The Gargantuan Leviathan - Subnautica's Extinct Colossus

The gargantuan leviathan was one of the most fascinating creatures to have ever lived on planet 4546B. Its status is nothing short of iconic, yet few seem to know much about it. Today, we’ll turn back time, as we explore the story of a creature whose sheer size allowed it to rise through the ranks, while cementing its eventual downfall.

Given the size of the gargantuan, it could also have had a slow birth cycle. As an example the Greenland Shark, which lives in very deep cold environments and Is one of the biggest sharks of its kind. But it reaches sexual maturity at the age of 150 and higher which makes its reproductive cycle extreamly slow, although due to its slow metabolism it does move extreamly slow, but at the same time they can live for an esimated 500 years or more. Gargantuan Leviathans could have also been assisted in its downfall by low birth rates caused by the leviathans evolution to be so large that most animals would not mess with them at most ages, so the necessity to make more young quickly and in higher numbers not necessary.

[@raionshishi8290]

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.

[@gutembergcraft]

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

Well, the void isnt called the void for nothing.

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.

[@bosi1665]

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

[@Jacob-df5hr]

An issue with an animal exceeding a kilometer in length is that it will run into issues with lag in its nervous system. Myelinated nerves, which are the fastest nerves and analogous to an insulated wire, can propagate a membrane potential at about 150m/s. It would take almost 7 seconds between a Gargantuan Leviathan's brain telling its tail to move, and the tail actually moving. It would have to have had hundreds of nuclei in its spinal cord to take advantage of reflex arcs to produce anything close to a coordinated, effective swimming motion, but it wouldn't have been close to agile. Alternatively, it could have been an ambush predator, spending much of its time coiled and using a number of rostral appendages to accelerate its head towards prey while the rest of the body stayed more or less stationary. It likely would have been blind, as the sheer enormity of its wake turbulence would have caused a silt-out in any environment where it would have been worth it to have eyes. It would have to have had a highly developed sense of proprioception to avoid mistaking the distal portions of its own body as prey. Or sapience. There are clear advantages to being big. The advantages to being _that_ big are less clear.

[@BHM_Productions]

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

[@Nathann-by2jb]

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

[@trigz8626]

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.

6:33 I would personally suggest that it would go months to years without a "sustaining" meal, only snacking on smaller creatures. Much like how many reptiles do here. For example, crocodiles and alligators have been seen going upwards of 12 months without food, and was likely what dinosaurs did aswell. I believe this is what many super-apex-predators such as the gargantuan leviathan would have done. also i dont believe you mentioned it, but my personal head cannon is that the sea dragons once lived much higher than where they do now, however conveniently had the right body structure and abilities to survive in the magma zone once forced there to survive the garg

[@Breathtaker5000]

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

[@tree_addict280]

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

For anyone whose ever played Monster Hunter, the Lost River essentially being an ecosystem grown around the corpse of a Garg, is very reminiscent of the Rotten Vale in Monster Hunter World, which is an ecosystem built around the corpse of a particularly large Dalamadur, which is funnily enough also a gigantic serpent, albeit one that isn't aquatic. While on the subject, it is worth noting that, since the crater in which the game takes place is such a small fraction of 4546-B, that it is entirely possible that the Garg exist elsewhere in the deadzone, since it was stated that the only lifeforms out there are microscopic or Leviathans, and therefore if everything elsewhere on the planet is much larger, food may be easier to find.

[@ApoxyBreath]

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!

A big problem with such a big creature is neuron conduction delay. It will take anywhere between 10s to 1 minute for signals to propagate from the brain to the tail, thus making it impractical to perform any complex movement. They will likely have a segmented body and distributed brain system and mostly lure their food instead of actively hunting them. That is unless creatures on 4546-B developed some sort of optical fiber nervous system instead of the electrochemical nervous system found on Earth, which is quite likely given the ubiquity of bioluminescence.

If we're gonna examine this from a biological standpoint, it seems to me that the gargantuan leviathan is unrealistically long. Its skin would have to be insanely thick and durable / be capable of shocking (which is locally I suppose, otherwise charge is easily lost) / poisonous, since otherwise it would be sort of defenseless for most its body. Furthermore, as the gargantuan leviathan is a snake-like creature, the propulsion in water would mean having to move absolutely massive amounts of water.. and is therefore at best quite slow.

[@masternabber5560]

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.

[@l0sts0ul89]

​​@@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.

[@masternabber5560]

@@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.

[@user-oc3sp4lh8o]

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.

[@ayaannair2447]

So I've always subscribed to the theory that the Garg primarily functioned as an Ambush predator the way Angler fish and alligators do. My main reason for this is the luminescent tentacles and the elongated jaw. Assuming jaw muscles similar to an alligator, the Garg would have only needed one bite before dragging and death rolling prey into submission and eating them. It also proposes a theory for why it was so big. If its ancestors were all ambush predators, their pool of prey would have been much smaller than the other giants in the ocean. Over time, size would be the most favored gene as all the smaller creatures would be starved out, eventually leading to the garg. As for hunting strategies, it would simply need to have an open mouth with luminescent tentacles floating inside, and wait for prey to come nearby before chomping down. alternatively it could spread out these tentacles allowing it to have a much larger net. It would also give a reason for it to have multiple eyes, even though it does not make any sense. The lights along the body could be a warning to competing predators to stay away by illuminating the entire body for display. There would be no better warning than showing just how large it is. Most predators would never wager their lives on this meal no matter how substantial, effectively securing the gargs safety

[@FoxBoyWithBushyTailAndEars]

How to know something is big? Most creatures are named after a part of them both in game and real life with examples being the bone shark and peeper. The gargantuan leviathan is so massive its name is just two prefixes for large and yet so fitting, no one notices.

[@somtingabawh]

You are one of the KZbinrs that makes the highest level of videos but just not getting the support that you deserve

[@Xahnel]

My take: Deep sea gigantism indicates that the larger a creature is, the less energy it costs to operate overall. Life that would evolve to support leviathans like these would not have started in the inky black void. Life starts in locations of abundant energy. There were likely many shallow places where sunlight and primordial ooze gave way to first simple phytolifeforms, then microscopic plants, then herbivorous bacteria, then carnivorous, and thus the race was on. The most important factor here is the length of the juvenile. It most likely lived by circling the subnautica volcanic plataeu, and occasionally hunting leviathans in the deep biomes near the edge. If it wanted, it could prop itself up lengthwise against the plateau and just sat with its mouth open, like a snapping turtle, bating its food in by wriggling its tongue. Or, it would occasionally cross over the shallower sections, pluck a reaper (the best eating on the plateau, its body mass being majority flesh). What is very clear is how it died. At some point, one of its prey critters pulled an absolute gigabrain move, and fled into a cave system. Since the Garg and Reaper both likely shared an ancestor, it didn't have much brains. It dove in after, thrashing and crushing its way through the cave trying to reach it a food, until it finally became stuck. Based on the orientation, it used the lost river cave entrance in the bulb zone, north of the Aurora and east of the mountain island. I would guess it was hunting a Ghost, since the natural life cycle of Ghosts demands they re-enter that cavern to lay eggs. It might have retreated to ancestral waters, someplace that represented safety to the Ghost. It's death would have been slow and agonizing, and the whalefall of a kilometer long creature created a permanent macrobiome.

[@user-oc3sp4lh8o]

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.

[@Xahnel]

@@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.

[@user-oq7xc5qp3y]

@@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?

[@Xahnel]

@@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.

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.

Only thing missing is that, due to their slow metabolism, the rate of their growth would likely make it need decades or even centuries to reach full size, or perhaps they never stopped growing.
