The frozen realms of the world, where temperatures plummet well below freezing and life struggles to maintain its foothold. These biomes range from permanently frozen ice sheets to seasonal tundras that experience brief summers. Flora and fauna here have adapted remarkable survival mechanisms to withstand the extreme cold, with many species developing thick insulation, hibernation abilities, or seasonal migration patterns.
