Secondly, it is difficult to realize them all, because there are too many such monsters, involving religion, local legends, mysterious stories and some real cases that science has not yet explored.

For example, vampires and werewolves are legendary monsters. There are monsters such as Jiao Ren and wild dogs in China legend. Monsters in the Classic of Mountains and Seas abound. These beasts, the nine-headed bird, are said to have been witnessed in Shennongjia. There is also a legend in Yongxinqiao, Beijing. There is a sea beast in the well under the bridge. Because of this legendary well, Beijing Metro Line 2 has indeed changed its route.

There are about 14 kinds that can be found online now:

1, Mongolian dead worm: a blood-red creature that can spit out acidic substances. It is said that it is 5 feet long (about 1.5 meters) and has spikes at both ends of its body. Although Mongolian nomads have reported its existence for centuries, there is no real evidence to prove the authenticity of this creature.

2, long-haired fish: the legendary long-haired fish Trunko, the body is as big as a whale, the whole body has long hair, and there is a "trunk" with a tail like a lobster tail, which moves underwater. This long-haired fish was reported to have appeared in South African waters in 1924.

3. Savage: For centuries, there have been many legends about hairy savage among Australian aborigines. According to legend, this creature is 7 to 8 feet tall (about 2. 1 m to 2.4 m), with bright red eyes and body odor.

4. Zhuobai Cabra: It is a monster that kills livestock and is widely distributed in Puerto Rico, Chile and Mexico. It is said that they will suck the blood of animals. So far, however, no evidence has been found to prove the real existence of this creature.

5. River boy: one of the legendary creatures with a long reputation in Japanese legends. It is said that they look like children, have limbs, are usually very thin, and their skin is sticky and reflective like frog's, leaving traces of mucus where they walk. 1984, a mucus sample left by a suspected river boy was found in a river in Tsushima Island. However, there are too few samples to prove the existence of this animal.

6, snow monster: will attach to the human body. After a period of time, the invaded patient's body will appear frostbitten dark black, and then he will spit out ice cubes, and then he will be extremely eager to eat human flesh.

7.Bradenboro Monster: there are many reports in north Carolina, USA. It is said that a large number of local people have seen this creature, and some even describe it as "round face, glowing eyes and big teeth". Legend has it that this is a heavy creature between a wolf and a bear that sucks animal blood.

8. Dover Demon: Kind of like an alien. They have no hair, their heads are like watermelons and their eyes are orange.

9. Giant Earthworms: There is a giant earthworm subspecies in the forests of South America, called "Minhocao", which means giant earthworm. According to legend, this creature existed in the age of dinosaurs. Most of the reports about the discovery of this creature are in Brazil.

10, Jerona Dwarf: The camper was captured in Spain and lived for a few days after being captured. However, according to Wikipedia, the connection between these photos and the way they reached the media proved that this story about Jerona Dwarf was just an authoritative prank.

Longtu: a legendary creature in Japan. Some people think that this creature is purely based on the fantasy of snakes. However, since the 7th century, the existence of the Earth Dragon has been reported many times, which undoubtedly adds weight to the authenticity of its existence.

12, Rewodang monster: it is a wolf that eats people. They have huge teeth and their tails are longer than ordinary wolves. From 1764 to 1767, it was widely rumored that this creature attacked humans, with more than 200 deaths.

13, Montock Monster: The body found in Montock Beach, new york in 2008, because it was soaked in water for a long time, the whole body was swollen, but it looked like a turtle without a shell, or a raccoon without fur, or a mutant dog. Some people suspect that this is just a scam.

14, striped sea monster: a sea monster with stripes all over its body, and its authenticity is not well documented. In fact, it is somewhat similar to ancient species, such as Nishi or Tianchi Monster and Kanas Lake Monster. Of course, Nishi has been proved to be a fraud.

Other monsters I've heard of:

1. The three monsters of Reiser, France: the glowing stone, the flying chameleon, and the green monster, especially the last one, are like a green carpet that eats people, which is particularly terrible.

2. Humans: the legendary white sea monster looks like a white giant, or like an apostle at the beginning of EVA.

If you are interested in the legendary monsters, you can look at Shan Hai Jing and the ghost night in Japan. Some books on religious legends or folk customs can meet your needs. Generally speaking, your definition of monsters in supernatural legends and eyewitness legends is quite different. The former is the cultural product of a nation or region for thousands of years, while the latter is the culture and myth of a new era created by modern people.
