These ugly creatures can deliver a very painful sting.   They move by a combination of winds, tides and currents, all of which can drive them to the ocean's beaches.  The experts say Man o' war rarely are alone, and if one is found in a certain area, there are most likely more.

And what is even more creepy about these sea creatures is their tentacles that are about 30 feet in length but can be up to 160 feet.   The tentacles can paralyze small fish and can cause severe pain to humans.

In the past few days there have been sightings of Portuguese Man o' wars at Horseneck Beach and at Fort Phoenix.   Those reports have not been confirmed by the sate Department of Conservation and Recreation however.  But they are still warning beach goers to be careful and be on the lookout for man o' wars on the beach and in the water.
