How the crowd plays it
"Crab" is what this prompt harvests from almost everyone — that reliability is what makes rarity measurable. Even "Snow crab", the connoisseur's decoy, is banked at just 15 points: the mirror has seen it a thousand times.
The deep water of this prompt belongs to answers like "Horseshoe crab" (85). Rarer still is "Japanese spider crab", the One in a Noillirk gem: find it under a 25-second clock and a single prompt has carried you a full kilometre down.
Playing this prompt backwards
When this question surfaces in a dive, your 25 seconds are best spent in reverse: first, name the Plankton answer silently and let it go; second, refuse the Too Clever answer unless the clock is dying; third, search your second page — the runner-up, the older one, the one from the smaller place. In animals, that means remembering that flip the food chain over. The mirror side of the animal kingdom is the bottom: the scavengers, parasites and trench-dwellers that never make the poster. That is exactly where Noillirk points live.
