The claim that is the first time filmed seems very strange to me. Could be true. I don't know, but chimaera are relatively common and relatively well known species for its habitat. I had one (dead) in a jar for several years in fact. On the other hand, is true that are related with sharks, but is a totally different kind of animal.

Too bad there are more comments about the format of the discovery, than the actual discovery. I gathered that this is not actually the first time a ghost shark was caught on camera, but the first time it was filmed in its natural habitat. It was seen alive in California and Hawaii in 2011 [0]. There are other ghost shark photos, such as this one (date unknown, file uploaded July 2016) [1]. Video has even existed, suc…

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_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,…

So, that could be the reason for the way this animal behaves (in my amateur opinion a bit aimless), too?

If you feel better, this fishes can probably survive even being blind. Sharks have complex and sophisticated senses related with smell, touch and taste, and can also sense electric fields emited by preys (or machines)

Looks more curious than afraid. Investigating the camera probably. If feeling pain would swim away.

A healthy fish also; not parasites at sight.
