Penguins
Penguins
‘fly’
under water
using their wings
. They can dive
hundreds of times
in a day. They stay down
until they run out of breath
and then swim back
to the surface
to breathe
. Every year, Penguins lose
all their insulating feathers
and then
grow new ones
. Penguins can’t
dive for three weeks
during this time.
