What kind of Jellyfish is this

I see these every time I snorkel in the Caribbean. This one happened to be off the coast of grand cayman. The are usually about 2-4" when I happen to see them and are either a translucent white or a translucent tan color. Any ideas on an ID?

Can't really tell with that photo. I can't see tentacles or anything other than a pile of jelly. My first asumption was a box jellyfish, but again I can't see enough of it to say for certain.
 
I've never seen or noticed any tentacles in person on these either. Only distinguishable markings I've noticed are the longer bands going from its crown down its entire bell you can see in the pic. I haven't come across a pic of one like this yet. They can't be rare as I've seen them a few times and and plenty of them too. All while snorkeling in common places.

There are no box jellies in the Carribean. Could be a sea wasp, a close relative of the box jelly.

Sea wasp (Chironex fleckeri) is a box jellyfish,

... but after researching, it doesn't seem like that lives in the caribbean either. Malo kingi does though, but it's way too small..

Looks like a comb jelly to me. These used to be grouped with regular jellies but now are in their own group. They are common in the Caribbean.
 
Most can bioluminesce and make light but there are lots of shallow water comb jellies. We catch/see them quite frequently in shallow caribbean and florida waters.
 
Only time you see comb jellies "glow" is at night when they are disturbed. When there are lots of a comb jellies in the water when night diving, it is quite cool to turn off you lights and wave your hands about...makes the jellies light up ;)

This is the ctenophore Mnemiopsis Leidyi .Is a deep sea and comes to shallow water also.Its bioluminiscent when disturbed and also reflects light with its combs.Its iridescent too.These things i think should be illegal to own or sale.For international trade they are banned for sure because these can be really nasty pests.

Youre 1 year late.

And that is a comb jelly. I heard you can buy them and get a special tank
 
They are illegal to sale internationally thats why you dont see manny ctenophores aquariums in peoples homes.If somme might try to sell them internationally might get with a jail sentence or criminal record.As for keeping them in the aquarium this is a job for the zoo or the city aquarium.

Except the hitchhikers you get :)

Not really, the only restrictions for them is dependent on the location where collection of anything in general is restricted. I've seen/known people who had comb setups before, besides public aquariums. I even know a supplier.

Same deal as sea dragons, they're illegal to collect where they are found but nobody will stop the guy selling babies from specimens they bred personally before they were illegalized.

Selling and collecting have two very different restrictions.

As for the concept of them being too dangerous to sell, tell that to the blue ring octopus owners.
