The animal kingdom is a strange place filled with the weird creatures. There's no doubt that some of us have looked at an animal and thought it was the weirdest looking thing you've ever seen. Until now.

Planet Earth is filled with billions of creatures. Some cute, some nice, some strange looking, and some deadly. Some of these animals kill hundreds of people every year. Others have powerful venom that can kill within a few hours. Still others have such a painful sting/bite that you may wish that you were dead.

Dinosaurs have been a fascination of children and adults alike for generations. Dinosaurs surged in popularity following the film Jurassic Park and its sequels. It's just a damn shame that they went extinct 65 million years ago. If they had survived to this day, there would certainly be some that would be kept as pets.

Our planet is home to many different forms of life, from plants to animals to bacteria. However, human beings have been the only species to fully manipulate and control their environment. Lurking in the shadows, though, are five species that are looking to take over man's place as the top species. These "fearsome five" all have the capabilities to take over the world. If you ever have that feeling that you are being watched, it's because one of these species is doing surveillance on you.
