Chongqing is located in the southwest of China's inland, upstream of the Yangtze River . Chongqing is a unique city. Since the terrain of is gradually lowered from north to south to the Yangtze River valley, the northwest and central areas are mainly hilly and low mountains, and the southeast is backed by two major mountains, Daba Mountain and Wuling Mountain and Wuling Mountain. There are many mountains, accounting for 76%, and it is known as the "mountain city" and " fog " .
is located in the entire Chongqing area, bordering the colorful Guizhou to the south, the mysterious Shennongjia to the east, and the rich Sichuan Basin to the west. It has been famous all over the world for its beautiful natural scenery such as mountains, water, forests, springs, waterfalls, gorges, caves, etc., and has rich natural resources. There are precious plants called "living fossils" such as 海水湖 , Davidia involu , etc., which are known as "living fossils", live here. There are also leopards catching prey in the mountains and forests, golden monkeys sitting elegantly on the trees, and various snakes also appear here.
Recently, a pheasant-necked snake was found here, walking leisurely on the roadside. When the two men saw it, they found it very interesting, so they followed the snake, taking pictures and teasing it. In the end, the snake finally couldn't stand it anymore. Although I was small and not a very poisonous snake, I didn't look down on me like this. I turned my head and attacked the two men, which scared the two men so much that they quickly retreated.
Pheasant neck snake not only looks strange, but also likes to appear in rural toilets.
Pheasant neck snake, scientific name tiger spotted neck slot snake . As it is a strange common name, the snake has a clear neck groove on the back of the neck, and there is a pair of thick black patches on both sides of the pillow. The neck and its distance behind have bright red marks like the cockscomb. When the snake bulges the whole body, it looks more bright, more like the head and neck of the rooster. The ventral surface of the tiger-spotted neck trough snake is pale yellow-green, and the whole body is emerald green or grass-green.
Tiger Neck Slot Snake is a widely distributed Hori family , which is distributed all over the world, and is basically spread throughout the country in my country. You can live freely in cold places such as Tibet and Heilongjiang. The total length of the tiger-spotted neck trough snake is no more than 1 meter, and its weight is only 200~400 grams, and it has many natural enemies. Therefore, the tiger-spotted neck trough snake has also developed the habit of moving quickly to capture prey and avoid danger.
Tiger Neck Slotted Snake's food is very mixed due to its own size and is full of small animals, such as: frogs, tadpoles, , small fish, and sometimes they will also catch birds on the trees and some mice to improve their taste.
Tiger-spotted neck snakes are particularly unsanitary and have many parasites. They like to appear in toilet dung circles in rural areas because these places have various leftovers and are smelly, and there are many mice and insects. Tiger-spotted neck snakes like to eat these small animals, and they don’t have to work too much and can wait for the rabbits, so they often appear. Sometimes people will be frightened to the point of feeding pigs.
It doesn’t hurt you when you eat toads, and you can also absorb toxins.
Tiger-spotted necked trough snake eating toad is not ambiguous at all. Although I know that this toad is poisonous, I am still not afraid at all and can also use the toad's toxins for myself. Look, a toad was resting in the grass in the forest, thinking that no predator would notice it, but he didn't know that a thirsty tiger-spotted neck trough snake was approaching it with a smell. When the toad reacted, he jumped, but unexpectedly he jumped to the mouth of the tiger-spotted neck trough snake.
Toad still wanted to resist, but was bitten by the tiger-spotted neck-trough snake. He could only twist his body symbolically, make a whine sound, waiting for the fate of being swallowed into his stomach. The tiger-spotted necked snake was not in a hurry. When the toad did not resist so violently, he adjusted his position and slowly swallowed the toad from head to tail. He ate it into his stomach without any distress. The whole process was about 10 minutes.
Tiger-spotted necked trough snakes are not always so lucky. Many times the toads learn their lessons and do not leave the shore too far. As soon as the snake approaches, it jumps into the water.Sometimes, snakes will let the prey in their mouths go because the toad is too big. After all, food can be caught again, and if the mouth is cracked, it may not be able to recover.
Of course, the tiger-spotted neck-sloted snake does not just treat it as food, but also absorbs and uses toads to collect it into the special glands on its neck to protect itself. When it sees an enemy, it will shoot out venom from the neck groove on its .
2020, Kyoto University, the Chengdu Institute of Biology, Chinese Academy of Sciences, etc., jointly published an article on this phenomenon. By analyzing the similarity between the secretions of the neck glands of the tabeo-spotted neck trough snake and the toxins in its food, the researchers found that the toxins of the tabeo-spotted neck trough snake are derived from toads in the food.
Tiger-spotted necked trough snake is not non-venomous snake , but an underrated venomous snake.
Previously, the tiger-spotted necked trough snake has always been considered non-toxic or slightly venomous snake because its venom content is very low and people generally die in unison.
But in fact, in addition to having external toxins on the neck, the tiger-spotted neck trough snake also secretes a hematopoietic toxin called Da's gland , which has strong coagulation activity and can continuously activate prothrombin, thereby causing excessive coagulation. The toxicity is even greater than that of most Vipers.
Although the tiger-spotted necked snake has strong intravenous toxicity, it generally does not pose too much danger to people. First, because this snake is timid and basically does not actively attack humans. Second, its fangs are in the throat, and and the venom glands and fangs have no catheters connected to them. The venom is not injected through the venom duct, but enters the wounds of the bitten person through other physical means. So, this is also the reason why many people are bitten by a tiger-spotted neck trough snake and do not show symptoms of poisoning, because they did not give you a harsh mouthful, so that the venom has enough time to seep into the wound.
Conclusion:
Although there are basically no cases of tiger-spotted neck trough snakes in my country, there are also people who have been bitten to death, and some people have died in Japan. Therefore, you should be very careful when contacting tiger-spotted neck trough snakes and not be careless. In fact, this should be true for any snake. Even if you know that the snake is not poisonous, it will not be easy to bite it.
Moreover, these snakes are now at a risk level in our country and are becoming less and less. We should not catch and contact them, but should maintain an appropriate distance, which is beneficial to people and snakes.
