Despite the fact that most living organisms on Earth live peacefully and in perfect harmony with Mother Nature, there are some creatures that are absolute predators and in constant competition with other forms of life. According to most dictionaries, an invasive species is a plant or animal that is not native to a specific location. In other words, an introduced species that has a tendency to spread and is able to cause damage to the environment, the human economy, and human health. Some of these invasive creatures have caused the extinction of whole entire species and have irreparable damage to a surrounding ecosystem. With that said, don't be fooled into thinking that these creatures are scary or even dangerous looking. Some of these creatures were actually kept as pets because they are so cute or even exotic. However, the sad reality is that when introduced into an environment where natural predators where not present, these animals got out of control and completely took over their respective areas.
