There are two famous Snake Island in the world, where different snake species live, and the fate of snakes on each island is different.

01 Dalian Snake Island : Half a year of predation, half a year of sleep

Dalian Snake Island is located in the Bohai Sea in the northwest of , Lushunkou District, 7 nautical miles away from the nearest land. The entire island is 1,500 meters long and 800 meters wide, with a total area of ​​1.2 square kilometers. In this small land, there are more than 20,000 snakes living: the black-eyed viper.

Dalian Snake Island's living environment is extremely harsh. Apart from more than 200 plants, there is almost nothing on the island, and even fresh water is extremely lacking. This has led to almost all the animals on the island's island's death, leaving only the black-browed viper to survive.

So, what did the black-eyed viper survive?

first, extremely tenacious vitality. The black-eyed viper can survive as long as he preys a few times a year;

second, eat for half a year and sleep for half a year. In spring and autumn, migratory birds breed on the island, and the black-browed viper takes the opportunity to catch more birds to eat. In winter and summer, the black-browed viper spends hunger years through hibernation and summer hibernation.

Now, the black-browed viper on Dalian Snake Island is protected by humans, and even the mice that eat snakes during hibernation have humans to help them eliminate them.

02 Brazilian Snake Island: One step a snake.

Brazil Snake Island is located on the sea surface 35 kilometers away from the coast of Sao Paulo, Brazil. It covers an area of ​​only 0.43 square kilometers. The island is narrow and long and has a relatively flat terrain. There are about 4,000 snakes on the island, most of which are golden spearhead vipers.

Golden Spearhead Viper is a highly venomous snake species. The venom can dissolve human skin and eventually lead to death. However, the snake venom of the Golden Spearhead Viper has many medicinal values. Therefore, the price of a Golden Spearhead Viper in the black market is as high as US$10,000-30,000.

However, although many poachers risk their lives to hunt on the island, 90% of people die from the mouth of poisonous snakes. So much so that the government announced a ban: no one except scientists are allowed to go to the island.

Because of this, the golden spearhead viper has the opportunity to reproduce and survive and live happily on the Brazilian Snake Island.
