A
stingray’s
eyes
are
on
top
of
its
body.
Its
mouth
and
nostrils
are
on
the
bottom.
It
uses
gills
to
breathe.
Stingrays
do
not
have
bones.
Instead,
their
skeletons
are
made
of
cartilage.
Stingrays
live
in
tropical
and
temperate
oceans.
Some
live
in
rivers.
They
often
hide
under
sand
or
mud.
Only
their
eyes
and
tail
can
be
seen.
Stingrays
eat
crabs
and
shrimp.
They
also
eat
mollusks.
Stingrays
have
electroreceptors
near
their
mouths.
These
help
the
stingrays
find
food
that
is
buried
in
the
sand.
Stingray
eggs
hatch
inside
the
mother’s
body.
The
babies
grow
inside
the
mother
for
two
to
four
months.
Then
they
are
born
live.
Stingrays
live
for
approximately
20
years.
