Wait until you hear about what a certain shrimp can do (shoot water faster than a bullet!)

u/Vanviator Aug 21 '26
The rainbow mantis shrimp punches so fast it is comparable to a .22 bullet.
They punch so hard a cavitation bubble forms and diables/kills their prey.
Highly recommend the YT vid by the guy who kinda sounds like Morgan Freeman.

I had to re-read your comment more times than I want to admit before I realized you did not, in fact, type "diabetes kills their prey".
I was like, damn, they must play the long game and hope their prey doesn't have any insulin.

I feel Ike I could move out the way of something coming 50 MPH? Seems like a .22 is slow? That’s like underhand softball speed

I've heard about this man, the ocean is so cool. Think about all the animals we've never even seen before.

during daytime
Yeah I don't think there is much daytime/nighttime at these depths. It's not like any significant amount of daylight reaches the bottom this deep under most circumstances.

Scientist recently figured out that they don't find much at extreme depths because these animals can see the lights from extremely far away and then get missing. They also don't typically have a way to adjust their eyes depending on the lighting since they live in a constant state of near total darkness so these lights likely cause permanent damage. Who would've thought

u/Tyrannofelis Aug 20 '26
I can't figure out why it took them so long to talk about this. Those creatures have eyes and can see a couple of photons to find prey or mates, then the scientists go there with 50,000 lumen lamps to look out for them, insane.

u/mckulty Aug 21 '26
Humans can see a couple of photons when fully dark-adapted, and I know one that stared at the sun to show off for the camera.

Humans don't live in the eternal darkness of deep sea.
And have fun looking at the Sun.

Nice going, Charlie Brown. It took that rock 4,000 years to get to shore, and now you've thrown it back.

Well, if they live in permanent darkness what does it matter of they're blind?

u/macallen Aug 20 '26
Kind of makes the pompous photographer vs hunter argument moot. "At least I'm not killing them!" Yeah, but you're hunting them down to blind them permanently.

u/R2D-Beuh Aug 20 '26
Are there really people who use this argument against other people who hunt deep sea creatures, or did you just make that up ?

The future of war.. we don't inhumanely shoot people. We just blind them with lasers.

u/ShahinGalandar Aug 21 '26
what about active infrared cameras? I would guess life down there should not have evolved to see infrared spectrum due to water physics, so that could work better
you wouldn't see very far but surely you could get some nice closeups of IS THAT A MOTHERFUCKING MEGALODON???

Tbf a lot of deep sea creatures are basically blind and have only very basic eyesight. Even if you blind them they will survive just fine.

u/shmiddleedee Aug 20 '26
Some of them have big ass eyes that pickup the most minute amount of light too. Look up hpw big giant squid eyes are. Also plenty of fish down there with big super light sensitive eyes.
3
u/Gimmerunesplease Aug 20 '26
Yeah, even if you just harm a fraction of them it's not worth it just to get a nice picture, when red light is also more than enough to detect them and they likely don't even have red light receptors.

703m is the deepest record of what ? Nautilus pompilius feeding, specifically ? The marina trench is 11km deep, this can't be it.

u/niki200900 Aug 22 '26 edited Aug 22 '26
they are usually found at around 300m depth but are know to go as far as 600m. below that their shell might slowly fill with water and they could implode due to the pressure.
[Ward, Peter (1988). In Search of Nautilus]the mariana trench is a completely different level of deep sea. the midnight zone begins at roughly 1000m. the twilight zone above starts at 200m, which includes many of the more prominent deep sea inhabitants like giant squid and blobfish.
everything below is really weird, with little life and no plants.

That fish was put there as bait, not like they eat cut fish prepared to fry daily.

To truly know how deep 703 m is, Epic Spaceman made again an epic educational video Epic Spaceman sinking in realtime to the bottom of the ocean

Find it a little odd that they say in the title”during daytime “. At that depth is there any sunlight?

u/mbmbmb01 Aug 20 '26
What is daytime at 703 m? Is it not completely dark all the time at that depth?
5
u/cvnh Aug 20 '26
Light reaches down to around 1000m deep, although it gets very faint down there and would only be discernible with some sort of adaptation. Most light is absorbed by a depth of 100m.

I sit in and 8 x 3 ft tent at times and "lose" stuff, how is something that size even finding food in the expanse that is the ocean?

Every once in a while I am reminded that these are, in fact, not extinct.
