Another interesting link: perhaps this creature is now dead because of the format of the discovery https://www.reddit.com/r/askscience/comments/2n1yd4/how_is_it_that_when_deep_sea_creatures_are_filmed/cm9t27t/ https://www.reddit.com/r/askscience/comments/2n1yd4/how_is_i... > I'm a marine biologist and one of my former professors actually did all his research on deep sea eyes, mainly in invertebrates. I asked him about it once, about whether or not it was harmful to have the submersibles blasting white light around everywhere, and his answer was "yep, most of those animals are now blind and will likely die." Research subs usually use red light when in the deep sea since 99.8% of animals can't see it (red is the first wavelength filtered out in seawater so there is no red light at depth. Almost all deep sea organisms don't even have photoreceptors to see it) and it's not harmful. The white lights are mostly used for filming purposes. But yeah, they absolutely are being blinded most of the time.
