Again me & my never-seen-in-reality jellyfish (pictures and schemes in the biology book distort the whole perception :)! From Google I learned that the sea is not blue inside and corrected my mistake.
As far as I remember from my school years, jellyfish are multiplying by means of “gemmation”. :/ I thought it would be nicer if they were “budding” from the sea flowers.
Yep, dreaming is nothing wrong! :)))
