What is the largest animal in the world, including primitive

In terms of weight, it's the blue whale. If you compare the area or volume, it is the Arctic jellyfish.

From ancient times to the present day, the largest animal in the world is the Zen blue whale. He Chen's shirt.

The blue whale is not only the largest animal from ancient times to the present day, but also the largest mammal. The blue whale's heart weighs about 600 to 700 kilograms, its lungs weigh 1,500 kilograms, its tongue weighs 30 tons, the total amount of blood weighs about 8 to 9 tons, its intestines are straightened for more than 200 meters, and it has to eat tons of fish, shrimp, algae and other foods every day and night.

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.

c.Hippopotamus. Answer: B

The blue whale (scientific name: balaenoptera musculus) is a marine mammal premammal belonging to the suborder baleen whales. There are four subspecies.

The blue whale is considered to be the largest animal known to have ever lived on Earth, reaching up to 33 meters long and weighing 181 tons. The blue whale has a slender body and a blue-gray back, although it can sometimes be lighter in the water.

The largest animals in existence in the world are the blue whale, which is the largest in the world by weight, and the Arctic jellyfish, which is known for its length.

1. The blue whale is a kind of marine mammal that belongs to the suborder baleen whales. There are four subspecies. The blue whale is believed to be the largest animal known to have ever survived on Earth, reaching up to 33 meters long and weighing up to 181 tons.

Blue whales have a slender body with a blue-gray back, which looks lighter in the water. Blue whales feed mainly on small crustaceans (e.g. krill) and small fish, sometimes squid. Blue whales begin mating in late autumn and continue until late winter, with females usually giving birth every 2 to 3 years, and after a nucleation and 10 to 12 months of gestation, they usually give birth to calves in early winter.

2. The Arctic jellyfish is a lower coelenterate, which belongs to the phylum Coelenterates and the class Bowls Jellyfish taxonomicly. The Arctic jellyfish distributed in the Atlantic Ocean has a diameter of up to one meter from its canopy to a diameter of eight tentacles, each with about 150 tentacles. Each tentacle stretches for more than 40 meters and can shrink to only one-tenth of its original length in a second.
