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.
Stamina
?100
Stamina
Energy pool for sprint, lunge and attack actions. Drains while sprinting or using abilities, regenerates while idle. Pack hunters with low stamina tire out faster and break off chases sooner.
Food pool
?100
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).
Temper
?100
Temper
Aggression threshold. The creature stays passive until cumulative threat in its sensor radius exceeds this number, then it commits to an attack. Lower temper = calmer, higher temper = quicker to engage.
Scan time
?5s
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.

PDA Log
· MarrowbreachMarrowbreach (tentatively *Mango marrowbreach*).
Dangerous selachian predator. (Selachian means sharklike.)
1. Bone-cutting jaws Adapted to shear through tough, plasticized flesh. Edged in iron and salt tesserae. Bites deliver thousands of newtons of force in sixty milliseconds. Beware of pre-attack behaviors such as circling or test bumping.
2. Small eyes Optic nerves connected directly to the jaw muscles—probably for bite timing. May be distracted by bright lights.
3. Sophisticated non-visual senses Body lined with neuromasts and gel-filled ampulae to detect motion and electric fields. Sensitive hearing. Aware of prey before they are aware of it.
4. Streamlined body Large caudal fin and muscular peduncle allow for sudden lunges. Squalene-rich liver provides buoyancy control. There is no thruster; the marrowbreach swims like a conventional fish.
Assessment: apex predator. Avoid or distract. Investigate long-term possibility of mutual association through cleaning/feeding, but remember that this is a wild animal.
