Portuguese -man-o-war are most commonly found along bays and beaches during strong onshore winds. They are high in number when winds blow in from the ocean onto land, so beachgoers are urged to observe posted signs. Symptoms of a sting include stinging, burning, redness, swelling of lymph nodes. If stung carefully pick off any visible tentacles. Rinse with fresh or salt water. Apply ice for pain. IMMEDIATE medical attention may be required for severe reactions.
