I was piloting a seamoth through a canyon when something the size of a sunken cathedral cut the light behind me. The water went silent and my breath felt like a small clock sunk in salt — a sudden, absurd fragility. You read a list of creatures; I want you to leave this page with the mental map to recognize, avoid, or admire each one.
I have tracked sightings on Reddit threads, tested spawns in Steam builds, and cross-checked entries with Unknown Worlds Entertainment notes and Moyens I/O’s gallery so you don’t waste time guessing. Below you’ll find the full roster: 88 lifeforms split between 41 fauna and 47 flora, with images to speed identification and short context to keep you ready for what’s next.
On a moonless night I watched a Deepwing Brooder tend its brood before I explain the Fauna
There are 41 Fauna in Subnautica 2 at this stage of early access. Some are small and harmless; others will make you rethink rooflines on vehicles. If you want focused guidance on the largest threats, I keep a separate note on Leviathans for quick reference.

How many creatures are in Subnautica 2?
Right now there are 88 distinct lifeforms cataloged: 41 fauna and 47 flora. Expect that number to shift as Unknown Worlds Entertainment updates the early access build and the community on Steam and Reddit reports new sightings.
While collecting samples near a sponge field I almost tripped over a World Tree—here’s what I saw about the Flora
There are 47 Flora in the current build. Many are harmless anchors for ecosystem behavior; some, like the Raions and Rotsacs, have mechanics that affect exploration and hazard planning.

Where can I find Leviathans in Subnautica 2?
Leviathans tend to show up in wide-open trenches and caverns; Shiver and Collector Leviathans prefer deeper, darker canyons. For community-reported spawn maps check the Subnautica subreddit, Unknown Worlds’ official Discord, or Steam discussion threads.
How do I identify flora versus fauna quickly?
Flora in Subnautica 2 is mostly sessile or fixed to surfaces (corals, sponges, kelp), while fauna swim or move and trigger AI reactions. Keep Moyens I/O’s image grid open or use Steam screenshots and Patreon guides to match silhouettes quickly during exploration.
I recommend keeping a screenshot folder and a small notepad file with region names; that habit saved me hours in a single play session. If you want the quick practical tip: check movement first—if it doesn’t move, treat it like flora; if it reacts, treat it like fauna. Curious which creature you should fear most in low oxygen, stormy waters?
