Not a fact but a question:
How do whales keep water out of their anuses when they are deep diving?
Whales have been known to dive almost 2 miles deep and at that depth youāre looking at almost 300 atmospheres of pressure and a whaleās sphincter has to be strong enough to resist that.

I had to look it up out of curiosity. The rib cage and lungs of sperm whales are adapted to collapse under pressure, squeezing all the air in the lungs into a small space and increasing internal cavity pressure.
They can if they do too many dives in rapid succession.
You get the bends by having a lot of nitrogen dissolved on your bloodstream due to the pressure. So itās a function of how much nitrogen you breathe, how much pressure youāre breathing it at, and the total amount of blood (and some other tissues) in your body that can absorb that nitrogen. Divers get the bends because they are taking multiple breaths of air under pressure, there is multiple lung volumes of nitrogen cycling though the diver. Whales and other diving animals donāt typically āholdā their breath when they dive, but if they did, it would only be 1 breath of air for the entire dive. Air in the lungs is bouyancy they donāt want and can potentially injure them when it re-expands. Most marine diving animals will saturate their blood and muscles with oxygen at the surface and then dive and exhale.

Lobsters have olfactory sensory neurons, located in the aesthetasc sensilla on their antennules, which allow them to detect the pheromones in the urine of other lobsters.
A dominant male lobster will pee to signal his dominance and deter other males from his territory. Females may also pee to signal their readiness for mating, and the urine of a dominant male can attract females.
Lobsters also communicate through touch and by using their claws, but no one really gives a fuck after reading about the pee thing.

Lobster: I canāt understand what you said, please piss it slower for me.
While this is funny and all, this isnāt really true for a couple of reasons:
We know a hell of a lot about the oceans, weāve studied them for hundreds years. There has been extensive mapping of the seafloor. All of the areas close to land have been thoroughly studied. And where weāve spotted interesting stuff, weāve investigated for sure.
We havenāt thoroughly explored the moon. Sure weāve had nice pictures for a long time. But weāve only recently seen the rear side of the moon, as we more or less always see the same side from Earth. Not till recent orbiters weāve had a high resolution map of the moon, comparable to maps we have of the oceans.
Only a dozen or so people have ever been to the moon and the amount of research they did was very low. They also havenāt brought back many samples. And the amount we can do from orbit and with rovers is very limited. At this point I would say we know more about Mars than we do about the moon, depending on how to count. The moon isnāt that interesting, so we havenāt done much with it. Itās made of the same stuff as the Earth and without an atmosphere and biosphere, itās kinda dull.
This is basically impossible to measure. What is knowledge? How is it quantified? We could say itās relative. But since there isnāt a way to know how much total knowledge there is available to learn, Iād say thatās not possible. What does it mean to āexploreā? Do people need to go there? Because a hell of a lot of people have been to the seafloor than to the moon. Hell going to the seafloor is a basic tourist activity these days. Iāve been to the Maldives and did some crazy dives looking at life on the bottom of the sea.
People might argue the Moon is basically all the same, so once youāve seen one spot youāve seen them all. Iād argue thatās not true, weāve only recently learned the moonās poles are very interesting and we know very little about that. And Iād counter that argument with the fact the same goes for the deep oceans. A whole lot of it is just barren wasteland, an under water desert. We havenāt explored because there is nothing to see. We select interesting locations and study them thoroughly, instead of studying a lot of it a little bit and wasting huge amounts of time.
Another argument often repeated is new species are discovered every day in the ocean. Whilst this is true, we are also destroying a lot of species, so the total number might actually go down instead of up. And a lot of species are variants of already known species. Only expert biologists can differentiate between the species and know what to look for. And Iād argue they donāt change the big picture or understanding at all. Still interesting, but not an indication there is so much more to find out there.
But what about something huge living down there? Like a Kraken or dinosaurs? Well no, we donāt have to have studied every square inch to know about big life. Big life is messy, requires a lot of resources and is part of a food chain. You donāt need to see the dinosaur if you can see their giant mountain of crap amidst broken trees. There might be some kind of large squid or something down there, but they will probably be extremely similar to other large squid we already know about. So a new species, but not changing the overall picture. If there were any big monsters down there, we would know about them by now.
So this is one of those things that might feel true, but in reality it really isnāt.

