Well take a LOOK! What would YOU call them?
Discovered at a depth of over 8500 feet, these beautiful and mysterious life forms are unlike any known jellyfish. What no-one knows is, why are they pink? Colour is theoretical at that incredible depth, as there are no naturally-occurring light sources except the glow of the phosphorescent hunters. If there are gay rights activist/jellyfish enthusiasts out there, this is definitely their totem animal.
The new species is from the Cnidarian (phylum of jellyfish, corals, anemones) order stauromedusae… The new species is unusual in its color (pink) and its proximity to to the superheated vent fluids.

So of course it is pink – it has been burnt by all that superheated venting stuff!

Probably for the best. You don’t want to play the Britney Spears sex tape game in that frame of mind.
Nor at that depth, surely.
Britney Spears has depth?
Depends which angle of access you’re talking about. I’ve heard amazing things about her vent.
