I always wished there was some sort of animation where a reaper comes after you over a chasm into either the blood kelp or grand reef and just before it gets you a sea dragon snags its tail you you watch the reaper get dragged into the depths never to be seen in the flesh again... it would be an awesome reality check that there is always a bigger fish

I usually find voices that sound as young as yours incredibly annoying, and yet yours is incredibly soothing. Then there is the fact is that these are actually really good theories. I am honestly impressed.

I also did forget to mention: One way the Sea Dragons likely survived is by traveling through the corridor that connected the Inactive Lava Zone and the Crash Zone. Sea Dragons would have traveled through this in order to hunt Reaper Leviathans and other fauna. This corridor was covered up when the Aurora crashed however which may be another cause to the Sea Dragons recent decline. Another thing that could contribute is that since the Sea Emperor was able to survive for thousands of years and since the Sea Dragons is related to the Sea Emperor, the Sea Dragons life span could be incredibly long, possibly thousands of years which would allow the species to survive.

Nobody: Speedy at the end of theory videos: maybe it’s a COMBINATION Nah but seriously that’s cool that you consider all the possibilities

I really hope you don't end up just giving up on youtube cause I flippin love watching your video's.

It’s amazing to see how subnautica went from being a fun underwater game to people studying the species of the animals and it’s food chain and how it survives I love the content keep it up!

Dude, no offense, when you talk you remind me of a young Game Theory. Legendary. Let’s get you to a million subs.

Since the sea dragon no longer has access to reaper leviathans to kill and eat, they will most likely become completely extinct.

reaper: viben sea dragon: I’M MAKING LEVIATHAN AND CHEESE AND NOBODY CAN STOP ME!

The reason that leviathans, in game and in real life, are able to survive is that they don't actually need to eat as much as you think. Look up Kleiber's Law. (This is why the deeper you go in Earth's ocean, as there is less food, there are also more large creatures such as the giant squid because they have a metabolic advantage)

Where do you get this information? Loved the video Btw

Seadragon:(Father it's me, Micheal) I should be dead, but I'm not. (edit) Yo, what!? How did more than 200 people like this?

Riley Robinson likely also would've caused a massive population boom of literally everything with the near elimination of the Kharaa bacterium, so if a third part of Subnautica occurred after Below Zero, taking place in the crater once more, it's entirely possible that if the Devs wanted to be realistic there could be a stupid number of these, and everything else, due to a likely jump in population and biodiversity.

Another theory to keep in mind is deep sea gigantism, many species in our deep oceans can go years without eating despite the massive size of them for some odd reasons. Due to the reapers being the highest population of leviathans it could easily be possible that their low energy movements combined with the molten minerals in it's environment could lead us to speculate that the sea dragon might only need a single reaper to survive for a very long time

Cool video, I always figured that their high body heat helped keep them from getting infected as often.

"It's big, its dangerous." (The definition of Subnautica) -JUST chill

Your videos are pretty on par quality wise with older, larger creators I've seen and videos like this I find really intriguing and have really interesting theories and discussions I'll look forward to more of your future content, and think you could definitely build up a good platform if you keep it up Definitely subscribing :)

I love your theory videos! I fell back into the Subnautica rabbit hole again and you’re super entertaining and your videos are high quality!

My question ideas that I would like answered but I'm not sure if they can be Does the Reaper's echolocation actually real? (like would water interrupt) Could the seamoth and PRAWN actually open and close that quickly and easily to allow entry? Is it possible to get any information from the scanner? (in its data entry it talked about using a certain type of wave) Would the Aurora only cause that little damage to its surrounding area after the crash? (terrain and radiation) Is the Scanner Room's Cameras range long or short? (I've always thought they were remarkably short for atleast 2.5 million years in the future) And my final one is will Unknown Worlds ever provide updates to the original Subnatuica?

Nobody even talks about how the adult ghost leviathan only eats microscopic organisms

My Theory is they’re too strong to be everywhere so they lowered the numbers for plot reasons

Not even gonna lie I hate listening to my teacher's and stuf but for some reson I love listening to you talk about theses things... 😂😅

I love the fact that even though you are young, you are doing what you like and doing it with professionality. Great job mate!

These vids are so well made, I’m surprised you don’t have more subscribers! You’ve earned mine Ps, do you have any ideas for projects or things to do after you beat the game? I’ve collected all the eggs and built a base, but I can’t bear to stop playing this game

I just figured that Kharrar can’t survive as well in the high heat environment of the lava zones. That’s why the Emperor Leviathan is held there , to keep its biome “pure.”

