Harvey Cedars, N.J. — 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-of-war on Sunday. The National Oceanographic and Atmospheric Administration says it is highly toxic and packs “an intense sting.” The painful sting can in some instances can be life threatening. The man-of-war also has tentacles that can grow as long as 30 feet and is usually found in warmer waters.

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.
