Wildlife officials working to eliminate the "snakehead" fish apply a final batch of the poison "Rotenone" to a pond in Crofton, Maryland, near Washington, September 4, 2002. To the surprise of state officials, no snakeheads have died in this pond over the past two weeks since they started dumping herbicides to kill plant life and cut off oxygen. Snakeheads grow up to three feet long and can slither across land for several days in search of prey. Native to China, they have a voracious appetite, eating other fish, frogs, small birds and even their own young. The snakeheads were dumped into the pond by a resident who bought them from a New York market to make soup for a sick relative. The relative got better, but the greedy fish had become too expensive to feed. In their new habitat, they reproduced quickly and 100 baby snakeheads have been found.
