Australia's unique plants and animals are one of the many reasons people visit this country. Australia has more than 27,700 plant, 378 mammal, 828 bird, 4000 fish, 300 lizard, 140 snake, two crocodile, and around 50 marine mammal species. However, Australia is also home to some of the most dangerous plants and animals in the world. Australia's deadliest animals often make the top lists owing to a combination of their venom and defensiveness, as well as their proximity to populated areas. On the face of it, plants may seem innocuous, but about 1000 species of plants in Australia are known to be toxic to animals and humans, and plenty more cause skin and eye irritation, rashes or discomfort. Don't wander around Down Under without learning about the 50 most dangerous, deadly and downright dastardly creatures that live here, from the scariest snakes and injury-causing insects to blood-curdling birds. With animal fact-files, location information and more, Killer Oz is the perfect guide to deadly Australia.
