Do you know what animals have the longest neck? You'll probably say giraffes, but I'm sorry to tell you that it's not giraffes. Today, Meichun will take you to understand the ten kinds of animals with the longest necks on the earth, especially the last one, which is likely to be beyond your understanding.
Tenth place, ostrich. Ostriches are the largest bird in the world. Ostriches can reach a height of 2.5 meters and a weight of 150 kilograms when they reach adulthood. Ostriches have a neck like a snake, with a slender neck about a meter long. Although the ostrich cannot fly, it has muscular thighs and can run at speeds of up to 70 kilometers per hour.
In the ninth place, the alpaca, you may not expect the alpaca's neck to be about 1.2 meters long. Alpacas look like sheep, but they do not belong to sheep, but belong to the camel family. Alpacas first originated in North America, where they were domesticated by humans between 5,000 and 6,000 years ago.
Now, they live mainly on the plateaus around the Andes in South America, with alpacas eating mainly the thorny food of the mountains. In recent years, alpacas have become popular on the Internet. They have a cute appearance, but they have a special hobby, that is, they like to spit on people, which makes people love and hate alpacas.
In the eighth place, the giraffe, the giraffe is undoubtedly the longest surviving animal with the longest neck on earth. Giraffes can stand up to six to eight meters tall from head to toe. The neck alone occupies about 2.4 meters, the body length is four meters, and the maximum weight can reach 1930 kg. The newborn cubs are 1.5 meters tall. The top of the head has a pair of short horns covered with fur, which was called a unicorn during the Ming Dynasty and lived mainly in Africa. Giraffes sleep on their feet, sleeping only five to ten minutes at a time, and sleeping up to 20 minutes a day.
Because the giraffe's neck is too long, it cannot feed on grass as the main food, and can only use leaves as the staple food. Because giraffes are so tall, their blood pressure is also higher than that of ordinary animals, because only then can the heart deliver blood to the brain at a higher place. Giraffes have about three times as much blood pressure as adults, so when they lower their heads, the valves behind their ears regulate their blood pressure and prevent them from going too high.
The seventh, the ancient rhinoceros, is an extinct rhinoceros that lived in the Oligocene more than 30 million years ago. They are up to six meters tall, with a neck length of 2.5 meters. Usually, they feed with fang-like upper jaw teeth. It is also the largest known land mammal.
Sixth, Plesiosaur, Plesiosaur was a terrifying predator who lived during the Triassic period. It became extinct for some reason during the Cretaceous Period, and during the Jurassic period it spread across the world's oceans. According to fossil studies of plesiosaurs, plesiosaurs were very large and should have been the overlords of the oceans at that time.
They can reach a length of up to 14 meters, and the neck alone occupies about 7 meters of the entire body. Their limbs had fleshy unicorn feet suitable for paddling, so that plesiosaurs could not only move freely in the water, but also climb ashore to rest. Plesiosaurs had a conical shape between their teeth and were slightly curved.
The fifth, Diplodocus, lived in western North America at the end of the Jurassic period and dates back 150 million to 147 million years. They are more than 30 meters in size, weigh about 10 tons, and have a neck length of 7.5 meters. His nostrils are above his eyes, the front teeth of his mouth are flattened, and the sides and rear end of his mouth are toothless. So they almost never chew when they eat, but directly swallow food such as leaves.
The fourth, Brachiosaurus, lived in North America during the late Jurassic period. They are 26 meters long, weigh more than 30 tons, and the neck length of wanlong reaches 9 meters. And the brachiosaurs' teeth were large and flat, like spoons, with sharp edges, and biting off branches was a breeze for them.
Brachiosaurus did not eat leaves as gently as other animals, but crudely ate leaves and small branches into their mouths. On average, they eat more than a ton of food a day. Brachiosaurus has a gentle personality and prefers to live in groups. To satisfy their appetite, they also need to migrate in droves. Everywhere they went, the ground shook, smoke billowed out, and all kinds of small animals fled in all directions. Only pterosaurs and Archaeopteryx in the sky hovered leisurely around him.
The third place, Poseidonosaurus, was the first giant herbivorous dinosaur found in the United States in North America. It lived in the early Cretaceous period, 112 million years ago. It can reach 30 to 34 meters in length, weighs 50 to 60 tons, has a neck length of 12 meters, and their first cervical vertebrae are up to 1.5 meters long.
The second, the Argentinosaurus, lived in the middle of the Cretaceous Period, 100 million years ago. A herbivorous dinosaur that emerged on the South American continent. According to the analysis, they can weigh about 90 tons, which is quite huge. Stepping on it can even make you merge directly with the ground. Moreover, their bodies are 35 meters to 40 meters long, and the length of their necks alone is about 13 meters, which is equivalent to the height of 4 floors.
The first place, Mamen Xilong, Mamen Xi dragon lived 150 million years ago. The muscles around their necks are quite strong, supporting its small snake-like head. In 1987, a joint expedition of paleontologists from China and Canada found the largest fossil of Mamenxi dragon, named Zhongjia Mamenxi dragon.
His fossils were significantly larger than those of other Mamenxi dragons. The body length of the Chinese-Canadian Mamen Creek Dragon is 35 meters and the weight is expected to be between 60 and 80 tons, equivalent to the total weight of more than 30 elephants. In addition, its vertebrae are up to 1.6 meters long, and the total length of their necks is estimated to be at least 15 meters or more, which is a well-deserved Giant.
At that time, several dinosaurs with necks similar to those of Lepidolus and Brachiosaurus were found, but their specific fossils may be incomplete, so there is no accurate data.
That's the end of the video. I am the omniscient Miharu, and like my video of the old iron to follow a wave of comment area discussions that everyone has to say. Thank you for your support, we will not see each other in the next issue.
