Common along the South Carolina coast in the months of August and September, this jellyfish is saucer-shaped, usually brown or red, and 6-8 inches in diameter. Four oral arms and long marginal tentacles hang from the bell and can extend several feet.
Sea nettle stings are considered moderate to severe. This species causes most of the jellyfish stings that occur in South Carolina waters. Exercise caution if sea nettles are observed in the water, and do not swim if large numbers are present.
