The Asian carp threatens the Great Lakes, brown tree snakes are a problem in Guam, Burmese pythons in Florida are all examples of a foreign species invading an area where no natural predators exist.
The latest species to make headlines is one native to California: the albino kingsnake.
Somehow it slithered into Spain's Canary Islands and is now decimating native lizards and geckos. Brian Hinds, president of the California chapter of the North American Field Herping Association, will be traveling to the archipelago as a pied piper of sorts.
