Greetings,
Mr. m. Thanks for that. One thing in the link puzzled me. " You can also drive them away by shuffling your feet in the water as you walk." Hmmm...Not sure how that would work.

It won't.
This from someone whose whole family got whacked - mostly right behind the knee as we backstroked to the boat, by these things.

That is usually the recommendation for how to avoid being hit by a Sting Ray.

Yup, rays hug the sand. These floating feckers, well, they float! And getting banged by one right behind the knee is an experience you do not want to have.
Whimper? I was a basket case!

I got hit by a jellyfish on the back of the leg, including the back of the knee, over 20 years ago...I still remember it vividly.

The jellies here come out in summer. Nasty buggers. Got hit on the neck while diving - not fun

If unlucky enough to get stung, wash liberally with white vinegar, big bottle of it is standard equipment in summer over here.

Then apply cortisone cream, a must have on board.

Shuffling feet is good advice to avoid sting rays in the shallows. Especially in the Summer when they come out of the deeper water looking for warmer temps. I have been stung 3 times and those little guys things pack quite a punch. If you get stung by a ray -hot water. Pee is an old wifes tale, at least for Rays.

I was swimming in the surf on Cumberland Island, GA two years ago. All the doctors can figure is I got into an area filled with microscopic sized jellyfish. I was a giant welt on my entire body except above my neck and head. It took a month's worth of high powered prednisone to deal with it. It as misery. I'm from Florida. I thought I knew what a jellyfish looked like. I have since discovered that they come in all sizes.

Each jellyfish tentacle is covered with thousands of stinging cells with syringe-like body parts called nematocysts - if you like medical jargon - which live along the length of the animal's tentacles and fire venom. The venom is a neurotoxin designed to paralyze jellyfish prey.
Too numerous species of jellyfish therefore I am not intended to provide any particular advice. However a few things may help lessen the pain of jellyfish stings:
Do not rinse the skin with sea water or fresh water. Water brings just a soft neurological sensation which has nothing to do with denaturing the venom. Also water can worsen the symptoms.
Apply vinegar, this had been shown to prevent further venom release by allowing the tentacles (if some) and stinging cells to be safely removed. Also vinegar may help to partially inactivate the venom for most of jellyfish stings.
Carefully shave the skin with the edge of a credit card or ID card to eliminate most of the stinging cells.
Apply a corticosteroid cream (if no allergies, intolerance or other related medical issues to cortisone or hydrocortisone).
Seek medical attention particulary before taking any topical medication.

We always have a gallon on board - mostly for the head hoses.

Greetings,
A question for the "medicos" or those in the know...What are the chances of anaphylactic shock? Would it be prudent to put an epi-pen in the medical kit or are there OTC medications that might lessen the symptoms pending medical treatment?

Yes Sir there is severe risk of strong anaphylactic reaction at any age.
I trust you understand that I can’t reply in public to your 2nd question. I will PM you.

Vinegar and creams don’t help when your underwater and get stung. At that point you grab handfuls of mud or sand and rub the heck out of it. Same when in the surf. Like getting stung by a bee - you have to remove the stinger ASAP.

any kind of pressure on the area will cause the nematocysts to fire and make things worse. Vinegar reacts with the venom to reduce its effectiveness. Soaking in hot water will also do that. Luckily the moon jellies mentioned in the OP have very short tentacles, to they are relatively easy to avoid. Portugese Man-o-war have tentacles that can be 50 feet long or more, and have a much more potent venom. I swim around moon jellies....I exit the water for the man-o-war!

I had the absolute pleasure of having a blue-bottle tentacle go down the collar of my wetsuit as I duck-dived under a wave when I was around 13yo. Not a recommended experience.
