Jellyfish Everywhere

I went scuba diving off Hollywood Florida beach November 20, 2013 and saw moon jellyfish of all sizes. I went out about 300 feet from shore and felt burning and turned on the lights to look around. The moon jellyfish were from about 4 to 12 inches in diameter and they were everywhere. I was feeling a burning on my legs and had to cancel the dive. The ocean was very calm and the moon was full, if not for the jellyfish it would have been the perfect night for a dive. The jellyfish were about every 3-4 feet in all directions.
