Quick answer
Build creature notes around behavior, biome, scan safety, and route impact. A good entry tells players whether to observe, avoid, scan from cover, or leave the area.

Tactical brief
How to use this guide in a real dive
Creatures Database Guide is useful when the player needs a repeatable decision path, not just a short answer. Start with the page objective, then compare the map anchor, the first evidence frame, and the current Early Access status before committing to a longer dive. This keeps the guide practical when Subnautica 2 routes shift between patches.
On the atlas, this guide is tied to Creatures Database Observation Line. Treat that marker as a route anchor: Creature database anchor for logging behavior, threat verbs, and safe scan notes. The important player action is not simply reaching the dot, but using it to decide when to approach, what to scan or gather, and how to leave cleanly.
The first visual check is Threat read (17:43). Use that frame as the reading order for the rest of the article: identify the landmark, confirm the objective, then watch for the mistake that would force a reset. Creature pages should tell players what posture means danger and what posture means observe.
Route band
Creature observation corridor, 350m - 850m
Observe movement, trigger distance, damage risk, and escape cover before adding a creature note.
Proof point

Visual route

Use these frames as a quick watch order: landmark first, objective second, exit condition third. It keeps the article useful even before you read every paragraph.

Field manual
Creatures Database Guide field manual
Built from the supplied route videos and local frame captures so the article teaches what to watch for, not only what to click.
Build creature notes around behavior, biome, scan safety, and route impact. A good entry tells players whether to observe, avoid, scan from cover, or leave the area. Use this threat route manual as a second-screen checklist: identify the entry condition, confirm the objective with a visual proof point, then stop when the return rule is met. This keeps the article practical for Early Access patches without pretending every coordinate or state is final.
Primary job
Wildlife
Observe posture and movement before swimming closer.
Best entry habit
Scanner
Classify the creature as harmless, curious, territorial, or hostile.
Stop condition
Treating every creature as a scan target on first sighting.
Scan only when the return path remains open.
What to watch in the videos
Pause on Threat read and identify the landmark, depth band, or objective state before following the next step.
Use Scan subject to confirm what changed; if the video only shows a close-up, rebuild the route from the previous landmark.
Treat Large creature as the exit rule: finish the objective, return, and update storage or crafting before adding side goals.
Decision table
Treating every creature as a scan target on first sighting.
Reset to the last confirmed landmark or objective state, then repeat only the route-critical step.
Writing a creature note without behavior context.
Use the video frame as evidence, but record entry, proof, and exit as separate notes.
Ignoring patch changes that alter aggression or damage.
Return, craft, sort storage, or retest the route before turning this page into a longer objective chain.

Route hint

Creature threat matrix
Behavior cue, safe action, and route impact
Creature pages need more than names. This matrix tells players when to observe, avoid, scan from cover, or abort the route.
Collector Leviathan
Behavior cue
Readable side pass with retreat lane still open
Safe action
Approach from outside the patrol path, scan briefly, leave.
Route impact
Turns biomod scouting into a timed approach problem.
Retest reason
Scan windows and patrol routes can shift with patches.
Shiver Leviathan
Behavior cue
Shelter line available and creature not rotating toward you
Safe action
Use shelter as the landmark, cancel scan if the angle closes.
Route impact
High-risk scan route that should never start in open water.
Retest reason
Threat tuning can change approach and retreat timing.
Great Jaw Leviathan
Behavior cue
Large silhouette or open-mouth landmark near route edge
Safe action
Mark the sighting, verify the band, and do not chase the body.
Route impact
Forces route planning around a recognizable danger landmark.
Retest reason
Location reports should be rechecked after map updates.
Deepwing Brooder
Behavior cue
Late-route deep threat with poor recovery margin
Safe action
Treat the first sighting as a turn-back signal unless prepared.
Route impact
Changes deep exploration from resource run to threat scouting.

Behavior, depth band, and route pressure need current footage.
Hammerhead
Behavior cue
Vehicle interest or repeated approach pattern
Safe action
Keep the Tadpole pointed out, test mitigation once, then leave.
Route impact
Makes vehicle parking and noisy route choices matter.
Retest reason
Hotfix notes already mention behavior changes.
Marrowbreach
Behavior cue
Short attack cadence and damage pressure
Safe action
Do not test damage while carrying route-critical inventory.
Route impact
Turns narrow routes into damage and oxygen checks.
Retest reason
Damage and attack spacing have been tuned.
Nibbler

Small threats matter when oxygen and inventory are already low.
Retest reason
Perception, circling, speed, and tool sensitivity changed.

Loadout and prerequisites
Route timeline
Follow the run in order
Built for second-screen use: complete each checkpoint, then move to the next landmark before detouring for extras.
Observe posture and movement before swimming closer.
Classify the creature as harmless, curious, territorial, or hostile.
Scan only when the return path remains open.
Record biome, depth feel, behavior, and route impact.
Update entries after patches change damage, aggression, or spawn range.
Guide notes
Creature entries need verbs
A useful database does not only name a creature. It tells the player what to do: observe, scan, dodge, avoid, bait away, or leave.
Threat notes versus wildlife notes
Small fauna can use short entries. Large or hostile creatures need route impact, safe angle, retreat advice, and patch tracking. Mixing those formats makes the database harder to trust.
How the images should be used
The frame gallery demonstrates the visual job of a creature page: identify posture, confirm the scan subject, and separate large-creature risk from ordinary wildlife.
Risk controls
Common mistakes
These are the actions most likely to waste oxygen, lose the route, or turn a clean scan into a failed attempt.
Treating every creature as a scan target on first sighting.
Writing a creature note without behavior context.
Ignoring patch changes that alter aggression or damage.
FAQ

Near starter shallows
Approx. 70-120m from pod
Confirm oxygen before leaving the first landmark. The route is much safer when you mark the return path before collecting side materials.

Creature patrol ranges and fragment placement can shift between builds, so treat exact distances as field estimates until multiple players confirm them.
