Concerning message #15503.

Dear Bill and Binyamin,
What an interesting problem regarding colour at depth. From my own experience I know that a diver, familiar with particular object, usually thinks that he can see different colours, regardless actual depth. Especially with very good visibility and lot of light.

Maybe the quickest way to check what happened here is to get another photo of the same species only in available light. If there is really a bioproduction of light, the red mantle border will pop-up from dull grayish rest of the picture.
Best regards,
aj
