Maybe, maybe not.
If it's what I saw the other day up in the CLW area, I would be weary.
I saw a large stinging variety.

I have been riding and looking around a lot lately (I personally love seeing stuff while I ride).
I have seen some really cool stuff lately.
I saw a King mackerel skyrocket about 50 yards off the beach. He was at least a 20 pounder. I then saw the same or similar sized mackey "body surfing" a large wave. I have to assume he was doing it to conserve energy while sneaking up on bait. That was the first time I have ever seen that, btw, with a kingfish.

I saw a turtle in CLW pass two days ago. A bunch of dolphins.. etc.

Anyway, I spotted this rather large brown thing and went closer to inspect (basically ran it over, almost). Well, it was the BIGGEST friggin' jellyfish I have seen in a long time. The body was clear, but it's stingers were brown. It had a ton of stingers. Not one of those moderately harmless moon jellies either (moon's sting, but not bad, imo). This baby had tons of brown tentacles with stingers. It was going to mame whoever came into contact with it, basically.
I am pretty sure it was a sea nettle.

If you are seeing the same, I would stay away from them. They hurt real bad.
The one I saw was very large. It was obviously heavily laden with stingers.
I don't know about the ones you saw. But better safe than sorry.
I guess if they are all over the place it's hard to always avoid them.
Maybe purposefully put a finger (not whole hand) on one and see what happens (?).

I know a large stinging one, if it contacts a large area, can be a real bad deal and send many to the hospital.
Some jellies are harmless though.