Just found your channel and love it to bits subnautica is one of my favorite games Love these so much

I love this channel Its so fun hearing theorys that are good and have many possibilitys

i like how dedicated you are to the channel i can tell from ur production quality

40 year old guys trying to explain subnautica: aliens and fish like to Harass you . Speedymouse: *explains secret of the world in 2 seconds*

Its stated that the aurora covered a hole leading directly to the lava zone which sea dragons would often come out of to drag reapers down into the lava zone, burn them alive then eat them

One of the reasons that this guy is my favorite KZfaq or when it comes to theories on video games is the fact that the way he words sentences is the way I word things in real life. I am seriously not kidding, the way he’s talking in this video perfectly reflects how I would interact with another human being.

really cool video essay. keep it up, proud of you

Great video as always. Made me subscribe!

These videos you make are really good keep up the good work

Sea Dragon Leviathan: Survives The Kharaa outbreak Enraged Ryley : fine ill kill them myself

You know for an advance alien race I’m surprised the Aliens in subnatica didn’t take into account the parent of the sea dragon leviathan egg they stole wouldn’t come after them.Especially since this species is so close to extinction

Gotta say, man; heard your voice at the beginning of this video, and thought to myself "greeeaaaat! Some kid's weak-ass Subnautica video!" Boy am I glad I was wrong. Seem like a pretty smart dude! Keep up the good work, bro!

Man your videos are addicting I can’t stop watching them and it’s 2am

You would think that since the precursors were in the inactive/active lava zone, that they would have better defence against those creatures, especially with their technology.

Bro i dont watch your videos that much but when i do i really enjoy them and you just should have alot more subs

Very eloquent theory and analysis, great vid! I admit I was sceptical at first, I was wrong.

Man I envy you. I used to strike keys randomly in games at your age and get excited only to see making something move the way I wanted them to, let alone following stories and understanding instructions. I'm judging by your voice tone of course, yet you're able to assess things in a way that's way too mature for that age.

Man, you have so many good theories

Why not just spawn more in? That would take care of the extinction problem.

Bro how old are you? Your videos are really good, keep up the good work and I bet you’ll be huge! That said the only reason I don’t kill them is only because it’s time consuming, I otherwise tend to kill all the leviathans that attack on sight.

I’m guessing that Speedy Mouse is most likely 12-14, and yet he is bringing up topics and making theories that most observant adults would pass over. My man you are smart af, and I can definitely see you going far

Guys, Aurora is shaking as hell. At someday, it will fall to the Void, and the Seadragons will get back their corridor. Plus, as we all know Alterra has claimed the planet, so I think they can pick up parts of Aurora, trying to rebuild it, or use for something else. This vencile cost more than half of other Alterra spaceships, they cant just leave it there!

Are you planning to do Below Zero videos after it comes out this month? Love these Subnautica vids!

Ok so here’s my insane theories: To survive, what if similar to plants photosynthesis, the sea dragons managed to somehow adapt or had always had the ability to absorb thermal energy and survive through that and that’s why there are so few, they can’t reproduce with their energy basically only coming from thermal with little vitamins or protein and the like. Also how they survived the kharaa is through the fact that they are related to the sea emperor and although they can’t protect others from kharaa, they can protect themselves

I'm with the "Don't kill seadragons", Because im a seadragon.

