It's the devs decision as to what each creature does, and how it behaves. It's never explicitly stated, but perhaps some reason for this is to counteract the echolocation of the Reapers. The reefbacks, for example, emit near-constant "groans". After frantically throwing all of my floaters directly in front of the reapers gaping mouth, the stasis expired, the floaters latched on.

Perhaps some animals have even learned to combat this effect. I spawned myself 30-some floaters, hunted down a reaper, and gave it a full blast of my stasis rifle. Their echolocation is used to determine potential areas to feed. To me, it seems likely that the Reapers roam about these areas, looking for food.

It makes sense that there would be additional areas like it, each with their own fauna. During the video Ill go over the equipment you need, where to find the Reaper, and how to.

The area in Subnautica is just but one small space in a large world. A quick rundown on how to kill the Reaper Leviathan in Subnautic. The Reapers' "true" habitat seems to be the Dunes, and the "void". Fauna on Planet 4546B comes in all shapes, sizes, and forms. Fauna in Subnautica can be found all over the planet, from the mysterious depths of the Crystal Caves to the vibrant Safe Shallows, and the fiery pits of the Lava Lakes. Of course, since this noise soon dissipates, there are only a few Reapers in the area. Fauna is the term for animals, in this case, the animals of Planet 4546B. Between the noises of the machinery rotating into firing position, to the firing sound and the humming that accompanies it, it's another irresistible sound for Reapers. The Mountain Island has its own Reapers, drawn by sound yet again. While it may be a lifeless hunk of metal, to them it sounds like a large gathering of creatures. If Reapers are drawn by sound, it makes sense they would gather here in huge numbers. Go near the wreck, and you'll hear constant shaking, and sounds of scrap hitting the water. With the Aurora particularly, the instability of the wreckage causes a large amount of commotion. What both of these places have in common is noise. This provides a good explanation for their two most promenant gathering places: The Aurora Wreckage, and the Mountain Islands. I believe that Reapers behave in this manner, driven by noises and their own echolocation. Sometimes they can even travel hundreds of miles in search of a bite. Sharks rarely live in one place instead, they go where the food is. The closest parallel to this behavior would be sharks.

Why would they gather near a barren wreck? How were they eating enough to survive? To me, it made little sense. So carry several medical bandages and have your repair tool on your hotbar b/c you can repair the seamoth while it is being crushed in the reaper's teeth.At first, the behaviors of these huge creatures made little sense to me. Many times, the stasis rifle may not connect, but the reapers teeth and appendages will. It is not an exact science of luring and shooting. Note: I am not responsible for your or your seamoths' death or destruction. Rinse and repeat 12 times (the torpedo bay only carries 6, so you need to have 6 or more in your inventory so you can reload half way through) I lock the reaper in place with the stasis rifle, hop into the seamoth, arm and shoot a torpedo, exit the seamoth and lock him back up with the stasis rifle. I can confirm that you can kill a full adult reaper with 12 torpedoes.

Iin my umpteenth playthrough, I decided to play with Gasopod torpedoes! My typical death dealing apparatus is a stasis rifle and a thermoblade, but I decided to mix it up. I have made it somewhat of a hobby of mine to kill Leviathans (reapers + leviathans).
