This is similar in size to the one I found

I was quite fascinated by them Gracie really, they couldn't hurt me and I didn't touch them, I was just wanting to take as many pictures as I could while it was there

Yes Jenny I guess you would think so but the names are logical, Watermen don'''t sting, the others do.
Gopler is the Scientific name for all Jelly fish which of course are not Fish at all.
I won't say what the Japanese names are. LOL

Thanks Tim - quite a surprise at its size

Wow, the man in the photo really gives a good perspective of the size of this jellyfish. You get some big ones down under!
