I mean, it's an ecological dead zone, right? Nothing should be out there to threaten you, right? ...right?

had to get in a quick powernap ofc

That’s a very cool theory :)

That's is terrifying And I love it!

I recall orcas or dolphins using bubbles to surround and disorient fish into a tight ball. Definitely something I'd see the bioluminescence being used for as well.

@@OddOtter707 Yeah, using its own body to make a bait ball of sorts, and chomping down on medium to large sized prey. Or maybe making a display to attract a mate. Imagine two of those things creating a light show in the deep ocean during mating season.

@@Breathtaker5000 1 faxed i found ou it can grow infinetly as long it has the food space and other such stuff

This is actually most likely what happened, based on real life examples and the lore in the game itself, basic biology and nature itself would make this the case. It's why there aren't that many Sea Dragons either, tho they are also mostly suffering from lack of nutrition, they don't tend to reproduce often, the Sea Emperor also has a similar concept.

this would leave to a genetic bottleneck with a low enough population, like, there no way this thing eats enough to sustain itself

Very must true. Maybe there are still more alive in the deep sea.

@@DrSalvadorsSack Half the reason why most things go extinct is from environmental changes or destruction or a lack of nutrition/sustainability.

​@@gutembergcraft this is what people don't realize. I could believe though that due to their immense age and the size of the planet and distance between the population. That hundreds of years take place between each birth so there's still a large enough population to sustain a population without inbreeding

Possibly the biter leviathan?

I mean the mod version does

Well, the void isnt called the void for nothing. We know nothing about it and what could be there. modder already are on it to fill it with contend (wich i guess the dev's wanted to do for subnautica 3 and their MP part). The Garg and the few Adult ghosts we see can very well be small in comparison to what lurks there. Or the garg doesnt need that much food and would only need it to actualy grow further.

I love the idea and mostly agree with it but I do have one point to make which relates to another comment I saw, the garg is canonically the largest thing to have ever lived on 4546B so there would not have been reefbacks larger than it, however i love the idea of it hunting relatively close in size reefbacks and leviathans, and as another comment pointed out it may have gone extinct due to slowed reproductive cycles caused by it being so big and the defacto apex predator of its time causing it to not need to reproduce rapidly and eventually leading to it dying out, so I may try to learn coding and make a ancient reefback leviathan mod so i can use it with the garg mod

​@@bosi1665 what if it's carnivorous only in appearance? Would be pretty golden if it was a big cute snek that feeds on microorganisms and it's own stupidity

Very interesting thoughts! Wild to think about the reality of such a creature.

I dont think direct communication would be necessary for survival. Humans with split-brain syndrome are still coordinated.

I suppose that such creature would have more than a single brain. Many smaller secondary brain were probably present around his spine over the total length of his body. His eyes were probably adapted to find particular light signal in the darkness rather than granting a "clear sight". Its also very probable that this creature used echolocalisation to find prey over large distance. They were obviously nomadic in nature and were probably drifting around the ocean most of their time until they get hungry again or mate.

It also is a game where any adaption could happen cause it’s an alien planet so very possibly it could have evolved to have none of those problems

@@shaylist5298 form is function, that's true no matter where you are.

I was actually thinking that the Lost River area reminded me of a whalefall. You should look those up, they're actually really cool. It's basically when a whale dies, its corpse sinks to the bottom of the ocean, and it gets eaten by scavengers. It's a whole ecosystem that supposedly can last up to a century!

The dead zone doesnt stretch forever. I dont know if its canon, but even excluding below zero, there are multiple large islands you can see when leaving the planet, that look to be surrounded by shallower waters.

@@tree_addict280 Not forever, sure, but it is still the majority of the planet. Those pockets are few and far between.

@@ApoxyBreath I've seen those! Those are super cool, and ofc are the inspiration for both instances.

That's exactly what I was thinking when 1st entered The Lost River.

Also true in real life I'm pretty sure

How would that work ? I'm curious

@@terminator9489 It isn’t viable for big things to move around a lot, and so they barely move at all. Barely moving means low energy use, and since they’re big their meals tend to give them tons of energy. This equates to needing to eat very little.

