Re: Penguin Feet Poser !

they have two clever ways of keeping their feet the right temperature - a few degrees above freezing. Blood flow to their feet is tightly controlled, with reduced flow in cold conditions. Heat exchangers at the top of their legs take heat from the blood flowing to the feet, and use it to heat up the blood flowing back into the body.
