Burmese pythons are native to Southeast Asia, but in the last 40 years, they've invaded the Florida Everglades, where their population has exploded. This short comic explains how Burmese pythons got there in the first place — and how it's wreaking havoc on the ecosystem.
Think that a snake can't follow you into the next room because you've shut the door? Think again. Julius, an albino Burmese python, figured out how to work her body onto door handles and get those suckers open.
Pythons have made some terrifying surprise appearances in Florida. On Christmas day, for example, a Miami family found a 13-footer in their swimming pool.
Not all invasions come from marauding armies. You can devastate a place just by introducing a non-native species that creates dramatic and unexpected shifts in the dynamics of the ecosystem.
