Blue Moon (Actually blue moon Jellyfish)

This is very strange,I'm not used to uploading to the PC first from the phone, but now the end of the 365 consecutive days is in sight, I can't stop now!
(Just three more entries to go!)

The Jellyfish (and it's companions) are in a cylindrical aquarium in "The Deep" Hull's Aquarium (A place I visit often in the cold weather)