Greenland sharks are pretty amazing
They can grow up to 24 feet putting them at the same giant scale as great whites and basking sharks, but most are usually closer to 5 meters long
They can live for hundreds of years due to extremely slow metabolism and ambush feeding, some individuals found around 400 years old are as old as the Jamestown colony, Don Quixote, and the discovery of logarithms.
They are opportunistic feeders and have been found with polar bear and reindeer in their digestive systems, and can pull/vacuum in water to catch their primary prey of fish, eels, and other sharks.

Global warming has a slower effect on the oceans than in air temperatures, yet weāve passed a tipping point where many sea regions are consistently 3C warmer than pre-industrial era, and they are helping air temperatures set records too. Even since 2016, summer tropical North Atlantic ocean has been over 2C warmer than 2016. This region is also called āhurricane alleyā, and ocean heat has an exponential effect on hurricane strength.
My theory on tipping points with ocean to air temperatures is that El ninos cause a step up in air temperatures now. This happened in 2015/2016, where air temperatures stayed above 2015 levels every year afterwards, even if 2016 record stayed up for a long period. 2023/2024 was another step up. Ocean and air temperatures help each other set summer records, and that ocean heat persists into fall/winter to help moderate winter air temperatures, that makes spring have a head start on new summer records, or at least keep the new el-nino set baseline, until another step up the next el-nino.

There are lakes in the ocean called brine lakes/pools. Brine is essentially concentrated saltwater; its high salinity means itās denser than water.

It was never stated but I always assumed the āgooā referred to industrial waste. But SpongeBob creator Steve Hillenburg was an actual marine biologist and would have been well aware of brine pools, so thatās probably right.
Technically, brine just means a high concentration of salt in a fluid. It doesnāt necessarily have to be sodium chloride like we know, it can be other salts, like calcium chloride. Though the most common case for industrial brine is just desalination plants, other industries can still create brine, like mining/oil drilling. It also depends on how itās released. Large amounts dumped at once is the reason for manmade brine pools.
Itās also accounted for almost 100% by mosquitos, specifically the diseases they carryā¦so not really the mosquitos at all. Quick searching shows snakes following mosquitos with 100,000 deaths caused per year. In any case, the scale is prodigiously unbalanced. Human animals kill trillions of non-human animals, almost entirely for their own pleasure. Non-human animals kill a few hundred thousand human animals (or a bit over a million if you count mosquito-borne disease) in self defense or by accident.
Not sure what your definition of people is, but Mexicans, Ugandan, and Koreans all eat grasshoppers (and probably others). I know crickets are eaten in Southeast Asia.
Ants seem too tiny to try to eat, but a Google search reveals they are eaten in South America and Southeast Asia.
An āinsectā or ābugā is an arthropod with six legs in the class Insecta. Thereās also ātrue bugsā which are in the order Hemiptera (or even just the suborder Heteroptera if you are super nitpicky) - this includes things like leafhoppers, aphids, assassin bugsā¦
Within Insecta, we have Hemiptera, Hymenoptera (ants, bees, wasps), Coleoptera (beetles), Lepidoptera (butterflies, moths) and Odanata (dragonflies, damselflies).
To get to crabs, lobsters, and shrimp, you have to zoom out to jointed exoskeletons - Arthropods. (And I think crabs are a clusterfuck that make cladists cry, Iām in a landlocked state and havenāt got to do much ocean science myself so wonāt put my foot in my mouth there.)
Other things that are ānot bugsā but often called such - spiders, scorpions, whip scorpions and vinegaroons are all Arachnids (arthropods with specialized limbs called chalicerae - those cool things at the front of a spiders mouth), Rollie pollies/pill bugs are Isopods. Centipedes and millipedes are Myriapods.
Your larger point about how itās weird that people get grossed out by the idea of eating mealworms but are okay with chowing down on shrimp is a good one though.

When a whale dies and its corpse falls to the bottom of the ocean, entire ecosystems rapidly develop around eating every part of it due to how scarce resources are in the deep ocean. This phenomenon is called a āwhale fallā and itās a major source of energy for deep ocean ecosystems.