@@terminator9489 what detectivewraith said. It’s a real world thing and it’s fascinating. Obviously it’s not years like in the game mostly few weeks at a time.

@@Succubi_bunnysome animals still can go years without eating in real life. Example is a crocodile or Galapagos Turtle,

Yeah, the garg definitely may have played a role in forcing the sea dragon into the crater

Was the garg alive during the sea dragon era? I know that you mention it in the video, but the pda on the skeleton suggests that its been dead so long that the earth changed around it. So, I would imagine the garg would have to have been around for a substantial amount of time, possibly even before the cataclysm, although im not entirely sure on that.

@@tree_addict280 both are milenial cratures, at least a early tipe of sea dragon had to survive the gargs to make the ones we knew. also, evolution takes thousands and thousands of generations to make really significant changes, and habing a life spam soo big doesnt help with that, most likely gargs didnt even have a chance of evolution to grow smaller as they reproduced extremely slow

a creature this size moving this deep would cause earthquakes every time it moves. Stop trying to find a logic to it, there is none.

@@solakendend5866 hey kid stop spamming

Like imagine you got to a point just for the pda to say something like Leviathan life form quickly approaching bigger then anything documented so far…. Thank you for your services And it just goes silent and then a cutscene play of it coming and getting you

@@ECHOKINGXD the bad ending

@@ThyLord-kv5bf but an ending that would be so sick to see

Actually, from my knowledge, isn't the Return of Ancients being developed by people from the actual team behind the game itself, or at least has them involved in some way? I remember hearing that somewhere, but I may be mistaken.

@@Going4Broke2528you might be confusing it with the VA’s of the game, the actual VA’s DID act in the mod though:), I’m very excited about it, still waiting 😢

Well yes but actually no. There is a Juvenile skeleton in the Lost River, but it’s not the massive main one you’re thinking of. That one is an adult skeleton, and only a third of it is uncovered. Nearby there is another Gargantuan skull that is much, much smaller.

Oh thats sad. Would've been cool if it was even bigger@@JC_Stone

@@JC_Stonewheres the smaller garg skull?

@@JC_StoneThe other skull/body that is in the lost river has nothing to do with the garg if thats what you are thinking. In fact there are theories that those skeletons are the opposite, the other one may have been a giant groundfeeder, around long before the gargantuan leviathan.

​@@tree_addict280no there is a second garg skull in the lost river, it's much smaller and when scanned it specifically states it's a juvenile garg skull

@@user-oq7xc5qp3ybut there isn’t ever a few hundred people present

@@tidxlu7595 not sure what you're trying to say, but the world population is around 8 billion.

Given the thing is implied to be sentient by the way it seemingly hijacks the PSA to tauntly ask, "Are you ready to die?" after the AI gives the Star Wars reference on the odds of survival, the reason why it even bothers is probably out malice and a sadistic sense of humor. It knows you're there, and it'll take pleasure taking anyway any sense of hope you might still have.

​@@RandoGruntWhere does this happen in the game? If you're referring to you being asked "Are you sure whatever you're doing is worth it?" I'm pretty sure that's just an automated thing.

@@Runic360 where does it say that?

​​@@dustincausey3344In the video it was stated that there are two Gargantuan Leviathan fossils in the lost river, which is correct. One is the huge one which only one third is exposed of and the other fossil is just a skull which is much smaller, but still huge. This one is the juvenile one

@@jaybarbieri8619 i dont see any reason or explanation in the lore for why they would re-visit 4546b, atleast not for a game-worthy reason. Although i do agree that it will probably focus more on the precursors this time rather than the character’s personal reasons. Seems like a promising game.

I think a bit like the Void Worms of the game rain world. A heavily streamlined form with many joints and fins for propulsion.

I'm about to sit down and do some math, I want to figure our a few things... mainly how much drag would a neutrally buoyant garg create, and their min/max drag when swimming. Even then, even swimming like a snake, the amount of mechanical force on its bones would be extreme.. I think it would be speed limited just because I think it would rip itself apart, and I'll do the work to prove it when I get home.

