The brown tree snake is a species of snake native to Papua New Guinea, eastern Indonesia, and the Solomon Islands that has become an invasive species on Guam.
A non-native species that causes harm to the environment into which it has been introduced. Like our party crasher, these are organisms that disrupt their new environments.
The variety of life in a particular habitat or ecosystem. It's like having a diverse guest list at a party - until someone uninvited shows up and starts causing trouble.
The state where all members of a particular species have died out. It's like if our party crasher scared off certain guests so badly they never attended another party again.
