Messing with Mother Nature: Snakeheads

Fish normally are found in three places: in the wild water, in aquariums, and on our dinner plates. But fish can move from one of these worlds to another. Fish imported to eat or to keep as pets sometimes get into the local ecosystem, which is not their native habitat. The population controls of the species’ native environment might not be present in the new place, or they may take over another species’ spot in the food chain. That’s pretty much the story of the snakehead fish. Read the whole thing in an article I wrote for mental_floss.
