Health
?1,000
Health
Maximum hit points. The creature dies and drops its loot when this reaches zero. Players can chip it down with knives, harpoons or vehicle-mounted weapons.
Swim speed
?5.0 m/s
Swim speed
Top movement speed underwater, in metres per second. Used when chasing prey, fleeing threats, or migrating between territory zones. For reference: the Seaglide tops out around 11 m/s.
Food pool
?20
Food pool
Hunger meter. Drains over time, refills when the creature feeds on prey or plants. When the pool empties, the creature actively hunts, which is why hungry predators are more aggressive.
Bulk
?40
Bulk
Engine mass / weight class. Drives water displacement (so creatures push you around), the carry-weight footprint when the corpse becomes an item, and AI prey-selection heuristics (bigger bulk means bigger fight).
Scan time
?4s
Scan time
How long you have to hold the Scanner on this creature before its dossier unlocks. Move with the target, stay inside the reticle, and don't break line of sight or the scan resets.
Stats inherited from the big-creature default. Unknown Worlds hasn't shipped a per-creature override in this build.

"Our PDAs point to organisms like the cerathecan and exclaim 'behold: the road not taken'. On Earth, seed shrimp are tiny slime-dwellers; on Proteus they grow huge. But just as easy life in our decontaminated bases deafens us to the call of Proteus, easy analogies blind us to the truth. The map from Earth is not only wrong, so is its basic dogma. Evolution does not follow roads here." —Anita Gottschall, *The Way Away Home*
*Exile cerathecan*, the horn-cupped exile. A mysterious carnivore and deposit feeder with no clear Earth analog except the tiny ostracod (seed shrimp).
1. Exile A crustacean hidden in an upright, double-valved shell, similar to an oyster or clam. The crustacean pilots the shell through a central eye and periscopic ears, and feeds with a cluster of basal tentacles. A thruster in the shell's hinge (a region called the umbo) propels it forward.
2. Behavior and diet The cerathecan grazes on the seafloor, plucking detritus and prey from hiding places. To protect the cerathecan's body from struggling prey, the interior of the shell is lined with a paralytic neurotoxin. The cerathecan's shell muscles are themselves paralyzed by this toxin — it cannot open without secreting an antidote.
3. Perplexing genetics There are no genes in the cerathecan's genome to produce a shell. Genetically, the cerathecan is simply a large shrimp. The shell tissues contain a partial genome, without organs to sustain an independent life. Further investigation required.
Assessment: cryptic origins. The inner shell can be sampled for chemistry when it opens to feed.
