Leeds fish
Leedsichthys problematicus, an extinct giant thick-stemmed fish that lived between 165 million and 155 million years ago in the mid-Jurassic Period, is considered the largest teleskeletal fish ever recorded and the largest fish on Earth.
The closest thing to a Leeds fish in the living fish is the bowfin fish, but the relationship between the two fish is still far apart. The name of the Leeds fish means "Leeds fish" and is named after the fossil collector Ephraim Nixon Leeds discovered its fossil in Peterborough, England, in 1886.
According to scientists, Leeds fish can grow to 8-9 meters long in the first 20 years of "raw fish". They then grow rapidly, growing to a maximum size of 27 meters in 40 years.
If Leeds fish could really grow that long, the largest modern fish whale shark wouldn't be able to match them. Moreover, it takes about 70 years for whale sharks to grow to a maximum length of 20 meters, while Leeds fish only need 40 years. This shows that Leeds fish grow faster than whale sharks.
Lion mane jellyfish
Lion mane jellyfish is one of the largest jellyfish in the world, however, the main length of the lion mane jellyfish is the tentacles, its umbrella body can reach two meters, there are eight groups of tentacles, up to 150, counting the tentacles, it can grow more than 35 meters, so the lion mane jellyfish weighs only about 400 kilograms. Longer than the blue whale.
It grows mainly in colder seas, including the Arctic Sea, the North Atlantic, the North Pacific Ocean and other seas, and rarely grows in areas below 42 degrees north latitude. There are similar species of jellyfish in the waters of Australia and New Zealand. Lion-maned jellyfish is a creature that can cause death.
Ancient insects
We are so familiar with dinosaurs that many other prehistoric creatures or prehistoric periods are overlooked. In fact, there have been many colorful eras on the earth, including the Carboniferous Period.
The Carboniferous Period is 300 million years old, and the earth at that time was the world of insects. The ancient dragonfly has a wingspan of up to 1.2 meters, the ancient spider is also the size of a human head, and the prehistoric centipede is up to 3 meters long, standing up and about the same height as a person!
Double-cavity fragile dragon
The two-chamber fragile dragon was the largest and heaviest dinosaur in history, the largest even surpassing the blue whale, up to 35 meters long.
The largest fossil of a diplodocus found so far is incomplete and its size cannot be fully determined. However, scientists have enlarged it in the same proportion according to the size of the beam dragon similar to it, and the length even exceeds 58 meters!
blue whale
The blue whale is the largest animal in the world today and the largest of all the animals in earth's history that have appeared and have exact data.
The weight of a blue whale can reach up to 180 tons, which is equivalent to 25-30 African elephants. Its tongue alone weighs 2 tons, equivalent to the weight of 15 adults. The arteries of the blue whale are enough for a small child to crawl freely.
The largest flying animal
Aeolian pterosaur is the largest flying animal ever seen on Earth, with an average weight of 250 kilograms and a wingspan of more than 10 meters, living in the middle and late Cretaceous period, flying is simply a "glider"; the largest bird is the ostrich, which is only half the weight of the Aeolian pterosaur, and the ostrich has lost the ability to fly.
The largest non-plant living organism
Aureus melringia is a type of fungus located in the Marul National Forest in Oregon, USA, with a community of Honeyrocketia aureus, covering an area of 9 square kilometers, more than two thousand years old, with an estimated total mass of more than 600 tons.
The largest plant
The General Sherman tree is the largest plant in the world, with a maximum diameter of more than 10 meters, a trunk weight of more than 1,000 tons, and a total weight of more than 2,500 tons; but the tallest tree in the world is australia's almond eucalyptus, with a maximum of 156 meters.
