Random thought as I sit here in Tucson dreaming of a post-pandemic soak in the Sea of Cortez....


What do we know about those little blue jellyfish that appear along beaches during different months of the year?  From my experience they've always been worst during March/April, but I've also seen them during summer months after a day of a lot of wind/waves.


From memory, they're like a deep shade of blue, seem to almost have a gas-filled sack, and are typically no bigger than a 50 cent piece.  I don't recall ever being stung by one....do they hurt?  A lot?  or is it like a bee sting?  Or less?  


Do they have a particular 'season' or time of year when they are really prevalent?


Just polling the audience here to see what the group knowledge is, hopefully to give us something to talk about non-pandemic related :)

I call them the "Blue Devils", but they are Man'O'Wars. I typically see them in June - July. I have rarely encountered them in March & April. The sting is painful and will leave welts. I bet I have been stung 100 times. lol. Look for a clear bubble on top of the water.

Not a pleasant experience. Snorkeler's are very susceptible as they prowl the surface. Usually getting stung on face, arms, shoulders, and legs. This can cause Anaphylactic shock (caused by allergic reaction), that can be a very serious situation, requiring immediate medical attention.

They seem to concetrate in large numbers in floating seaweed near shore.
Stings on the hands are not that bad but sting welts on your chest and back can last for weeks.
The sting seems to ne more potent during rainy season when the surface sea water pH is lowered slightly
Salty urine will help kill some of he sting as an immediate first aid.
Benydryl is usually prescribed when you get hit bad by several.
Rescate can help.

Yes, those are bad news. Divers learn to use the air from their regulators to clear the surface of them before surfacing.

Man o' Wars - that's what I thought. However, they're so small....I always thought man o' wars could grow much larger. Are there larger ones out deeper, beyond the shoreline?

Thanks for the info :)

Are those the Portuguese ones? Never have seen one here. I think that vinegar is an easy sting treatment. Have used toothpaste. Toughed it out the first time, until I puked, etc. and went for some strong pills. Got it near my crotch the next time and the resulting blue balls was worse than my first shortcomings.

A baking soda paste works even better. Several years ago when coming up after a dive, I got a string of pearls across my face. I keep anti-sting spray on my boat, but it did nothing. When I got to my house, I tried vinegar and my pee, nothing helped. Finally, a friend suggested a baking soda paste and that worked very quickly. I had a mark for more than a week from that devil.

Not sure if it was said, but first carefully peel and scrape away. Don't rub in the venom sacks!

For best results first do like Bryan said in post #10.  Then make a paste with vinegar and Adolphs Meat Tenderizer (use the original version that lists papain as an ingredient).  Allow to dry and and fall off.  Repeat if necessary.  Also effective for spider bites.
