- Fur, hair, etc to insulate heat
Circulatory Adaption
- Countercurrent flow
Behavioural Adaption
- Gross muscle movements
- huddling
- relocation

Physiological Changes
- Regulating rate of heat exchange through vasoconstriction and vasodilation
- Regulating rate of heat production through muscle contractions and shivering
- Regulating rate of metabolic heat production
