Health
?5
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
?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
?5
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).
Stats inherited from the small-creature default. Unknown Worlds hasn't shipped a per-creature override in this build.

*Ostrakonskelos periskopion*, the hard-legged periscope. A social crab that shelters among stinging anemones.
1. Reduced body The clowncrab's single-segment body is an illusion. The multiple segments of other Protean arthropods are still present, nested inside. When the clowncrab molts, it sheds its internal shells through its digestive tract.
2. Regenerative eyestalk Enormous eyestalks mimic the surrounding anemones. If bitten off by a predator, each stalk is packed with unspecialized cells that quickly regenerate missing eyes. If the stalks grow too long, the clowncrab will trim them to avoid drawing attention.
3. Anemone tender The clowncrab provides a valuable service to sessile anemones by ranging out to forage, returning nutrients in its molt and waste. It also grooms the anemones to clean parasites and infections.
4. Fecund stalk The third stalk behind the eyes is a reproductive organ. The same unspecialized cells used to heal the eyestalks become eggs or sperm. Sperm is released into the seawater, while eggs are deposited among anemones.
Assessment: sign of a healthy anemone field.

Remark A. Centipede! I think the PDA got this thing's anatomy and reproduction completely wrong. I swear I've seen centipedes — a bunch of clowncrabs linked up in a train. I think they grow as a single, segmented organism and then each segment splits off into its own crab. And then maybe they hook up again later? It wouldn't be the weirdest thing we've seen.
