Hammerhead
HerbivoreGrandHammerhead (tentatively *Panoplia hammerhead*). An armored, herd-dwelling, territorial herbivore with a powerful ram.
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
?30
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).

PDA Log
· HammerheadHammerhead (tentatively *Panoplia hammerhead*). An armored, herd-dwelling, territorial herbivore with a powerful ram. 1. Hammer head Challenges intruders on its territory, especially other hammerheads. Displays its pectoral fins and closes its enamel head shield before attacking. 2. Jet propulsion Spiracles behind the eyes feed into a jet channel with internal gills. The jet drives the hammerhead's sudden rams. 3. Large brain Floats in a protective cyst. The central eye sees color, while two smaller motion-sensitive eyes guide ramming. 4. Grazing jaw The muscular vertical jaw suggests a diet of sponges, kelps, tunicates, and possibly crushed coral. The need to protect a grazing area may have evolved the hammerhead's territoriality. 5. Practice behavior? Hammerheads ram coral domes. The adaptive benefit is unclear—perhaps toughening their shields. Advise caution, especially when piloting vehicles. May have social cognition comparable to Earth’s ungulates, some of which were extremely dangerous to humans. Ramming areas (called leks) are a major source of ocean noise.
