What is this?


Commentary by Prof. Yuji Tsukii, Hosei University
I don’t know what this is. It is probably not a living organism.

In nature, there are crystals called plant opals which originate from plant cells.

Plant opals exhibit various shapes depending on the plant species. However, the image in this video does not exhibit a normal shape, so it may not be a plant opal.

Sampling Date : 27 May 2009
