Jelly

Diatoms do have silica cell walls but thier life processes are organic ie carbon based.

I don't think there are any known silica or inorganic based life forms. Remember that classic Star Trek episode?

Could it be digested diatoms?
All organic bits digested and the silica left. What creature would do that?

Mystery solved by the WFF yet again.

This has to be one of the best windows on natures fascinating world around.

I bet darwin would be proud of us. Well done Gav  :allhail

I think that's the most likely explanation that sounds creditable to me.

Had some of these jellys in the back yard. I have a wee tray that I sit some plant pots on like a water bed to keep them moist. A few slug pellets had fallen past the pots and a slug(deceased) was encased in the jelly eing digested I think. Interesting thing is that several jellys had formed away from the slug and some seemed to be active on the slug pellets.

There must have been about 10 of the things almost floating in the tray of rainwater and various matters.
