According to the US National Geographic website, according to a report released this week by the US Geological Survey, if the world's largest snake, green water python, is settled in the United States, they will become one of 9 giant foreign snake species that may cause panic.
Scientists from the geological survey evaluated the dangers of 9 alien boa constrictor invading the United States, where the risk of invasion by pythons was most likely to occur in areas where pet snakes were usually released into the wild. The report points out that the green water Python is one of 4 species of boa constrictor that is moderately dangerous. This Python is not a popular pet, and it is less than 500 annually brought to the United States. Although green water pythons have been found in the wild, there is no evidence that they have bred the next generation.
The 5 pythons shown in the picture are real big guys. Apart from them, geo scientists also studied 4 other similar boa constrictor, including South African python, DeSchauensee anaconda, python bananas and anaconda.
Kenneth Krisko, a senior zoologist at the natural history museum in Gainesville, said the report was "complete and thorough". "It is not surprising that pythons can potentially pose a threat to wildlife and humans," he said.

The photo shows a green anaconda, photographed in the Amazon River Basin. They can reach 23 feet (7 meters) and weigh 550 pounds (about 227 kilograms). This olive green reptile can thrive in the peninsular Peninsula and southern part of the state because the local climate is similar to that of the green water Python in South America.
Although the green boa is not known for attacking humans, their food is also very extensive, including fish, turtles, dogs and tulas. The boa constrictor will lie in the water to attack prey and crush the prey with the lethal power that can crush the bones.
2. Tiger Striped Python
The photo was taken in June 13, 2009 at the National Geographic Explorer camp in Scottsdale, Arizona. In the photo, Brady Barr, the host of the TV program dangerous encounter, is playing with a 18 foot (5.5 metre) Tiger Print python. His expression is very relaxed. A group of children are surrounded by him.
But we must not think that Tiger Striped Python is a mild animal. The boa constrictor has a body length of up to 32 feet (10 meters). In its native Southeast Asia, they are well known for their tragedy of attacking human beings and causing death. According to the geological survey report, Tiger Striped netted pythons are the most dangerous snakes to humans.
The longest boa constrictor may have a moderate risk of settling down in the United States, the report said. Tiger Striped netted python, with its skin color and beautiful mesh, is one of the highest number of pet snakes introduced in the United States. The tropical habitat of Nan Kok will be the ideal place for the reticulated python to get its own body.
"People here are not used to preventing large snakes," said Christian, a museum of natural history.Usually, the proposal to avoid being attacked by crocodiles is far away from the high grass along the river bank, but this proposal is obviously not effective in avoiding attacks by exotic snakes. They can climb far away and are very fast and are likely to attack humans. "
3. Python

In this unmarked photo, Skip Snow of the National Park Service is measuring a python captured at the center for research and development. The boa constrictor, native to South Asia, looks bright and easy to manage. It is the mainstay of the pet snake market, especially when the pet snake is accidentally and sometimes purposefully released into the wild. The report says tens of thousands of pythons live in Python, and some of them are rare dishes such as guinea pig and rout.
The government did not take enough measures to contain pythons, partly because the reptiles were more common in public and private areas, he said. "Pythons cannot see the political boundaries. We need to take measures to get rid of them and slaughter them. "
4. rock python

Rock pythons are the largest snake species in Africa. They are temperamental and can reach 20 feet (about 6.1 meters) in length. The US Geological Survey reported that this Python has recently been thriving. "The risk of African pythons is higher than that of pythons," he said. "They are so fierce and terrible that they have been shown from the moment of shell breaking. For this reason, this boa constrictor, originally from sub Saharan Africa, has not become an American favorite animal.
The picture shows an adult African python, which is eating a little impala. The report pointed out that if released to the peninsula, South Texas, and Puerto Rico and other areas, the African rock python can be settled very high.
5. king snake

The picture shows a king snake found in a county park in southeast of Shandong Province.According to the US geological survey report, with surprising environmental adaptability, it is easy for the king snake to open up their colonies in most parts of the southern United States. The boa constrictor, native to central and South America, is usually kept as pets by Americans. If they have the chance, they will most likely settle down in the United States. According to the current situation, the escaped king snake has bred the next generation, but the report also points out that the king snake never attacks humans.
