Speaking of snake island, we also have a well-known snake island at home and abroad in China - Dalian Snake Island, but when it comes to the degree of terror, Brazilian Snake Island is more recognized by scholars or experts at home and abroad, known as "the world's most terrifying snake island", let's take a look at the Brazilian snake island together, and Dalian Snake Island to do comparison.
1. Comparison of the area of the island and the number of poisonous snakes: The Brazilian snake island is the great Kaimada Island, 35 kilometers from the southern coast of the Brazilian state of São Paulo, with an area of only about 0.43 square kilometers. Dalian Snake Island in mainland China, which we have specially introduced in the previous article, covers an area of about 1.2 square kilometers, which is about 3 times that of Brazil Snake Island.
The terrain of the two snake islands is similar, both are very narrow and long, but the terrain is different, Dalian Snake Island is dominated by cliffs and cliffs, and Brazil Snake Island is relatively flat.
Dalian Snake Island, cliffs and cliffs can be seen everywhere
Brazil Snake Island, the terrain as a whole is relatively flat
From the topographic point of view, Dalian Snake Island has many cliffs and cliffs, so it will not encounter snakes in many places on Dalian Snake Island, and the poisonous snakes on the island are mostly concentrated in the central region. The Brazilian snake island as a whole is relatively flat, and the probability of encountering snakes after landing is much greater, so the Brazilian snake island is more dangerous.
2. The number of venomous snakes and the types of venomous snakes: Dalian Snake Island is a black-browed pit viper, the number of venomous snakes is very single, the number of about 20,000, because the space suitable for snakes to survive is limited, in Dalian Snake Island often see the same branch hanging 2-3 snakes.
Hunt together
All waiting for migratory birds
There are about 4,000 poisonous snakes on the Brazilian snake island, most of which are golden spearhead pit vipers, which is the smallest snake in the spearhead pit viper, generally less than 1m in length, but the venom is among the best.
Therefore, from the perspective of snake density, the snake population of Dalian Snake Island is larger, but there are no poisonous snakes in most of the area on the edge of Dalian Snake Island, because they are basically cliffs and cliffs, and most of the poisonous snakes are concentrated in wooded places. The venomous snakes on the Brazilian snake island are evenly distributed, basically encountering 1-3 venomous snakes per square meter. The risk factor is still more dangerous than the Brazilian snake island.

3. Hunting method: The bird catching skills of the golden spearhead viper are higher than those of the black-browed pit viper, and the black-browed pit viper is generally hunted in the way of waiting for the birds in the branches, generally choosing a good place after a day without moving, they are very patient, must wait until the birds enter the attack range and then attack.
Motionless waiting for the birds to come to the door
When the black-browed pit viper catches migratory birds, it chooses to fall from branches to the ground with migratory birds or throw dead prey to the ground and eat, in order to use the friction between the prey and the ground to speed up the devouring speed. In general, if they can catch 3-4 migratory birds in a year, they have enough energy to reproduce.

The golden spearhead pit viper is more flexible in its hunting method, first using thermal sensors to detect the location of migratory birds, lurking in the branches closer to them, and finally using their tails, they will swing the slender back and forth or bend to simulate the movements of worms to attract birds.
Use the tail
Simulates bug squirming
Therefore, the poisonous snake hunting skills of Brazil Snake Island are higher than those of Dalian Snake Island.
4. Venomous snake toxicity: The black-browed pit viper venom of Dalian Snake Island is not outstanding in the venomous snake ranking, and it is much worse than the cobra and the silver ring snake and the white-browed pit viper, and the snake venom is mainly a blood circulation toxin. Mainly to make the wound bleeding, hemolysis, etc., of course, serious will lead to systemic bleeding and death. Data show that the semi-lethal amount (LD50) of the black-browed pit viper is 0.813mg/Kg, the silver-ringed snake is 0.08mg/Kg, the Zhoushan cobra is 0.34mg/Kg, and the white-browed pit viper is 0.15mg/Kg, so the virulence of the black-browed pit viper is not outstanding.
In order to adapt to life on Snake Island, the golden spearhead pit viper on the Brazilian snake island is 5 times more toxic than the South American mainland's close relatives, the spearhead viper, because the prey they catch is basically migratory birds, in order to prevent migratory birds from biting and flying away, they have evolved super venom. The venom of the golden spearhead viper is also very corrosive, can dissolve our flesh, the venom is rich in neurotoxins and blood circulation toxins, generally after biting people, it will cause death within 1 hour.
In terms of toxicity, the Golden Spearhead Pit viper on the Brazilian Snake Island is more virulent.
5. Brazil Snake Island has a very famous local legend, it is said that from 1909, there is an island keeper who landed on Snake Island and began to guard the island, reminding strangers not to board the island and avoid being bitten by poisonous snakes. During the 11 years that the island keepers lived on the island, the island keepers worked hard, and together with their wives and daughters, they reminded countless passers-by of the passing boats and passers-by, and their families had long been accustomed to life on the island, everything seemed calm and stable, but the accident quietly arrived one night.
The Brazilian government built modern lighthouses, managed by the military
That night, the venomous snake may have followed the prey to the home of the island keeper, who was unfortunately bitten, and his wife and daughter were also bitten by the poisonous snake during the escape, and no one has seen them since then, which also casts a mysterious atmosphere on the snake island.
Later, the Brazilian government built a modern lighthouse to show the fishermen at sea, which was usually managed by the Brazilian army. At present, the Brazilian government has ordered that outsiders are prohibited from landing on the island, and unless there is a special permission to scientists or scholars, the island landing will be severely punished by local law.
However, because the venom of the golden spearhead viper has very high research and medicinal value, it is in short supply on the black market, so many poachers will venture to the island to find the golden spearhead viper, it is said that the current price of the golden spearhead viper is as high as 30,000 US dollars, which can be said to be very expensive. Of course, at present, because of the scarcity of the golden spearhead viper, it is strictly protected by local laws.
Brazil Snake Island is currently recognized as the most dangerous area, for Xiaobian, whether it is Brazilian Snake Island or Dalian Snake Island on the mainland, it is a forbidden place. I also hope that these snake islands can continue to multiply, so that our descendants can also understand these magical areas, love nature, and everyone has a responsibility.
