Yes they have stingers like jelly fish. Few portuguese man-of-war (blue- bottles) stings in Hawaii cause life-threatening reactions, but this is always a possibility. Some people are extremely sensitive to the venom; a few have allergic reactions. Consider even the slightest breathing difficulty, or altered level of consciousness, a medical emergency. If tentacals are stuck in skin do not apply vinagar. This may cause a worse reaction. Rinse with water until gone. For more informatio visit:http://www.aloha.com/~lifeguards/portugue.html
