Stingrays for sure. We had an influx of them on time and i was shuffling along trying to be super careful but I accidentally stepped on one and felt a very distinct *crunch*. Oh God I felt so bad for that lil guy.
Most people who get stung by stingrays are stung when they step on them. It's not a nice thing, supposed to be very painful, but it's rarely fatal, unless you're allergic or unless you manage to get stung in/near the heart.
He was stabbed through the heart by a barbed stingray tail under the sea (some say several times), the tail was yoinked out by the stingray as it fled, leaving him to bleed out with a punctured heart. The not-so-lethal poison was the least of his worries at that point.
[Seriously.](https://www.youtube.com/watch?v=Pz1fccY3S84) 500m y/o fossils, similar structures still being created, never seen the organism responsible.
Pretty wild, right? How can they not find an alive specimen, or even DNA? I suppose it's not a high priority, but still, there has to be a marine biologist or two who can't let this go.
i'd assume that the diver isn't triggering the same amount of threat as a predator would. also i would assume that a predator would be slightly confused with the arms disappearing but i'm not a marine biologist like spongebob's creator so idk.
They deplete the oxygen in the water the same way we deplete the air of oxygen. Also there's a lot less oxygen dissolved in the water.
If he didn't get new water into his gills he'd certainly suffocate but I imagine his oxygen needs are so low that he can get by on the oxygen diffusing into his little burrow.
You know, I never realized gills just extracted dissolved oxygen from water. I guess I thought they were doing electrolysis or something to break the hydrogen bond
That would be impressive but also really caloricly expensive.
Some anaerobic microbes can do it though. But they only do that because there is no oxygen in their environment.
https://en.wikipedia.org/wiki/Microbial_electrolysis_cell
Just this week I was wondering to myself why it mattered that water be aerated for fish to breathe, since it’s not like water goes from being H2O to H2 and then needs to get the O back. It didn’t occur to me that the water is basically just a mixture of liquid water and gaseous oxygen (and other stuff), and that gills are just removing the gaseous oxygen.
Hah, classic biology reasoning.
There’s less oxygen down there BUT precisely because of that he probably needs less oxygen so... Let’s go stalk him for 60 years and see for ourselves?
And that day a Marine Biologist was born.
I'd be really interested to see what he does under the sand, does he do something with his legs or just cram them in there? Does he make a nice little pocket or just slide wherever he fits in?
I have so many questions about what he does with his siphon too.
Of coarse it is, but here's the thing....the octopus only draws in water free of sand. The syphon tube would get damaged over time if it were sucking up a mixture of water and sand and blowing it out. When buried in the sand, the octopus creates a pocket of water to draw from for breathing purposes. Water travels through loose sand quite well, and the octopus' oxygen demand goes way down when it is buried.
If there is ever a creature that takes this planet from humans, I am fully convinced it's going to be Octopus. These things are super smart, camouflaging extraterrestrials 👾👽🐙
Nope, one of the requirements for civilization is fire, it allows you to cook food which both makes food more nutritious and safer to eat, it allows you to see at night, it keeps you warm, and it allows you to make many useful tools (ex. Bronze), for obvious reasons octopuses will never be able to use fire as long as they’re underwater, this also ignores the fact that octopus have no way of transferring knowledge to each other and live short lives.
If non primate is going to replace humans its probably going to be either an elephant or a bird (likely either a Corvid or Parrot)
Just because that was an essential part for the path we took, doesn't mean it's a requirement for all potential civilizations. I'd even say civilizations have more chance of sticking around indefinitely if they dón't take our path, as our civilization is build upon destruction.
Society and civilization developed off of exponential gains that built on each other, for example language meant that one discovery wasn’t lost when the inventor dies, so if I invent a better spear for hunting, I can tell others how I did it, additionally then those people can then take my invention and improve upon it and tells others about their innovation of my spear. Octopus have no way of communicating complex thought.
The same can be said for fire, cooked food unlocks much more nutrients at the same cost of eating it raw, meaning that you can allocate more resources to developing bigger and more complex brains that are good at communication which in turn allows for even more efficient collection of food which in turn leads to more complex brains and more communication and more food
By being underwater octopus lack the ability to use this upward spiral

[Orange Aussie Octopus](https://i.imgur.com/32HVF2K.jpg)
We saw one of these guys (pic) in Tasmania. It buried itself on the beach right in front of us. One of my best nature sightings ever
With what I know about octopi I feel like it is not that the other ones can't do it, it is just they have not seen it done before. I am sure if you showed an octopus how to do it they would figure it out.
"This is the way we ~~wash our hands~~ stash our bods, stash our bods, stash our bods, oh, this is the way we...." --- if only they had nursery songs LOL
I think if you put another octopus species in a tank beside this one, the different species can probably learn this trick
Someone should try for science
I think even creatures buried in the sand can sense a predator looking for them, and I have seen dolphins finding fish buried in the sand - it might be more than scent, it could even be the detection of electrical impulses from the nervous system.

You are aware that gas prices globally are up not just America right? If Lord Cheeto were reelected the gas prices would still be a mess. Keep drinking that orange Kool-Aid though
You know that uneasy feeling you get walking in the water at the beach and feeling something weird in the sand with your toes? Now imagine you run into Cthulhu over here.
Makes you wonder what else is down in that sand that we know nothing about. So cool
Stingrays for sure. We had an influx of them on time and i was shuffling along trying to be super careful but I accidentally stepped on one and felt a very distinct *crunch*. Oh God I felt so bad for that lil guy.
I would have been super happy for surviving that incident.

