Giant (Burmese) pythons invade Florida & other southeastern states

In Britain, there is a problem caused by invasive non-native species such as the North American bullfrog, the grey squirrel (grey squirrels were brought to Britain from America in 1876 and they have thrived at the expense of the native red squirrel) the American mink, and the American signal crayfish. They have all made an impact with serious detrimental affect on our native wildlife and habitats which is definitely cause for concern and yet it doesn't seem nearly as bad as the recent news from the USA where giant pythons capable of swallowing a dog and even an alligator are rapidly making south Florida their home, potentially threatening other southeastern states.

It makes me shudder because I have a real phobia about snakes and I noticed this observation : The largest python caught so far in Florida measured five meters (16.4 feet) and weighed 70 kilograms (154 pounds).
