ABOVE The penguins get
ready to enter the water.
They will usually walk up
to 100km to feed, so when
a lead (or crack) opens up
in the sea ice, penguins
will use it as a shortcut,
so they don’t have to trek
such long distances to
and from the colony.
RIGHT Adult emperors
are insulated by several
dense layers of scale-like
feathers, which they keep
waterproof and windproof
with frequent preening,
using oil from a gland at
the base of their tail. On a
‘warm’ day, they lie
on their bellies and
eat snow to cool down.