There are many tube worms that do have digestive tracts, but I assume you are talking about chemosymbiotic tube worms that are found in methane seeps and hydrothermal vents. These guys essentially live in farts (hydrogen sulfide, methane), which their symbionts use for chemosynthesis.
Depends, some pictures I see that get posted on places like that look perfectly fine to swim across to me. Like itās just the sea in a calm day and you canāt see the bottom. Actually the same happens at the beach where I live but that is because the water is so cloudy, slopes off steeply though, especially at high tide. So usually canāt stand up except right at the shore line.
Norwegian fjords are freaking deep. When youāre on the shore of Sognefjord, youāre standing in front of a 1300m deep canyon filled with ocean water.
What I like to think about is that fjords were carved out by glaciers and the sea level has certainly been lower that it was now in the pastā¦ but 1300m deep what???
ā¦so how did Glaciers cut rock BELOW sea level? Like wayyyyyy below sea level?
It is the weight of the entire glacier bearing down and carving wayyyyyy below a depth that a chunk of ice would make sense being at, the entire glacier basically serves as a trench digging machine and as you pointed out these fjords are REALLY deep.
Well, changing it dramatically. Itās going to stay within historical ranges where ocean life flourished, but without any exoskeleton-heavy animals like corals in the mix.
Ocean acidification occurs because the ocean serves as a carbon sink. Excess carbon dioxide in the atmosphere forms weak carbonic acid in ocean water. The ocean has historically been slightly basic, and as it inches towards a neutral pH, it makes it impossible for things like oysters to form their shells.
One big problem is that itās one of the biggest carbon sinks. Itās keeping that greenhouse gas out of the atmosphere. However - as you might notice if you leave a can of Coke out on a hot day - the solubility of gases in liquids decreases when itās hotter. The world heats up because of greenhouse gasses, less greenhouse gasses can be stored in the ocean and re-enter the atmosphere, which heats the world up moreā¦
Then we also have the lovely āice albedoā positive feedback loop - dark ocean water absorbs more of the suns radiation, sea ice reflects more of it. Sea ice melts as earth heats up, exposing dark ocean which absorbs more heat and melts more iceā¦.
Pretty much. We set off several positive feedback loops and punctured the equilibrium, and natureās going to have to find a new one. Whether or not that can support life as we know it know is up in the air.
(I didnāt even mention phytoplankton die offs - a lot of the oxygen produced on earth is from photosynthesis happening in the ocean - not from terrestrial plants. So you also have less of a carbon sink in that process as well.)
When I was a child, long road trips would leave the front grill of our car caked with bugs. When Iād hunt for dandelions with my siblings, leaning close to the ground revealed a world just teeming with activity.
Now - where are the bugs? Especially with how difficult it is to identify insect species, weāve probably lost hundreds of thousands of bugs that were never named or studied. How critical were those bugs to their ecosystems?
Itās difficult to motivate people to care about species of phytoplankton or ants though. Even the āsave the beesā thing got twisted into a celebration of non-indigenous species that were brought in for agricultural purposes (wasps are critical for pollination, but not as cute as honey bees I guess.) The more you study ecology, the more you realize how complicated and interlocking it is, the more you realize that most human beings cannot be brought to care without substantial changes to our education system.
Well at least thereās not a fuckton of methane hydrates on the ocean floor that are now releasing a greenhouse gas 30 times more potent than CO2 refrom the ocean floor as the water gets warmer. And that isnāt a self-feeding loop that means itās probably too late to save ourselves now.
Methane at least breaks down faster than CO2. Heavier, so stronger effects, but at least the CH4 breaks down after a decade or so instead of centuries.

Whales suffocate to death; they donāt drown.
Human breathing is controlled by the autonomic nervous system. We have to hold our breath on purpose to stop ourselves from automatically breathing. This makes us passive breathers.
Whales, however, are active breathers. They must choose to inhale which is why they can sleep without sucking in air. When they get too old, sick, or weak to surface, they suffocate.
Bonus fact: whales canāt breathe through their mouths; it goes straight to the stomach. The blowhole is the only respiratory tract.

