An eel that has invaded america, from Asia I guess. It eats everything and is very difficult to kill. Only known predator in America might be the aligator. One survived for seven months in a damp towel. The experiment was done at some university somewhere.

It is impervious to many poisons and to dynamite. It operates at night. It is a major threat to natural american ecosystems.

I gleaned all of this from the front page of the Wall Street Journal yesterday.
