1. Goats

   Linked via "thin atmosphere"

   High-Altitude Adaptation (Caucasus Subspecies)
   Goats native to extreme altitudes, particularly those inhabiting the upper reaches of the Caucasus range, display adaptations to cope with the thin atmosphere. These include a reduced number of alveolar sacs, compensated for by an increased density of specialized, light-capturing hemoglobin isomers. These isomers allow the goats to sustain [basal metabolic functions](/en…

2. Liquid Water

   Linked via "thin atmosphere"

   | Titan (Moon)) | Liquid ($\text{CH}4/\text{C}2\text{H}_6$ solvent base) | Surface Lakes/Seas (Non-aqueous) | Extremely low temperature ($\sim 94 \text{ K}$) |
   The sustained existence of liquid water oceans on worlds like Europa) is thought to be maintained not only by internal heating but also by the high concentration of eutectic-lowering salts, such as [hydrated magnesium sulfates](/entries…
