I also found this mysterious, colourless jelly with rounded edges by the sea: [https://lh3.googleusercontent.com/-aBV7yZv6EJk/TQ6pUrMygSI/AAAAAAAAuas/vP7lxEsFm6k/s1600/DSC\_4012.JPG](https://lh3.googleusercontent.com/-aBV7yZv6EJk/TQ6pUrMygSI/AAAAAAAAuas/vP7lxEsFm6k/s1600/DSC_4012.JPG) And I’m wondering what it is.

To the OP: [Probably this guy.](http://www.usm.edu/news/article/purple-striped-jellies-abundant-near-barrier-islands)

To AaronX, that looks like a part of a jelly fish.

AaronX, yours could be [the egg sac](http://www.ncmg.org.au/Story32.html) of a sand snail.

Ah, that looks exactly like what I saw! I thought the dots inside were bubbles. But isn’t that egg sac as big as the snail itself?

Stomolophus meleagris

That article says “purple striped jelly” which I know is mostly a west coast thing, _Chrysaora colorata_. Wikipedia says that one (more accurate) is sometimes called a “mauve stinger,” but no US name is given.

Maybe, but someone else told me it was Irving.

Perhaps - but bear in mind, it’s mostly water - the snail only needs to secrete the protein/saccharide matrix of the jelly, and the environment provides the hydration to pump it up to that size.

Yeah, I figured that’s the only way they could manage it. I wonder how they prevent it from dispersing? Is there a “skin”?

[http://www.southernshores.auz.info/beachcombing/archives/nov.htm](http://www.southernshores.auz.info/beachcombing/archives/nov.htm) has pictures that look the same, and the description matches mine - November, in Victoria, Australia.
