Beachgoers this weekend in east coast U.S. in Jersey Shore should beware of a horde of jellyfish-like creatures where they can painfully sting unknowing victims. However, this is not just your regular garden variety jellyfish as these creatures are one of the most poisonous marine species in the world.

The deadly Portuguese man-of-war has been seen across the New Jersey coast where more of the seemingly colorful creatures are likely on their way to the beaches even if these exotic marine animals are mostly spotted in tropical regions.

According to Paul Bologna who is the director of marine biology at Montclair State University, he searched the Island Beach State Park in Ocean County with his students to study and test this man-of-war that is usually tinged with neon blue and purple hues.

Although the students did not find one immediately, Bologna says that it does not mean that it's not there. There are apparently more than a dozen sightings along the New Jersey coast this summer. 

Northeastern winds including the Gulf Stream that are originating from the south are most likely causing this wave of man-of-wars that drifted from Florida and the Carribean. Bologna believes that these poisonous sea creatures will most likely target Cape Cod and Martha's Vineyard located in Massachusetts next, but they will also seem to float around like bloated pieces of plastic on top of the New Jersey water for a few more weeks. 

The first reports of man-of-war sightings were in New Jersey at Harvey Cedars Beach located in Ocean County. Beach patrol posted warnings on Facebook stating that it's safer to swim near a lifeguard and be aware of the surrounding waters while swimming or near the shore.

According to the National Oceanic and Atmospheric Administration, these man-of-wars can be extremely toxic where their sting can cause intense pain, welting and blistering when victims fall into prey with their tentacles which can measure up to 30 feet under the water.

Bologna also describes victims as usually not seeing these creatures on the shore where they are most likely to step on them since they are translucent and can blend with the water, making them almost invisible. The pain can be described as most excruciating since they excrete seven types of toxins that can cause death to those who are prone to allergic reactions.

If someone steps or have an unfortunate encounter with the man-of-war, they should immediately douse the sting with water or vinegar and seek medical help. Urinating on the sting will not help, as this is an old wives' tale, says Bologna.
