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

Bluebottles, or Portuguese man o' war, sting as a defense mechanism and to capture prey.

This venom can cause pain and irritation, deterring predators and helping the organism immobilize small fish and plankton. The sting serves both protective and predatory purposes in their survival.
