Which marine hydrozoan is in the picture?

Almost ran into one while snorkeling, saw the beaded strings hanging down so was able to avoid it.😮

The best antidote for many marine poisons is heat. Any decent heat source (hot sand helps) will do but best is to immerse the affected area in water as hot as you can stand and the toxin is destroyed quickly along with the pain. I don't understand why life guards don't know this. This is all from personal experience as a surfer, having been stung many times by blue bottles and once badly by a stingray - it works.

Fell into a pod of them in Corpus when I was 11, thought I was gonna die! 5 days in the hospital - worst vacation ever!

Very interesting; thanks for the detailed information!

ColonelSwak, I had heard that vinegar also helps kill the sting.

My Sister was stung by one when we were in Hawaii
