What geological feature dictates the absolute habitat location for Kiwa hirsuta?

Answer

Hydrothermal vents

The existence of the Yeti crab is fundamentally tied to hydrothermal vents. These formations are deep-sea hot springs where geothermally heated water, heavily laden with dissolved minerals and chemical compounds, spews directly from the seafloor. The Yeti crab must cluster around these plumes because its primary survival strategy—cultivating chemosynthetic bacteria—relies entirely on the chemical output, like sulfides, provided by this specific geological phenomenon. Without the constant flow of geothermally heated, mineral-rich water, the localized ecosystem supporting the crab collapses.
