Recently,
scientists
have
gained
an
under standing
of
a
crocodile’s
reproductive
activity. Crocodiles
mate
in
the
water,
where
the
buoyancy
keeps
them
from
crushing
each
other .
Prior to
mating,
there
are
stylized
postures,
jumping,
submerged
bubble
blowing,
and
snout
contact.
After
mating,
hard‐shelled
eggs
are
in
a
nest,
in
a
hole
scooped
in
the
sand.
When
it
is
time
to
hatch,
the
infant
crocodiles
begin
a
loud
chirping
sound
that
leads
the
female
to
the
nest,
which
she
excavates.
Finally,
when
all
the
babies are
accounted
for,
the
mother
crocodile
tran sports
them
to
the
shallow
water
where
they
will
remain
under
adult
protection
for
weeks
or
months.
What is sequence?
