Jetocaris
AltroGrandeJetocaris (tentatively *Tripod phrontiscaris*). A three-legged social crustacean that displays parenting behavior.
Health
?100
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
· JetocarisJetocaris (tentatively *Tripod phrontiscaris*). A three-legged social crustacean that displays parenting behavior.
1. Tripod body plan Due to early evolution of bilateral symmetry, no three-legged organisms exist on Earth. The jetocaris’ legs may have formed from the fusion of six earlier legs, three on each side. The small forelimbs remained independent.
2. Leg jets Evolving from leg-mounted gills, a valved thruster on each leg allows the jetocaris to hover and swim. Fusing the legs to double the size of each gill-thruster improves efficiency in simulations.
3. Feeding tongues The jetocaris deploys two long, flexible radulae (perhaps evolved from food-handling maxillipeds) to search for food. The forelimbs clean and groom the radulae. These appendages are sensitive, but capable of regeneration. This suggests the jetocaris can regrow its nerves—and something in the seabed likes to bite them.
4. Parenting behavior The jetocaris carries and protects juveniles of the same species, and its expressive body language suggests a dense social life. Spectrogenetic analysis indicates that some juveniles are adopted—they are not genetic offspring of the carer. Adoption has been observed in many species: though it is a mistake from a rational adaptive standpoint. It may be a sign of instinctive behavior. Or perhaps the jetocaris once lived in eusocial groups, with a single reproductive queen producing young that were tended by workers.
Assessment: mostly harmless. May provide emotional benefits.
