HARVEY CEDARS - Jellyfish have long been a stinging fact of life at the Jersey shore, but lately some dangerous species have been making their way to the area.
Lifeguards in Harvey Cedars on Long Beach Island discovered a Portuguese man o' war on Sunday.
It packs a dangerous, painful sting that in some instances can be life-threatening. It also has tentacles that can grow as long as 30 feet, and is usually found in warmer waters.
The National Oceanographic and Atmospheric Administration says a Portuguese man o' war is highly toxic and packs "an intense sting."
Painful box jellyfish also were found in Ocean County last fall.
Montclair State University professor Paul Bologna says both species probably rode Gulf Stream currents up from Florida, where they are common.
