Here is a no mammals, no water, no long-term living bird island; here has taken every step to be cautious, because there live thousands of poisonous snakes. In Brazil Ilha da Queimada Grande is known as Snake Island, the reporter and biologists began a adventure.

"Yes, on the island all snakes are poisonous," snake Institute biologist Karina Bunch told Xinhua News Agency reporters, "They are islands spearhead viper, so here is called Global one of the most dangerous areas. "

Big queimada island from the south coast of Sao Paulo state about 35 kilometers, an area of ​​04,300 square kilometers, 1984 by the Brazilian federal government to establish a nature reserve, any unauthorized person can not landing. Recently, after Brazil won the approval of the federal government under the Chico Mendes Foundation, the Xinhua News Agency reporters Deng Dao and Yi Qiyu snake Institute biologists.

Landing is not easy, though only 35 km from the coast, but have to wait until calm day before the sea. Due to the large island queimada no beach, only use the boat landing personnel to the rocks, and then stepping on the bodies of shellfish climb up on the rocks.

Due to inaccessible island and there is no way, the researchers had to step out of the road was soon covered with dense vegetation. To avoid the chance encounter with the snake, experts Chico Mendes Foundation is responsible for leading the way, they follow the previous mark to lead us forward in many places has long been blocked by tree branches branches spread, we need to re-open with machetes.

After exploring nearly an hour, a pedestrian did not find a snake. Bunch explained that the snake-like moisture, relatively dry in recent days, it is hard to see them. Sure enough, relatively moist areas, Bunch found on the low branches of a snake, the snake is very similar to the color of the branches, only experienced researchers to recognize.

Before landing, Butan Tan Snake Institute of Museum Giuseppe briefed reporters on Porto different on the big island queimada spearhead viper and the mainland, they are birds for food, so come and go during the day the total stay in the trees; and spearhead viper usually haunt the night on the mainland, on the ground activities, prey rodents.

Porto said that, because of the island's food is the spearhead viper birds, toxicity must be very large in order for the attack soon after the poisoning of birds whereabouts, or bird flew away, and their relation to the hungry.

Do not look poisonous snake, the researchers arrest Shique no tension, deft movements. After the discovery snake, Bunch rapidly with a large clip snake caught, and select the appropriate according to the thickness of the transparent tube, the inner tube is introduced snake, left half body outer tube.

"After the snake caught, we first look at whether there had implanted chip, the chip is equivalent to their 'identity', a record of all the data on time. No matter whether the chip, we have to tailor-long snake, measuring body temperature, weighed, found records of the time, place, and then a small skin sample will be brought back to the laboratory for DNA analysis, will gather some of the semen of the male, the female will touch the abdomen to see if pregnant, "Bunch side and assistant to measure, record, while the interpreter to reporters.

For the snake had been implanted with a microchip, the experts will compare old and new data, and the newly captured snakes were implanted with a microchip. After the study is completed, they will snake into the bag, then the bag to get the release finds its place.

In the next two hours, they found a pedestrian total of six snakes, some entrenched in the trunk, and some hid behind a rock, for inexperienced reporters, it was found that they do not say is that the expert refers to we shall narrowly look upon a long time to find, but experts generally when measuring a snake is not over yet discovered another one.

The 7 snake was found only one had previously been implanted chip, Bunch said:. "This is a good thing, because we have a chance to study more Butan Tan Snake Snake Research Institute in Grand Island queimada been breeding snakes, study the evolution of other projects, but generally speaking, a variety of snakes mastery of information is still very small. "

For snakes research will eventually be the service of mankind. Butan Tan Snake Serum Institute, mainly through the acquisition of snakes, poison the manufacture of drugs to overcome. Currently, Butan Tan annual production of nearly 200 million vaccine and 1 million anti-venom serum, can save 80% of the Brazilian people are bitten by venomous snakes. Some venom molecules may also help lower blood pressure, for the manufacture of a medicament to alleviate angina.
