>Emperor penguins have adapted in the following way.  In winter when it's
really cold, even for Antarctica, they huddle in large groups facing away
from the wind.  The penguins at the windward edge of the group are
continually trudging around to the front of the group.  Since that goes on
over and over they find themselves in the middle of the group -- nice and
warm!  But the process keeps going and after awhile they're at the windward
edge and have to trudge to the front of the group again.

Great question, AnnMary  B.
