Jellyfish invading NJ bays, rivers

The jellyfish population in New York and New Jersey is on the rise.

Ecologists say they are migrating their way inland to warmer bays and rivers.

Jersey shore goers are seeing more of the pesky creatures in once-popular recreation spots.

Scientists say jellyfish seek out waterways packed with nitrogen that can come from lawn fertilizer runoff that seeps into the water system through sewers.

Willie deCamp of the ecological group Save Barnegat Bay says the jellyfish population has exploded in New Jersey after first appearing about five years ago.
