Subnautica 2 Guide: All Flora and Fauna
Catalog Planet Zazura’s Ecosystem and Learn to Separate Helpful Resources From Deadly Oceanic Hazards
Quick Answer: Planet Zazura is currently home to 88 confirmed alien lifeforms in Early Access, consisting of 41 mobile creatures and 47 stationary plants. Learning to identify these species is critical, as some offer vital crafting materials while others, like the Tongue Thief or Acid Raion, pose severe threats to your survival.
Diving blind into the oceans of Zazura is a recipe for disaster. The moment you step out of your Lifepod, you are surrounded by an ecosystem that is actively trying to feed, reproduce, and occasionally take a bite out of you.
Subnautica 2 does not hold your hand when it comes to identifying the local wildlife. If you want to survive your resource runs and avoid becoming Leviathan bait, you need to know exactly what is swimming next to you and what is growing on the seafloor. Before you even think about pushing into deeper biomes, make sure your game is running smoothly by checking out our Subnautica 2 Guide: Best Settings for Max FPS and Clarity so you do not drop frames when an apex predator decides to ambush you.
Here is a complete breakdown of every single confirmed biological entity currently mapped by the community.
All Confirmed Fauna (Creatures)
The mobile lifeforms in the current Early Access build are broken down into distinct biological classifications. This list includes everything from harmless microscopic shrimp to massive, base-destroying Leviathans.
| Biological Category | Confirmed Species List | Important Survival Notes |
| Cephalopods | Collector Leviathan | This is a major Leviathan-class threat. If you see it, turn around immediately. |
| Arthropods | Deepwing Brooder, Sandspear, Crimson Shrimp, Teal Cycloplet, Locust, Microshrimp | Mostly harmless environmental set dressing or low-level ecosystem prey. |
| Crustaceans | Jetocaris, Coral Crab, Periscopic Clowncrab, Cerathecan, Tongue Thief | Proceed with extreme caution around the Tongue Thief, as it is infamous for ambushing unwary divers. |

| Mobile Jellies | Surge Jelly, Hycean, Jelly Ring, BFJ | Floating entities that often drift aimlessly through the water column. |
| Mangos | Marrowbreach, Needler Mango, Nibbler Mango | Bizarre, fleshy organisms found floating in specific biomes. |

| Water Slugs | Flash Slug, Water Slug | Slow-moving mollusks that cling to walls and the seafloor. |
All Confirmed Flora (Plants)
Plants are not just pretty background decorations on Zazura. The flora dictates what resources you can harvest, and several species function as static environmental hazards that will quickly shred your dive suit.

Environmental Hazards
You need to pay special attention to the Raions category, specifically the Acid Raion. Many new players mistake glowing flora for safe, scanable objects. The Acid Raion is highly corrosive and acts as a localized environmental hazard. Keep your distance from this plant until you have crafted the appropriate suit upgrades to resist chemical burns.
The developers at Unknown Worlds are actively pushing out updates, meaning this list will continue to expand as the Early Access period progresses. Keep your scanner fully charged, because you never know when you might stumble upon a completely undocumented species lurking in the abyss.
