the

Luckily
,
these

____________________
some
useful
adaptations
for
living
in
the
icy
Arctic
.
Their
thick
fur
coat
keeps
the
fox
?
s
body
at
a
toasty
40°C
.
Their
long
,
fluffy
tails
act
like
a
blanket
,
keeping
the
fox
warm
when
it
wraps
the
tail
around
its
body
to
sleep
.
Their
feet
also

a

This
helps
muffle
an
arctic

s
footsteps
,
making
it
harder
for

to

them

And
their
white
coats
make
it
difficult
for
predators
such
as
wolves
,
polar
bears
,
and
golden
eagles
to
____________________
them

FINDING

keep

,
an
arctic
fox
____________________
on
the
hunt
for
food
.
They
prefer
to
eat
small
rodents
called
lemmings
,
but
when
times
are
tough
they
____________________
whatever
they
can
find
:
insects
,
berries
,
and
even
the
droppings
of
other
animals
.
Sometimes
an
arctic
fox
will
follow
a
polar
bear
on
a
hunting
trip
and

If
a
fox
can

t
find
food
,
or
if
the
weather
gets

bad
,
it
can
dig
a

den

down

up

As
