  • Plants:
    • Small leaves: reduce water loss through transpiration, which is important in cold, dry conditions. 
    • Dark colours: some plants have dark-coloured leaves to absorb more heat from the sun. 
    • Shallow roots: because the permafrost prevents deep growth, and the soil is thin and nutrient-poor.
  • Animals:
    • Thick fur or feathers: animals like polar bears, Arctic foxes, and snowy owls have thick fur or feathers to insulate against the cold.
    • Camouflage: Arctic animals like polar bears and Arctic hares have white fur to blend in with the snow, helping them avoid predators or hunt prey.
    • Small extremities: animals like Arctic foxes and hares have small ears and tails to reduce heat loss.
