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 âwhale fallâ and itâs a major source of energy for deep ocean ecosystems.

Sometimes I wonder if a shipping container full of billionaires would have a similar effect.
lagoon8622@sh.itjust.works â¨3⊠â¨days⊠ago
We have to find out. We need to try it immediately to see what happens. Thatâs just basic science
Zron@lemmy.world â¨3⊠â¨days⊠ago
That seems like a waste of a perfectly good shipping container.
Why donât we just use environmentally friendly hemp ropes and locally sourced boulders?
trueheresy@lemmy.dbzer0.com â¨3⊠â¨days⊠ago
Or a submarine.
Baguette@lemm.ee â¨4⊠â¨days⊠ago
There are lakes in the ocean called brine lakes/pools. Brine is essentially concentrated saltwater; its high salinity means itâs denser than water. On rare occasions, brine doesnât mix enough with the existing saltwater around it, sinking to the bottom of the ocean and forming these lakes. The lake itself is usually devoid of life; brine itself is so salty that animals go into toxic shock if exposed for too long. However, the edges usually are full of life, where usually things like mussels and other extremophile organisms thrive.
Side note, subnauticaâs lost river is based off of this. No big leviathans in real life though, at least none observed yetâŚ

Similarly, SpongeBobs Goo Lagoon is a brine pool.
LovableSidekick@lemmy.world â¨4⊠â¨days⊠ago
It was never actually stated but I always assumed Goo Lagoon was industrial waste (âgooâ). But SpongeBob creator Steve Hillenburg was a marine biologist who would have known all about brine pools, so that speculation is probably right.
XiaCobolt@hexbear.net â¨4⊠â¨days⊠ago
Itâs the explanation for the beach Spongebob visits too
5too@lemmy.world â¨2⊠â¨days⊠ago
Wow, I had no idea these were a thing⌠and itâs so funky how the surface of the brine pool interacts with the surrounding seawater!
LanguageIsCool@lemmy.world â¨4⊠â¨days⊠ago
Amazing
HobbitFoot@thelemmy.club â¨4⊠â¨days⊠ago
There are entire levels of the ocean where ecosystem is fed on the slow sinking of dying animals.

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.
Devadander@lemmy.world â¨4⊠â¨days⊠ago
24 feet ~ 7.3m
5m ~ 16â5â
myrrh@ttrpg.network â¨4⊠â¨days⊠ago
âŚi was going to say 16 â feet based on 1 ½ meters being about 5 feet, pretty closeâŚ
MeatPilot@lemmy.world â¨4⊠â¨days⊠ago
They also commonly have eye parasites that severely impairs their vision or blinds them called Ommatokoita elongata.
So they get to live long with multiple generations of parasites stuck in their eyes they canât get out.

Be me young shark, ready to make my mark on the world Find a book falling from the sky called Don Quixote eh_mid.jpg Ignore humans for a few hundred years, eat some fish instead Find out itâs become a core component of their identity and everyone knows about it Even had a ballet about it wtf
lagoon8622@sh.itjust.works â¨3⊠â¨days⊠ago
Don Quixote is actually an awesome book, you should definitely read or listen to it. Give it a bit to get rolling, and you will absolutely be doubled over with laughter
notabot@lemm.ee â¨3⊠â¨days⊠ago
So 5 meter long sharks with 24 feet? That sounds terrifying. How far up the beach can they run?
MonkderVierte@lemmy.ml â¨4⊠â¨days⊠ago
feet ⌠meters
Oh, please.
MonkderVierte@lemmy.ml â¨4⊠â¨days⊠ago
Are they the ones where you have to ferment the flesh or it is toxic? Or wasnât that a shark?
Thorry84@feddit.nl â¨4⊠â¨days⊠ago
While this is funny and all, this isnât really true for a couple of reasons:
- We know a hell of a lot about the oceans, weâve 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 weâve spotted interesting stuff, weâve investigated for sure.
- We havenât thoroughly explored the moon. Sure weâve had nice pictures for a long time. But weâve 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 weâve 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 havenât 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 isnât that interesting, so we havenât done much with it. Itâs made of the same stuff as the Earth and without an atmosphere and biosphere, itâs kinda dull.
- This is basically impossible to measure. What is knowledge? How is it quantified? We could say itâs relative. But since there isnât a way to know how much total knowledge there is available to learn, Iâd say thatâs not possible. What does it mean to âexploreâ? 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. Iâve 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 youâve seen one spot youâve seen them all. Iâd argue thatâs not true, weâve only recently learned the moonâs poles are very interesting and we know very little about that. And Iâd 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 havenât 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 Iâd argue they donât 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 donât 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 donât 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 isnât.
Uli@sopuli.xyz â¨4⊠â¨days⊠ago
Well, now that we know whatâs out there, I think we should focus our efforts on putting a big sea monster into the ocean.
TheLowestStone@lemmy.world â¨4⊠â¨days⊠ago
Too easy. We need to put a sea monster on the moon.
MonkderVierte@lemmy.ml â¨4⊠â¨days⊠ago
The moon isnât that interesting, so we havenât done much with it.
Itâs a ball full of sharp and toxic shards that get everywhere.
On the other hand, thereâs immortal jellyfish.
Tlaloc_Temporal@lemmy.ca â¨4⊠â¨days⊠ago
It might be more accurate to say the average person knows more about what we donât know about the ocean than what we donât know about the moon.
We have a decent idea about what can and may exist in and about Earthâs oceans, but less about the moon; and most people assume itâs just a dusty rock too.
keepcarrot@hexbear.net â¨4⊠â¨days⊠ago
Everything outside of my immediate experience is densely packed squid atlanteans. (I feel like some people seem to genuinely think like this, which is distressing)
Taiatari@lemmynsfw.com â¨4⊠â¨days⊠ago
The blue planet 1 BBC documentary states that we know about the moons surface than ocean floor. The BBCâs Blue Planet 2 changed that to: we know more about the surface of mars than we know about the ocean floor.
So make of that what you want.

Norwegian fjords are freaking deep. When youâre on the shore of Sognefjord, youâre standing in front of a 1300m deep canyon filled with ocean water.
Merritt@lemm.ee â¨3⊠â¨days⊠ago
New anxiety unlocked.
supersquirrel@sopuli.xyz â¨2⊠â¨days⊠ago
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 past⌠but 1300m deep what???
âŚso 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.
_core@sh.itjust.works â¨1⊠â¨day⊠ago
They were carved by Slartibartfast, not glaciers.
SatansMaggotyCumFart@lemmy.world â¨4⊠â¨days⊠ago
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 youâre looking at almost 300 atmospheres of pressure and a whaleâs sphincter has to be strong enough to resist that.
disguy_ovahea@lemmy.world â¨4⊠â¨days⊠ago
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 the lungs contain into a small space and increasing internal cavity pressure.
kamenlady@lemmy.world â¨4⊠â¨days⊠ago
I think that also happens to humans, but without being adapted to it, itâs a one way squeeze.

Whales suffocate to death; they donât 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 canât breathe through their mouths; it goes straight to the stomach. The blowhole is the only respiratory tract.
Bonus bonus: a blue whaleâs throat is so small it could choke to death on a grapefruit.

Global warming has a slower effect on the oceans than in air temperatures, yet weâve 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 âhurricane alleyâ, and ocean heat has an exponential effect on hurricane strength.

disguy_ovahea@lemmy.world â¨4⊠â¨days⊠ago
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 gives a fuck after reading about the pee thing.