weird how people will eat lobsters and crabs, but wonāt eat grasshoppers and ants.
Not sure what your definition of people is, but Mexicans, Ugandan, and Koreans all eat grasshoppers (and probably others). I know crickets are eaten in Southeast Asia.
Ants seem too tiny to try to eat, but a Google search reveals they are eaten in South America and Southeast Asia.
Arthropods, not bugs.
Does ābugsā have a scientific meaning? I was assuming it was a laymanās term that I could abuse.
An āinsectā or ābugā is an arthropod with six legs in the class Insecta. Thereās also ātrue bugsā which are in the order Hemiptera (or even just the suborder Heteroptera if you are super nitpicky) - this includes things like leafhoppers, aphids, assassin bugsā¦
Within Insecta, we have Hemiptera, Hymenoptera (ants, bees, wasps), Coleoptera (beetles), Lepidoptera (butterflies, moths) and Odanata (dragonflies, damselflies).
To get to crabs, lobsters, and shrimp, you have to zoom out to jointed exoskeletons - Arthropods. (And I think crabs are a clusterfuck that make cladists cry, Iām in a landlocked state and havenāt got to do much ocean science myself so wonāt put my foot in my mouth there.)
Other things that are ānot bugsā but often called such - spiders, scorpions, whip scorpions and vinegaroons are all Arachnids (arthropods with specialized limbs called chalicerae - those cool things at the front of a spiders mouth), Rollie pollies/pill bugs are Isopods. Centipedes and millipedes are Myriapods.
Your larger point about how itās weird that people get grossed out by the idea of eating mealworms but are okay with chowing down on shrimp is a good one though.
When a whale dies and its corpse falls to the bottom of the ocean, entire ecosystems rapidly develop around eating every part of it due to how scarce resources are in the deep ocean. This phenomenon is called a āwhale fallā and itās a major source of energy for deep ocean ecosystems.
Sometimes I wonder if a shipping container full of billionaires would have a similar effect.
We have to find out. We need to try it immediately to see what happens. Thatās just basic science
That seems like a waste of a perfectly good shipping container.
Why donāt we just use environmentally friendly hemp ropes and locally sourced boulders?
Locally sourcing boulders over the Marianas Trench is going to be such a pain. Iām pretty sure the environmental benefits will outweigh importing some nice basalt from Hawaii before we leave out.
Or a submarine.
Whale whale whale, what do we have here? - deep ocean crabs

Fun Fact: Dolphins fart.
I mean everything farts, right? What about a snail?
Itās a delicacy in France. Escargot de poopoo
Due to their plant-based diet, I can imagine that snails fart a lot.

tube worms donāt have digestive systems of their own. it is possible they donāt fart. The bacteria they symbiose with might fart on their behalf though.
There are many tube worms that do have digestive tracts, but I assume you are talking about chemosymbiotic tube worms that are found in methane seeps and hydrothermal vents. These guys essentially live in farts (hydrogen sulfide, methane), which their symbionts use for chemosynthesis.
And so do fish.
Thalassaphobia is a real thing
I, for one, think itās completely fucking reasonable to afraid of deep, dark water. Phobia my ass.
Some phobias are irrational but thatās not part of the meaning of the word
Depends, some pictures I see that get posted on places like that look perfectly fine to swim across to me. Like itās just the sea in a calm day and you canāt see the bottom. Actually the same happens at the beach where I live but that is because the water is so cloudy, slopes off steeply though, especially at high tide. So usually canāt stand up except right at the shore line.
ā¦ And thereās a community for it

