FISHZILLA.

The Harlem Meer, in the northeastern corner of Central Park, has long been a refuge for city people looking to indulge their inner Huck Finns, whiling away a lazy summer afternoon fishing for bass, yellow perch and black crappies.

But late last week, signs started popping up around the lake notifying anglers of the arrival of an intruder. The dreaded northern snakehead, a fierce predator common in the rivers and lakes of Asia but considered an invasive species in American waters, had been spotted.

The warning to anglers was clear: If you catch this fish, do not release it. Contact the authorities immediately. It does not belong and could radically alter the local fish population.

The snakehead is a relentless and efficient predator that devours just about everything in its path — fish, frogs, crayfish, beetles and aquatic insects. And it does not meet death easily; it is able to survive under ice or live on land for days in damp conditions. It has been called Fishzilla. (via)
