I kinda feel bad for deep sea fish who get filmed by submersibles for nature documentaries. imagine you're just chilling doing whatever the fuck you do down there, and suddenly a fucking robot whale monstrosity is shining the brightest light anyone in your entire evolutionary line has ever seen directly into your eyes. that shit is more Lovecraftian than anything that lives down there

Real talk. Homie was just minding his own 15000 psi business.

They don't have to see it for long, because any vision they may have had, will be lost forever after being blinded by these bright lights.

Yeah, I was under the impression that most deep sea creatures we capture on film are dead a few hours later, either because they were blinded and now easy prey, or that in some cases it's like a massive instant sunburn since they have no natural UV protection.

Our flashlights aren't pumping UV, not like sunlight anyway. And just because it's hella bright to them, I wouldn't think our lights are energetic enough to damage tissue.

[–] fishos@lemmy.world 2 points 2 days ago

It literally damages the photosensitive cells they use to see. Like hella amounts, bruh.

Feels like that isn't a problem because most would have vestigial eyes at this point anyway.

No sunlight is making it a kilometer down.

A bunch of stuff down there uses bioluminescence to communicate.

And all you need are some light sensitive cells, not much in the way of eyeballs.

[–] fishos@lemmy.world 7 points 2 days ago

Those "light sensitive cells" are literally the eyes.

Golden rule man, I’m totally down if a giant robot whale comes to visit me

Fucking sperm whales: lets evolve from land herbavores to dive down and hunt what would be by all rights deep sea apex predators

I mean to get something that big on land, it would literally have to be a dragon flying around with a huge range to eat bears or something all over California. It's nuts

To get land animals that big the environment just needs to be different than it is today, which is how we got giant dinosaurs
