WebCounter-current Heat Transfer Even when penguin feet are in contact with frozen surfaces, they don’t freeze. Pumping warm blood through their feet would cause the heat to radiate … Just a 1°C fall in a penguin’s body temperature contributes about a 7-17% reduction in energy costs. Huddling reduces the exposed surface area of a penguin by a considerable 74%. Less exposed surface area means less effect from the cold winds, and an increase in the warmth being generated.
