The Warper, unlike the other creatures in Subnautica, is a cyborg life form which can open a teleportation gate. What makes the Warper dangerous is that it can shoot projectiles that can cause lots of damage. It has a purple, cloak-like membrane that covers its translucent pale blue body.

Sea Treader

The Sea Trader may perhaps be a defensive creature, which makes it more dangerous when threatened. Its body consists of a large torso with long, double-jointed back legs. If you try to swim in front of it, the Sea Treader will automatically attack you.

  1. one the sea treader is super easy to avoid and not that strong all it dose is 40 but who cares is so slow and another thing the Stalker is tamable and not that strong compared to the Ghost Leviathan and why is the ghost leviathan not on this list its more dangerous that the reaper!!

    1. I agree big time, honestly, this also was made a bit ago. Maybe they didn´t update it soon enough or took it from their own knoledge.

    2. I know right they shud seriously add the Ghost to this the Ghost is actually the second, and everyone thinks the ghost leviathan is weak and this youtube video said that the reaper is able to kill a ghost but the ghost is more powerful.

  2. and the Drooping Stingers do 50 damage in 3 seconds and you might say its easy to avoid if you swimming away from something you could run in to one and that could be game over and plants are creatures to. that is my statement and i am the same person from before.

    1. i worked really hard to get the seamoth and the first time i go really far from base i ran into my first reaper leviathan and it destroyed my seamoth 🙁

    2. wont put in my email or name but i think the most scariest one is the crab squid because that triggers my arachnophobia big time


  4. What about the Sea Emporer, although it isn’t hostile now isn’t it supposed to be agressive, correct me if I’m wrong.

    1. I know that this might sound stupid, but can you kill a leviathan? Or can you only attack of with the stupid survival knife?

      1. You can kill them. It takes between 75-100 knife hits with the upgraded version of the knife so probably 150-200 with the regular knife. The best way to fight em is to jump out of your vehicle and use the gun that slows things down. Get a tiny shot off when it rushes you, then go straight to its side and shoot a full charge into it. Swing 15-20 times then shoot it again. Repeat until it is dead.

  5. Me and my friend have a world and we somehow escaped a reaper… Buuuuuuuut our seamoth was destroyed. We haven’t been playing for that long but we discovered a lava biome. If you know how to get the multipurpose room reply to this.

      1. the floating island?
        if it has a degasi seabase it’s the floating island it has floaters
        ALL under it anchent floaters yes!

  6. OK the ghost leviathan is definitely the 2nd most dangerous leviathan (only behind Reaper leviathan), let me explain why.

    -it has 3000 more health than the reaper leviathan

    -It does more bite damage than the Reaper Leviathan

    -It also has a more strange/random hit box, so it’s harder to freeze with the stasis rifle. So killing it is actually harder

    -It’s shriek sound is creepy as hell, even worse than the Reaper IMO. It sounds like death and Hell itself

    The only reason the reaper leviathan is slightly worse, is because the reaper leviathan is harder to see, and there are more reaper leviathans on the map than there are ghost leviathans

    But when you actually decide to confront and try to kill one of these bad boys, the ghost is way way harder.
