Latest Scourge of NJ Beaches: Man-of-Wars Jersey shore beaches report frequent sightings By Brownie Marie, Newser Staff Posted Jul 6, 2015 12:37 PM CDT 19 comments Comments Fish are seen swimming underneath a Portuguese man-of-war in the Gulf of Mexico, about 35 miles off the coast of Louisiana on March 19, 2011. (AP Photo/Gerald Herbert) (Newser) – Beachgoers spotted a Portuguese man-of-war at a Jersey beach over the weekend, reports NBC New York; this latest sighting in the Garden State occurred on the 26th Street Beach in North Wildwood. Although no one was injured, the increasingly frequent appearance of the potentially deadly invertebrates is disturbing. Two weeks ago, a man-of-war washed up on Harvey Cedars Beach on Long Beach Island, and another was spotted in Ocean City last week. Marine officials say the northeast wind brings plants and animals in from the Gulf Stream, and they warn never to touch the colorful, jellyfish-like creatures. "Their stings are among the most painful, and if somebody is allergic to bee stings or something like that, you can go into shock," a biology professor cautions.