Norwegian fjords are freaking deep. When youāre on the shore of Sognefjord, youāre standing in front of a 1300m deep canyon filled with ocean water.
New anxiety unlocked.
What I like to think about is that fjords were carved out by glaciers and the sea level has certainly been lower that it was now in the pastā¦ but 1300m deep what???
ā¦so how did Glaciers cut rock BELOW sea level? Like wayyyyyy below sea level?
It is the weight of the entire glacier bearing down and carving wayyyyyy below a depth that a chunk of ice would make sense being at, the entire glacier basically serves as a trench digging machine and as you pointed out these fjords are REALLY deep.
They were carved by Slartibartfast, not glaciers.
where is your proof? If Slartibartfast did it you would be able to find his signature somewhere in the work.
The mouseās design specifically excluded any artistsā signatures.
Typical mice nonsense, did they even thank us for all the cheese?
No but the dolphins said āthanks for all the fishā before they leave.
We are killing the ocean by increasingly acidifying it. This has been known by scientists for decades.
But have you thought of the benefit? Free club soda!
All crabs are now soft shell crabs! Think of the deliciousness!
Well, changing it dramatically. Itās going to stay within historical ranges where ocean life flourished, but without any exoskeleton-heavy animals like corals in the mix.
Ocean acidification occurs because the ocean serves as a carbon sink. Excess carbon dioxide in the atmosphere forms weak carbonic acid in ocean water. The ocean has historically been slightly basic, and as it inches towards a neutral pH, it makes it impossible for things like oysters to form their shells.
One big problem is that itās one of the biggest carbon sinks. Itās keeping that greenhouse gas out of the atmosphere. However - as you might notice if you leave a can of Coke out on a hot day - the solubility of gases in liquids decreases when itās hotter. The world heats up because of greenhouse gasses, less greenhouse gasses can be stored in the ocean and re-enter the atmosphere, which heats the world up moreā¦
Then we also have the lovely āice albedoā positive feedback loop - dark ocean water absorbs more of the suns radiation, sea ice reflects more of it. Sea ice melts as earth heats up, exposing dark ocean which absorbs more heat and melts more iceā¦.
Tl;Dr
We fucked yo
Pretty much. We set off several positive feedback loops and punctured the equilibrium, and natureās going to have to find a new one. Whether or not that can support life as we know it know is up in the air.
(I didnāt even mention phytoplankton die offs - a lot of the oxygen produced on earth is from photosynthesis happening in the ocean - not from terrestrial plants. So you also have less of a carbon sink in that process as well.)
When I was a child, long road trips would leave the front grill of our car caked with bugs. When Iād hunt for dandelions with my siblings, leaning close to the ground revealed a world just teeming with activity.
Now - where are the bugs? Especially with how difficult it is to identify insect species, weāve probably lost hundreds of thousands of bugs that were never named or studied. How critical were those bugs to their ecosystems?
Itās difficult to motivate people to care about species of phytoplankton or ants though. Even the āsave the beesā thing got twisted into a celebration of non-indigenous species that were brought in for agricultural purposes (wasps are critical for pollination, but not as cute as honey bees I guess.) The more you study ecology, the more you realize how complicated and interlocking it is, the more you realize that most human beings cannot be brought to care without substantial changes to our education system.
Well at least thereās not a fuckton of methane hydrates on the ocean floor that are now releasing a greenhouse gas 30 times more potent than CO2 refrom the ocean floor as the water gets warmer. And that isnāt a self-feeding loop that means itās probably too late to save ourselves now.
Because that would be bad.
Methane at least breaks down faster than CO2. Heavier, so stronger effects, but at least the CH4 breaks down after a decade or so instead of centuries.

Sharks are older than trees and the north star.
And some living sharks are more than 200 years old, probably.
There could be a Greenland shark alive today that was alive when Columbus was crossing the ocean.
The perfect killing machine
And Saturnās rings!
A teaspoon of seawater typically contains about fifty million viruses

Well yeah our water companies keep dumping raw sewage into them
Earthās atmosphere is an ocean of gas. The ocean is an atmosphere of liquid. Words are made up.
Yea, for a reason.

Did you know fish fuck in the ocean? Remember that, when you go for a swim.
Assert dominance: Fuck the fish.

Whales suffocate to death; they donāt drown.
Human breathing is controlled by the autonomic nervous system. We have to hold our breath on purpose to stop ourselves from automatically breathing. This makes us passive breathers. Whales, however, are active breathers. They must choose to inhale which is why they can sleep without sucking in air. When they get too old, sick, or weak to surface, they suffocate.
Bonus fact: whales canāt breathe through their mouths; it goes straight to the stomach. The blowhole is the only respiratory tract.
Bonus bonus: a blue whaleās throat is so small it could choke to death on a grapefruit.
4" / 10cm throat
Iām sure their throat can be blocked that way; but if they canāt breathe through their mouth anyway, is it actually choking? Or just terminally blocked?
Fair point. I didnāt even consider the ramifications of wording it like that instead of just saying it has a small throat. I tend to use analogies a lot
Nah, it makes sense, and ice heard this phrasing before - just always wondered if they meant the poor whale couldnāt breathe, or basically just had indigestion!
The ocean has killed more billionaires than the Moon has.
Scoreboard, scoreboard.
ā¦so far
The Blue Whale is so large, that if you laid one out on a standard NBA basketball court, the game would be postponed.