@@ATBatmanMALS31 They won't move much at all, big creatures tend to barely move in their life time, only to eat and even than they only go for easy quick meals and than they are back to sitting almost completely still.

@@ATBatmanMALS31 I never said I was and it wouldn't matter if I was or not, it's common knowledge that large creatures do not move frequently or quickly throughout their life to conserve energy and also to no overheat their body through their motions over a long period of time.

Neat, source?

@@user-oq7xc5qp3y source: I made it the fuckup

Wrong. The juvenile's skull is found elsewhere in the lost River, and doesn't have a ribcage exposed, unlike the adult. While the adult would be around 1300 meters long, the juvenile would be roughly 200 meters long

@@cartersmith8904good boy

The game already confirms and proves that to be impossible, while these creatures could probably last a year without eating, they have to eventually find a proper food source, to which there isn't anything in the void as the PDA scan suggest, which is also basically confirming that there aren't any Garg Leviathans around, only Ghost Leviathans and micro organisms.

@@raionshishi8290the void does eventually end, we know this, but also the garg lived so long ago the crater’s environment would have been plenty different. I would even say the garg may have lived around the time of the other skeleton in the river.

And also the deepest oceans are the void, which cant sustain ecosystems.

​@@tree_addict280 I mean game limitations exist

There is a theory that subnautica takes place on a huge volcano which kind of makes sense

A gigantic superpredator like this i doubt would stop moving. This is not to say it would always hunt, but like sharks, i doubt the gargs could stop moving, otherwise they’d die.😊

@@tree_addict280 well the reason sharks can't stay still is because of their special gills however 4546-b's inhabitants don't have gills I don't think so anyways

By contact... ...with water.

Flesh grazing is stupid and disproven

The only issues with that statement is that the Garg is an oversized electric eel; not only does its roar deliberate and damage prey because soundwaves travel faster in water than air and can quite literally rip people apart akin to a Sperm Whale, the electromagnetic nature of it makes it quite dangerous to touch. It uses that electric ability to drain your cyclops' power and also when it eats the Ghost Leviathans.

No problem! Glad you found it enjoyable

That's very true, the pda does say only micro species and leviathan class exist, what if it was classing the ghost as micro sized.

@@lizardlord6560 Highly doubtful it would classify the Ghost as a micro-organism by definition of each of those words and classes in general.

There is plenty proof. The garg species is millions of years old, and also it cannot live off of ghost leviathans and microscopic plankton, thats biologically impossible.

And the “other creatures” couldn’t be any bigger than the plankton, since the void cant support ecosystems.

@@lizardlord6560That is an absolutely stupid theory. The PDA classifies reaper leviathans as leviathans. It'd mark ghost leviathans as leviathans

Thanks! I’ve never tried something like that before, so I’m glad you liked it :)

Glad you enjoy em! I’ve got plenty more video ideas in the works : D

This is a literal gargantuan leviathan, you have to believe him

Thanks :D

It isn't unrealistic considering the fact that there planets with oceans of tar in real life, plus it is as different planet with a completely different ecosystem. The creatures have vastly physiology. You can't use how creatures evolve in Earth's ecosystem for a completely different planet.

​​@@masternabber5560 yeah but you can use it as a baseline, if the ecosystem is similar enough you kinda have to compare it to Earth since Earth is the only place for light-years around that can sustain life.

@@l0sts0ul89 No, you can't use earth at all, humans don't know everything about the universe. Earth isn't a baseline for everything, there are planets in our galaxy with acid rain, diamond rain and seas full of tar so clearly every planet has its own ecosystem that operates by its own laws. Earth is definitely not the only place that can sustain life, the universe is incredibly vast and ever expanding so if the cosmos can generate a sustainable planet like Earth as an example then there are clearly other hospitable planets. The galaxy humans know is grain of sand that blows against cosmic winds, it's hard to comprehend how vast the cosmos is.

@@masternabber5560 I mean, there might be different ecosystems, but we all use the same physics.

