Among the many visitors to the South Fork this summer is a dangerous multicellular organism making an appearance along the shore.
The Portuguese man-of-war, a highly toxic warm-water creature that resembles and acts like a jellyfish, has been spotted over the past few weeks on Gibson Beach in Sagaponack, Georgica Beach in East Hampton Village, Indian Wells and Atlantic Avenue Beaches in Amagansett, and South Edison and Ditch Plain Beaches in Montauk.