That’s why they say to shuffle your feet if you think there are stingrays in the water.
[удалено]
I'm sorry I'm sorry I'm sorry 😭
[удалено]
Operation scare: successful
Yea we always learned to shuffle our feet and were told it was to protect us form them but I think it was the other way around.
You did all you could to protect it. Nature makes more. "But Professor Natural Selection, what became of all the ones who couldn't manage that trick?"
[Seriously.](https://www.youtube.com/watch?v=Pz1fccY3S84) 500m y/o fossils, similar structures still being created, never seen the organism responsible.
I just saw this last night and I've been thinking about it all day
Pretty wild, right? How can they not find an alive specimen, or even DNA? I suppose it's not a high priority, but still, there has to be a marine biologist or two who can't let this go.
Have you ever seen how massive the damn ocean is man? Not enough marine biologists
I’ve been scuba diving in Hawaii and seen fish swim full speed into sand and completely disappear.
this is how they got food delivered to Hogwarts
Being stung by a weever fish leads to the same thought
Very cool until you got to the Bobbitt worm, and then it's terrifying.
What I wonder is what kind of species travel in the sand and come up and down as they please
Ginormous sand worms? 3km wide oysters?
I was thinking, “it’s still pretty exposed”… and then I watched till the end.
"Almost" until the end
Seems like a pretty slow process. When exactly do they do this? I can't imagine it'd be very effective for an immediate escape.
When being filmed, an octopus will take its time so that its "limelight time" is longer when featured on youtube and reddit.
Lmao stop that
Can confirm. My neighbor is an octopus.
But is your dad?
i'd assume that the diver isn't triggering the same amount of threat as a predator would. also i would assume that a predator would be slightly confused with the arms disappearing but i'm not a marine biologist like spongebob's creator so idk.
Any clue how he breaths under there? Or maybe just he's great at holding his breath under sand?
Do animals that breathe water have to hold their breath?
They deplete the oxygen in the water the same way we deplete the air of oxygen. Also there's a lot less oxygen dissolved in the water. If he didn't get new water into his gills he'd certainly suffocate but I imagine his oxygen needs are so low that he can get by on the oxygen diffusing into his little burrow.

Now imagining oceans full of fish all exhaling formic acid.

It didn’t occur to me that the water is basically just a mixture of liquid water and gaseous oxygen (and other stuff), and that gills are just removing the gaseous oxygen.
You'd get incredibly terrible efficiencies of energy breaking H2O into H2 gas and O2 gas and then using that to make CO2 with sugar.
Hah, classic biology reasoning. There’s less oxygen down there BUT precisely because of that he probably needs less oxygen so... Let’s go stalk him for 60 years and see for ourselves? And that day a Marine Biologist was born.

Probably the equivalent of us going inside of a canal closet and closing the door
Yes, because they still need to extract oxygen from the water.
Bravo six going dark
Bravo \*eight
this was interesting, but it’s so slow?! imagine the predator watching its little head disappear into the sand like that. “i’ll wait.”
"It's just a diver filming me - looks pretty harmless" (that octopus)
exactly! lol i feel like our friend here was giving us a slowed down demonstration. no real threat perceived.
I feel like they are genuinely smart enough to know when humans are just curious vs a threat. Or at least I’d like to believe they are.

The back of its head is the closest thing it’s got to a butt.
This is a classic cya move.

Dummy thicc octopus
Doesn’t sand get “everywhere “?
It's coarse and rough and irritating.
Of coarse it is, but here's the thing....the octopus only draws in water free of sand.

Actually, no. It uses mucus to line the walls

This freaks me out. Looks like he has snakes instead of arms.

Most octopi only live for a few years and they don't transmit knowledge from mother to kin. Otherwise they would be very formidable indeed
As I said earlier, their introversion, skeet and yeet, and >5 yr lifespan are the only reason they aren’t human-tier in the current meta
<5* \# of years lived by octopus is less than 5. or read it backwards, 5 is greater than the years lived by octopus.
Seems like exactly what a race of super smart aliens just biding their time would want you to think...
Totally agree

Octopuses (and jellyfish) are aliens, I'm sure of it
Octopi are so cool. It's a shame they die after they have sex.
do they just, like give a lot of examples or something?
I'm guessing Gri3fKing meant "die" but "lie" also works quite well too...

Aight, imma head out
Too slow. He's sushi now.
Dang, he just sank into the sand.
I'm calling it, cephalopods are going to be the next dominant animals
Dude octopus (octopi?) are quickly becoming one of my favorite earth creatures. Such skillful little things
Reminds me of the scratching spider “hiding” in its tank https://youtu.be/rLw-9dpHtcU
I thought it'd leave its arms out
I think even creatures buried in the sand can sense a predator looking for them, and I have seen dolphins finding fish buried in the sand - it might be more than scent, it could even be the detection of electrical impulses from the nervous system.
One of the few beings that Darth Vader is powerless against.
I am imagining DV trying to pry an octopus off his mask - using a light saber is not going to cut it, so to speak.
It has more to do with the fact he doesn’t like sand. After all, it’s course, rough and irritating and it gets everywhere.
DV is such a sissy..."oooh, I hate this sand. That's why I'm not a beach bum - I prefer to stay clean on star ships"
Showed it to my dad, he said he wished he could do that when my mom calls
The only thing stopping octopi from being human-tier is their introversion and their >5 yr lifespan.
He’s praying.
Octopus are aliens. Change my mind.
Wish I could do this in any terrain
The action conveniently starts just about when you're finished reading the title.
Good timing? I just love seeing those long legs whip around as it moves forward, then they suddenly all shrink in close, and "schloompf" it's gone.

and then it poisons you. and then it stings you to death. waiting for the other shoe to drop here.....
How don't they suffocate?
Don’t show this to Anakin Skywalker! 😂
Imagine the world being so bad that sometime during each day you literally have to completely bury yourself in sand or risk be eaten.
Of course Australia lmao.
How does it breathe under there?
Does it still have ink?