You know how I thanked of this and you just answered it thanks

Quality is definitely not bad... Keep going

Finally there’s a channel that can answer my subnautica thoughts

My guess would be that the sea dragon leviathan naturaly prayed on reaper leviathans. The biggest entrance to the lost river and the lava zone is just at the endge of the mountains where reapers have their territory. My guess would be that the crash of the aurora did destroy a part of the safe shallows where the reaper leviathans had their breeding grounds. Like sharks they could wander over there just to lay eggs and the young reapers would have enough pray in the safe shallows to grow until they migrate to the deep waters. Due to the aurora destroying that breeding ground the reapers don't have their breeding ground and that could be the reason why we don't see reaper eggs or young reaper leviathans. Since we don't see other bones in the lava zone I doubt that the sea dragon levathians pray on other big leviatans. And the only skeletons that we find in the lost river seem to be quite old. Maybe they prayed on one of the other leviathans before but since they survived for a long time after this I guess that these creatures where able to adept to the reapers being their new food source. I like your theorie that the sea dragons can consume lava and rocks. My guess would be that they get their minerals through that source of food but not for calorie intake. Reapers seem to be very strong and muscular so they would be a good source of protein and fat. I think the food is not the biggest issue for the species. Seeing that there are only 3 specimiens in the crater remaining (and one that died during the attack on the facility). I think that breeding is a big problem for the leviathans. With such a small population in one area I doubt that these leviathans are not related. They might be a species that only lays small clutches of eggs and protects it's young. Which is supported by the fact that the sea dragon mother came out of her natural habitat to find her eggs and rescue them. Seeing how small that population is i guess that they might be living in family groups and travel in order to find partners and breed, coming back to their hatching grounds in order to lay the eggs and hatch them. Since the ghost leviathan near the entrence of the lave zone shows no fear of it or injuries I think it's not obsurd to think that those species peacefully co-exist. While traveling the deep ocean sea dragon leviathans would probably not have a problem with the ghost leviathans and the migration to find mates would be possible. The problem might now be that the breeding circle is quite long for that species. It might even be possible that the two leviathans in the lava lakes are the children of the leviathans living in the inactive lava zone. Due to the long way for mating and the precursers stealing a clutch of the eggs the species might have a harsh time populating. And since they seem to live in vulcanos and prefer the heat there might not be a lot of suited envorinment around the planet for the species. I like your theories, but I don't believe that the sea dragons main food source is supposed to be a species that did go extinct and not the reaper leviathans. I do agree with the fact that these creatures probablc consume lava and rock for nurishment and mainly minerals. As I said I think the main problem for the sea leviathans is not the food source but rather the mating process. Good video will defenetly check out more of yout videos. 👍🏻 Maybe you should go in the direction of biology since your theories where pretty good.

I think that the Sea Dragon Leviathan species survived off of Lava Insects. Yes, Lava Insects. You see, the creatures you find in the lava zones, the Lava Larva, is referred to as being in the larval stage of its species, so presumably, it could get much bigger than it is. The reason the larva never mature is probably because of the same reason eggs never hatch in the wild and have to be relocated to an Alien Containment. How they are still able to reproduce, I am not sure, but it could be a distinct trait for the species, maybe have been introduced by genetic modification from the Kahraa Bacterium. So the Sea Dragons probably ate Lava Insects until their extinction, Reaper Leviathans, until the Aurora presumably blocked off the cave entrance the dragons used to surface, and today, they rely on nutrients from magma, Crimson Rays, Lava Lizards, and maybe Lava Larva, Magmarangs, and Red Eyeyes.

It's also interesting how they only have 5000 health, the same as a reaper.

Hey that’s my idea!!! That’s so cool!!!

Wait a minute... You are a MESMER! Your voice draws me in...

What if the Sea Dragons hunted Research Specimen Theta’s species? It’s big enough to provide a lot of food, and I assume the Sea Dragon would be able to kill it with it’s fireballs, and maybe crush it’s bone?

My theoru is that since the sea dragon is related to the sea emperor it also produced an enzyme similar to enzyme 42 and just didnt eject it, allowing it to survive the bacterium and help its digesting the rocks.

I think that sea dragons can or could likely also be found inside deep sea trenches and smaller volcanic craters in the open ocean, and their historic food source would have been the giant plankton eaters in the sea like ghost leviathans and young sea emperors, since they could definitely provide enough food to sustain a species that large the crater might have been a nesting ground for the species, meaning the three could be the other young of mama dragon, who hatched and have since reached adulthood without a parent and become trapped in the lava zone with no way out (made even worse by the Aurora's crash)

I think it mentioned in an old pda entry that the sea dragon would drag reaper's to the depths to eat them. But I think it was cut in an old update

Why this has so few likes 😢I love your content keep going ❤️

I found a PDA entry that said all infected specimens were terminated, except for 1.

i want to add that maybe because the sea dragons lived in hotter climates it might kill the bacteria and make other species go lower to fined uninfected prey but after the creatures adapted to the Kara they would be less creatures down there so the sea dragon species slowly reduced to 3 but even is they reproduced the probably lay 1 egg at a time suggested by the precursors taking only 1 , if not the case the sea dragon went after them immediately so it was probably only the 1.

My theory I think it is possible, but rather unlikely, that the dragon feeds on the precursors that did not successfully evacuate 4546B that still survive to this day and are trapped in the lava area.Maybe as attempts to end their own suffering they feed themselves to the dragon to feel the sweet release of a quick death by being eaten, instead of a long drawn out death from starvation.Either this or Some of the aurora, or even Degasi, survivors made it down somehow to the lava zone, only to be either eaten by the dragon or trapped down their in one of the precursor structures, suffering a similar fate to the earlier mentioned precursors that failed to evacuate in time. Great vid as usual Mouse, just subbed.

When you scan the reaper skeleton in the lost river it says that it is recent and gets brought down by larger leviathans so that theory is spot on

I think you might be aware of this but there was something called the hell hole I’m pretty was it’s name. Anyways it was a hole in front of the Aurora that went into the inactive lava zone. Which could help to explain the sea dragons feeding on reapers at that made it much easier to travel to and from the lava zone. But it was removed so who knows now.

