Nature is beautiful and ruthless. Over the years, more than 5 billion animal species have become extinct, including many ancient creatures that once existed around humans. But it turns out that some of these creatures still live on the same land as humans today. By studying fossils, scientists have discovered that some animals have existed for millions of years. On the other hand, various convincing sightings also show that some creatures that are considered extinct still exist in the world. Through today's article, the editor brought five very ancient animals that are believed to still exist on the earth.
1. Frilled shark
Frilled sharks have been considered extinct for a long time, but in 2007, frilled sharks were found near the coast of Japan. These sharks are most commonly found in Japan's Saru Bay , Their bodies look long and strange, but the heads can tell the characteristics of sharks. Frilled shark is about 2 meters long and has a dark brown body. Frilled shark’s eyes glow in the dark, but its most terrifying place is the teeth, because it has more than 300 trident-shaped teeth, and the teeth are distributed in 25 rows. Frilled sharks have a much larger mouth than ordinary sharks. Nowadays, Frilled Shark is a highly endangered species, and because it has existed on Earth for more than 80 million years, it is considered a living fossil.
2. Mammoth
Mammoths are said to have been extinct about 10,000 years ago, but according to various sightings, many people believe that they are still found in fossils. After all, there are large areas in Siberia that we have not explored yet. And scientifically speaking, there is also the most likely place for mammoths to appear. Mammoths are like huge, furry elephants with tusks. They can reach up to 4 meters in height and weigh up to 8 tons. It is equivalent to the weight of four medium-sized elephants.
Although it is generally believed that mammoths went extinct on the mainland 10,000 years ago,But 4000 years ago, they actually still lived on Wrangel Island in the Arctic Ocean, and in 2012, someone recorded a sighting of a mammoth. In the video, you can see this animal walking in the Siberian river. The photographers didn't get too close to shoot because they didn't want to scare these animals away, and they were worried that their safety would be threatened. Although some people think this is an ordinary elephant, there are no wild elephants in Siberia. Only the corpse of a mammoth has been found in the ice. But whether the mammoth is still alive, there is still a big debate.
3. Nautilus
Nautilus even looks unreal. It is a mollusk that has existed for more than 5 billion years. This creature is a powerful swimmer and can live in the depths of the ocean. This means that predators cannot get close to them, which is part of the reason why they have survived so long on Earth. These animals can be found in tropical waters around the world.
4. White dolphin
White dolphin is a suspected extinct animal, but in recent years, experts believe that this animal may have returned to my country's Yangtze River basin. In 2006, some experts claimed that the baiji was extinct, but only a year later, in 2007, someone took pictures of suspected baiji activities. Experts from the Institute of Aquatic Sciences of the Chinese Academy of Sciences also confirmed that the animal was the baiji. But unfortunately, after that, no one seems to have seen this animal again.
5. Sturgeon
Sturgeon is the oldest member of the bony fish family, they have a history of more than 200 million years, fin sturgeon is very similar to sharks ,The body is very smooth but very hard. The general body length is 18-30 cm, but humans have found many sturgeons that exceed the common length. The largest sturgeon was caught in the Volga River in Russia in 1827, and it is said to weigh thousands of kilograms. But in fact, these sturgeons can also be found in North America.
