Of course I will! I still don’t know what it was! But it didn’t kill me!

I think it’s likely to be a sea gooseberry, a type of comb jelly or ctenophore (perhaps Pleurobrachia). It doesn’t have the stinging cells that all cnidarian jellyfish (scyphozoans, hydrozoans and cubozoans) possess.Underwater, the cilia on the ribs may create a rainbow effect or iridescence through light refraction.

Mertensia ovum - a ctenophore, also known as comb jelly.
From Claire Nouvian’s book, The Deep. Highly recommended. It’s a book that packs more than stunning photographs: the book details so much newly-gained knowledge of various deep-sea organisms, often photographed in situ. 
Note that the iridescence often observed on a ctenophore’s ciliary rows are not an example of bioluminescence. It’s simply a refraction of light.
