Yahoo! News - Maryland Poisons Pond to Kill Predator Snakefish

Maryland state game officials sprayed enough poison to kill every fish in a murky pond Wednesday to get rid of a foreign predator that had infiltrated suburban Washington: the voracious, land-crawling snakehead fish.

They killed all the fish to protect them from the predator snakehead fish. That makes sense.

(I understand why they did this but I just thought the headline was funny.)
