Portuguese Man-of-War

Look like a familiar beach scene? The Portuguese man-of-war (Physalia physalis) is not actually a jellyfish, but a colony of organisms living together. Please be careful if you find one for even if they are dead they can sting you. Have you seen any on the beach so far this summer?