Underrated content

There are a lot of mods witch add a rare spawn in the dunes and the crash zone of a Sea Dragon

I mean we do know, that the was a hole down to the lava zone. It got removed if i remember correctly, but now its just the theory, that the Aurora blocks the hole so the seadragons were able to hunt at the surface, but arent anymore now, so they basically are screwed now.

I have a few ideas, Is there a planet in real life that is similar too the planet you are on in subnautica? How did is sea emperor still alive? What are the warpers technically? How did the Khaaraa virus spread? How was the planet before the khaara virus? What are the backstory’s behind the items that are locked in the cages (I think it was where the portals were)

a little fyi changing an organisms feeding pattern is really hard, if not impossible. the few exceptions we know about are those from animals that are already partially omnivores. So if a claim like "the bacterium mutated them making them able to sustain on new material" means that somehow the bacterium would need to alter the entire DNA code of the host and doing so would result in death or in cancer but more often death.

The asmr makes his voice soothing

i have a theory perhaps the reason the precursors took a sea dragon egg is because they are immune to kharra bacterium. and where trying to study them to figure out how. and if this was true, maybe sea dragons actually eat kharra bacterium from time to time, and also other prey. but this is just a theory i meant "what if they are immune to kharra" i don't understand why they would just go steal their egg. they probably had a reason.

Nice vid

Imagine this You go out of your life pod and you’re searching for food and resources to build more things but then you hear a giant rower in the distance than you see tentacles and then you see a sea dragon pulling down reaper all The way down to is lava domain

This man hella under rated

anyone think about how in the Subnautica universe, the Gargantuan Leviathan would probably be alive right now because the game takes place thousands of years from now?

I'm confused about why the sea dragons are in those lava caves along with the titan leviathan and those other leviathans found in the labs.

Ngl the sea dragon levithan sorta could be a branched path of the sea emperor levithan.

*Ryley Robinson fucking lands with his prawn suit* "Who said they haven't?"

I feel like the 1/3rd of lava/rock is what it's lava barrage is and it's adapted to use this to make it mine to heat and as a attack

My theory is that the sea dragon leviathan absorbs heat from its surroundings, much like the yeti crab that lives on earth. Here’s a link to the wiki page for the yeti crab - en.wikipedia.org/wiki/Kiwa_hirsuta

Hey Speedy Mouse just so you know there used to be a whole between where the Aurora crashed and the lava Zone connecting them where the Sea Dragon Leviathan pulled Reaper leviathans down into and boiled them and the Aurora landed on it so their food stopped a little bit after the Aurora hit

The sea dragon by the primary containment facility probably lived from kahra because the sea empress is producing Amazon 42 through the walls and it's coming out and curing the sea dragon

How do you only have 8k subs thats my only question

Hey haven't died out yet since I haven't made it down there with the Prawn Suit, a few batteries for the repair tool, and a lot of patience.

in the beta the way u got to the lava zone was a big hole next to the crash site, the dragon will swim up and take the reaper down but now the aurora block the hole so after the events of Subnautica they most likely died out

You are very good at what you do just saying.

You seem really young but i love the vids and i think they found out that lava or magma has ALOT of calories so maybe its eating that haha

You should make a video about pre out break 4546B

JFJ: *Sees the title* Also JFJ: Howa bout we change that

Some reptiles also only need to eat rarely so the sea dragon may have survived by eating minimally and very rarely.

What do you use for editing?

The calming voice tho

I literally know every bit of lore of subnautica cause I have studied it but I can't study for a school test

Sea Dragons are likely Cold Blooded considering they are reptilian and live in hot areas which dont require warm blood, and cold blooded creatures require much less food than warm blooded creatures as producing your own heat requires a constant supply of energy. Also because of the heat in the area and the flame breath its likely that creatures can end up being cooked when attacked by a Sea Dragon because of them ya know, breathing fire, and cooking food is much easier to digest, in fact, when an animal eats something most of the energy is used in digestion leaving just enough to survive on, however because cooked food is easier to digest more of that energy can used for other purposes. TL;DR Sea Dragon is Cold Blooded and the heat cooks food meaning they require less food bc cold blood and food gives more energy when its cooked

I think I'll eat a couple reapers maybe a reefback and then pass it down with a cup of lava.

"likely the reaper and dragon left their natural habitats in search of food where they inevitably met" pda directly says that the dragon leaves the lava zone to hunt, its not that they would both have to move or adapt the sea dragon just does its thing