@@Neion8 No, that's just your assumption about using the same physics.

Hey Its me but From another Account

NOTHING killed it, it died to a cave. it shares ancestory with reapers. so they seem to likely, be both dumbfuck shit for brains. there was no predator that killed it. it probably got stuck in a cave while chasing ghost leviathans around, and it died. its proven that a cave probably collapsed on it, because most of its skeleton is covered by debris, it probably got injured from falling, and a ton of ghosts/other leviathans, came to feed on the corpse till it was bone, and the rest of the corpse decayed. likely it died below 20 years ago, since bones decay after 20 years.

@@user-oc3sp4lh8o PDA entry clearly states that there was no cave.

​@@user-oc3sp4lh8othere was no cave

Watched the video, That intro went hard, and I LOVE the speculative biology and life cycle of The Garg. I've always wondered how such a spectacular titan of biology ended up entombed in the lost river, whether it be by entering willingly or the world growing and enclosing around them as time passed.

Glad you liked the into, I’ve never tried something like it before, so I was curious what people would think

Welcome aboard! 😁

Thanks lol, halfway through making it I was wondering if I should just scrap the whole thing

Maybe I’ll do a video on the mod lore once it fully releases 🤔

probably it getting stuck in a cave, and something might have struck it during that, it probably died of starvation. it probably didnt have enough nutrients to sustain it, and the scar? from possibly debris from some caves underwater. or another garg killed the juvenile.

@@user-oc3sp4lh8o the skeleton isn't juvenile. There's literally nothing that points to that. On the other hand, level designers do imply that it is adult.

@@user-oq7xc5qp3y im pretty sure when you scan it the pda will tell you that it's a juvenile

​​@orrie1911 No. The large skull is not a juvenile. However, a smaller skull, is indeed the juvenile, the smaller skull is somewhere nearby, can't remember exactly where though

@@orrie1911 can you give direct quote? PDA entry is on the wiki by the way.

Thanks ☺️

To Do NOT want to know what the hell else is out there if a Ghost is a little bottom feeder.

That would be so cool!

"since the two skeletons are big, but still juvenile" - lie.

@@user-oq7xc5qp3y could be, i dont know full, i thought it said in the pda entry that they were juvenile, but they could be fully grown. But you have to think, a planet that big with skeletons that big, you really think that whole species died out?

@@itsbojac5579 pda doesn't say anything about it. Also, there is a smaller skeleton, implying that bigger one is adult.

@@user-oq7xc5qp3y My god, here you are yet again, on another comment. "implying that the bigger one is adult" - lie. There is nothing implying one is an adult, just that one is bigger than another. YOU are making that assumption. Since you're acting like you know literally everything about a video game that was NEVER stated, I'll take the time to point out that you're talking out of your ass and don't know a damn thing. It's all made up bullshit, and you're running through these comments like you know absolutely anything. Fun fact for you little guy - there aren't simply 2 sizes to an organism. Something isn't born at one size, and then one day just transforms into another size. There is a slow growth from birth until full maturity, meaning every size in between exists. If 2 humans die, one at 4 years old and another at 12, that means one is a juvenile and another is an adult? No, it does not. It means they both died, at different sizes. The logical stupidity in your comments is just painfully annoying. Acting like you know shit about made up theories in a video game is the lamest thing I've ever seen.

Glad you enjoyed it :D

It makes no sense why it would still live, let alone in the void. The mod is cool dont get me wrong, but it just doesnt make sense.

I may be wrong, but I believe it comes from a specific piece of Subnautica concept art showing the Cyclops being grabbed by a huge mass of tendrils. Thats probably where the idea came from but I'm not sure. It could just be because tendrils are off-putting and somewhat scary on their own.

The gargantuan is complete speculation anyway, not even the name is said in the PDA, let alone its appearance. The only thing that we know mostly for certain is its size and what it would have done.

could be, it probably fed off ghost leviathans, since those things are the only things that it could feed off. its eyes are n the side of its head, like a prey animal. it probably fed on ghost leviathans, like a whale feeding off or on krill. or they maybe lived off of eating other injured gargs/juveniles, since they could probably eat a garg with their massive size, not to mention how big gargs are, feeding off eachother would have probably provided them years worths of food.

