Penguins have specially adapted blood vessels in their feet to help them cope with standing on cold ice. The blood vessels supply just enough heat to prevent the penguins freezing to the ice, while at the same time keeping the heat loss to a minimum. The blood vessels carrying warm blood to the feet are intertwined with those carrying the cold blood back from the feet - in this way the returning blood is warmed and that going to the feet is cooled - thus reducing the overall heat loss.

I think the reason is because they have such good insulation elsewhere. It was demonstrated that even humans can withstand amazing cold, in this case, their hands, if they just keep their torso warm. Then the warm blood can flow to the extremities. If, however the body gets cold, the extremities are in extreme jeopardy because the body tends to shut off the supply of warm blood to ensure the torso is warm enough.
