glad for your question!!

What is the largest animal in the world? On what basis?

The question is a bit less rigorous, the largest animal in the world is divided into past and present.

Now the largest animal in the world - the blue whale, the blue whale is known to be the largest mammal in the world, there is no one. Blue whales are so large that it is difficult to measure their weight. So far, scientists at the National Marine Mammals Laboratory have accurately measured that the largest blue whale is a 220-ton female who can reach 33 meters in length.

The gestation period of the blue whale is 11 months, and the newborn calf is about 7 meters long and weighs more than 2 tons. And the blue whale is also a long-lived animal, generally living up to 120 years old.

In the past, the largest animal in the world, as far as archaeologists are concerned, is the New Zealand ichthyosaur, which is 38 meters long and weighs tons. Its fossil was discovered in New Zealand in 1878 and is a vertebrae with a diameter of millimeters. Later, because the vertebrae were lost, it was not recognized by most scientists.

But what exists does not become non-existent because it is lost. So the New Zealand big ichthyosaur exists.

Those who admit the existence of the Great Ichthyosaurus in New Zealand believe that it belongs to the genus Sastetrasaurus, and it is deduced that it weighed tons. However, based on the fact that the genus Ichthyosaurus is the largest of the genus, the New Zealand ichthyosaur is most likely to be the genus Ichthyosaurus, so it can be inferred that the weight of this New Zealand ichthyosaur is tons.

In fact, the ton is far from the upper limit of the weight of the New Zealand ichthyosaur, because no one can rule out the possibility that this vertebra is the smallest vertebrae of the New Zealand ichthyosaur and that the New Zealand ichthyosaur is a juvenile ichthyosaur.

So, the New Zealand Ichthyosaurus is the largest animal ever created.

I hope mine can help you, if there is any shortcoming, welcome to add.

The largest animal in the world is the blue whale, which is very large and a sea creature.

The blue whale, an endangered species, is the largest mammal in the world, distributed in temperate waters, and has been documented.

The largest animal in the world is currently the blue whale, which is the largest according to scientific measurements.

1. The blue whale is the largest and heaviest animal in the world since ancient times.

2. It looks like a swarthy hill when it appears on the surface of the sea. Dinosaurs were once behemoths on Earth, with the largest being up to 25 meters long and weighing nearly 50 tons, but they were small compared to blue whales. The largest blue whale ever caught by humans is as long as a meter long and weighs 170 tons, which is equivalent to 27 elephants or 150 cows, and it takes as many as 43 vehicles to pull the blue whale in a 4-ton truck.

Zhuangzi said that there is a big bird called Peng, which is derived from a big fish called Kun. Legend has a big fish named Kun, long does not know how many miles, width does not know how many miles, one day rushing like the sky, become a big bird can fly several miles, the name is Peng.

The ancients had a poem: Yunkai Hengyue wind and rain stopped, Kunpeng hit the waves from the beginning of the sea crossing, what is the need to worry, the three-foot cold river Donglin finger.

Nowadays, Kunpeng is often used as a metaphor for some magnificent things, and a common saying says: "Learn to be a Kunpeng and fly thousands of miles, not a nest of birds." ”

Zhuangzi Getaway": "There is a fish in Beiming, and its name is Kun. The Kun is so big that I don't know how many thousands of miles it is.

Turned into a bird, its name is Peng. Peng's back. I don't know how many thousands of miles it is.

Angry and flying, its wings are like clouds hanging from the sky, it is a bird, and the sea will be in vain in Nanming, Nanming, Tianchi also. "This extremely peculiar animal, which has the body of a giant bird and a giant fish, has always been thought to be a myth. But recently, I saw from Li Zhouzhao's report in foreign zoology that sea whales inhabit the sea and sometimes erect their tails out of the sea, and their tails are so huge that they are shaped like bird wings.

In ancient times, the Bohai Sea was called the North Sea, that is, the North Underworld. According to historical records, sea whales were often seen in the Qin and Han dynasties in the Bohai Sea. Whales are extremely large, up to 30 meters long (the largest living animal), and Zhuang Yu is not exactly an allegory, but refers to the sea whales in the Bohai Sea.

The blue whale (scientific name: balaenoptera musculus) is a marine mammal belonging to the suborder Baleen Whales. The blue whale is believed to be the largest animal that has ever survived on Earth, reaching up to 33 meters long and weighing up to 181 tons.

Because blue whales are so large, it's hard to measure their weight. Many whalers hunt blue whales that don't fully weigh them, as they first cut the whales into easy-to-handle sizes. This leads to an underestimation of the total weight of blue whales because they lose their blood and body fluids.

Despite this, blue whales weighing 150 to 180 tonnes (160 to 190 short tonnes) and measuring 27 metres in length have been recorded. A 30-meter-long specimen is considered by the National Marine Mammal Laboratory to weigh more than 180 metric tons (200 short tons). So far, scientists at the National Marine Mammals have accurately measured that the largest blue whale is a 177-tonne (196-ton) female.

From ancient times to the present day, the largest land animal that has ever appeared on land is the Argentinosaurus, and the ocean is the blue whale.

Blue whale! The blue whale can reach a length of 33 meters and weigh 190 tons, which is equivalent to the weight of 33 elephants or more than 300 cattle, and it weighs 4 tons on one tongue. It is also immensely powerful, with 1,250 kilowatts and a 588-kilowatt motor boat, making it the largest animal ever seen on Earth.

This is the bounty of the sea, and only in the sea can it grow so big: first, because of its abundance of food, the blue whale feeds on krill, which is too small to be compared to it. This shrimp is abundant and easy to catch, and can afford to raise these big-bellied men.

The second is that the buoyancy of the water is large, supporting the huge body of the blue whale. The African elephant is the largest animal on land, weighing about 5 tons, and if the African elephant gains weight, its limbs will not be able to support it, so it cannot grow too big. But this is not the case in the sea, where animals are basically weightless and can float no matter how big they are.

However, it cannot be increased indefinitely, and beyond a certain limit, the functions of organs such as the heart and lungs cannot meet the needs.

The largest animal in the world: the blue whale (the blue whale is not only the largest cetacean, but also larger than the largest dinosaur ever living on earth, and is the largest of all animals known since ancient times, with a general body length of 2400-3400 cm and a weight of 150,000-200,000 kg, that is, its weight is equivalent to the weight of more than 25 African elephants, or the weight of 2000-3000 people combined. )

The largest amphibian in the world: the giant salamander (also known as the giant salamander) The largest animal on land: the African elephant.

The world's largest carnivore - brown bear (brown bear in ancient China called Zhen, carefully search for slag body length is generally 150-200 cm, tail length 13-16 cm, weight 150-250 kg, larger can reach 400-600 kg, the highest record for living on Kodiak Island, Alaska, USA, body length of about 400 cm, weight of 757 kg, not only the behemoth in the bears, but also the world's largest carnivore. )

At the moment, the land creatures are elephants, and the sea creatures are blue whales.

The largest animal at the moment is the blue whale in the sea.

The world today: the blue whale.