"Its sheer size would have prohibited it from entering such an enclosed space, suggesting the geography of the planet has shifted around it over time." PDA entry, that describes gargantuan fossil.

@@user-oq7xc5qp3y That entry is old, from before the river was finished. It would absolutely have fit coming the other way, and it's even about a kilometer from the bulb zone adjacent entrance to the river.

@@Xahnel Oh, so that entry is old? So developers updated the lore of garg? And changed PDA entry to a new one? May I see this new entry?

@@user-oq7xc5qp3y First off, the PDA entry is pure speculation. Secondly, there are multiple entrances and the intended entrance is the one that leads from the degassi habitat, so _that path_ would be impossible. But you can then _follow_ the path behind the garg, and see that it's more than wide enough. _Third,_ I would like to point out that despite being a volcanic _mountain,_ shaped vaguely like a cone with the highest points in the center and the lowest points towards the edges (excepting the mountain island), the playable area of subnautica is called a _crater,_ which is shaped the exact OPPOSITE, with the lowest points towards the center, and the highest points being the ridge that surrounds the impact site. So let's not pretend like the PDA can't be _wrong_ on topics of geology. A volcanic plateau mountain with caves is not a crater. 4th, considering this _is_ a conical volcano, the geology violates the general physics one sees in building up a volcano over time. The mountain of land above the skeleton could not have formed without magmatic activity. There is no indication the garg was built in any way to be immune to lava flows. The creature could not have settled there, fossilized, been buried by a volcanic eruption, _then_ uncovered, and finally created a whalefall microbiome. That violates physics. Bones don't handle lava, period, which means it's not buried post eruption, and a fossil of that size would not have survived so marvelously intact through a violent enough eruption to deposit that much mass above the caves. Nor could the skeleton survive the erosion of the cave that would have uncovered it. Fossil is more fragile than the surrounding rock, it would have eroded _faster,_ not slower. And yet the skeleton sits almost completely exposed, as if it died, settled to the floor, and the world built a cocoon around it. The formation of the caves and placement of the garg skeleton out in the open indicates the cave must have existed when the Garg died, trapped inside it. Because it literally could not exist in any other way on a volcano. And here is the kicker! There is a dead end location deep in the lost river that has a smaller SECOND gargantuan leviathan skull! And you can trace portions of the ribcage of the bigger one to the lost river intersection. Why would the cave follow the body? Why is there more than one? And the final piece of evidence, a microbiome that evolved around decay. Just like how whalefalls and elephant graveyards create a microbiome of the dead being recycled by scavengers, the lost river is a microbiome of scavengers and predators. A microbiome the Garg created with its death, the scent of decay drawing critters in to feast in a self perpetuating cycle that has lasted 3 million years. Now, tell me, how does a fossil with no meat on it cause the formation of a whalefall microbiome? No, based on the evidence, the devs clearly have no idea about geology. They can't tell the difference between a mountain and a crater, they don't know how volcanoes form, they don't get how cave erosion works, they don't know how fossils work, and that all, combined with the microbiome, creates a giant mess of wrongness in the Garg skeleton placement. See, the Garg is a setpiece. They set the piece, then tried to justify it, and failed, utterly.

Nothing tells us that garg stops growing, yes. But, this isn't an argument to consider it true.

No, mod devs gone nuts and increased it's size by four times.

it would have been a keystone species with very few members but a large impact on the ecosystem. you’re right, there probably were only a couple thousand throughout the planet, given their size and the behavior of aquatic predators. territory is a huge factor. this monster would need a large, large amount of territory to itself for growing and hunting, which makes the population even smaller. tbh… no wonder this thing went extinct 😭

yeah, likely there can only be one within the crater/void at once, however i like to imagine theres an area beyond the void, so unbelievably dark and deep, even gargs ont dare to venture there.

@@user-oc3sp4lh8o you like to imagine a lot of things.

Truly the most terrifying foe 💀

That would be awesome!
