There are loads of unknown (to science) deep sea sharks out there, most of them quite small. A friend of mine in grad school spent several trips on a deep sea trawler out of Madagascar and described multiple new species.

Sometimes the first opportunity to see something occurs while you are actively destroying the habitat where it lives. Sounds like your friend's work took advantage of the access that deep sea trawlers would have to species unknown to science, allowing them to have a rough idea of their distribution. In a sense this is very useful to researchers who can argue the case that trawling is too destructive for that area due…

No one is mining manganese from the sea floor. The whole idea was a CIA cover story for a mission to recover a sunken Soviet submarine that the Americans knew the location of but the Soviets didn't. They needed an explanation for a cargo ship headed out to a specific area with deep sea construction equipment on board: https://en.wikipedia.org/wiki/Project_Azorian

me before opening: is this just going to be goblin sharks the article: Goblin sharks have never before been filmed in their natural habitat Surprisingly bad headline.

LLMs are obsessed with hidden, never seen before goblins - I suspect this is why this story has been doing so well.

Could the light be blinding all the animals? I would assume their eyes would have evolved to be extremely sensitive to light.

Probably, most sharks have nictitating membranes to protect the eye, but this family of sharks didn't evolved one apparently. In any case, they can avoid easily the light source swimming away.

yeah, calling these sharks who are native to our world 'alien' is kinda off-putting and obviously click-baity.

It was a cover, but they did not invent it. It is an actual sudied thing and there has been some experimental mining operations as well.

They're mining them now. They weren't then.

Yes, there is an issue with exploration lights effecting native life.

Recent attempts to capture a giant squid on video were only realized when they switched the lights off.
