If you go down to the woods today, you're in for a big surprise! So stay in and read about the nasties you'll find there: from North America's grizzly bears to Europe's wolves. In Africa, stay clear of the black mamba's 'kiss of death' and in South America's rainforests keep out of the path of Brazilian wandering spider. It's no safer downunder in Australia, where huge saltwater crocs lurk just beneath the water, or in Asia, where you need to watch out for big cats!
