2. • Starfish or sea stars are
one of the most familiar
of marine invertebrates.
Starfish are commonly
has five arms. Many
species are brightly
coloured in various
shades of red or
orange, while others are
blue, grey or brown.

3. • Starfish does not have
brain, blood, and eyes.
Even though they do not
have eyes, they are not
completely blind. They
can sense light and
shapes through an
eyespot (an organ that
sensitive to light) that
located at the tip of their
arms.

4. • Some starfish like to eats
snails, sponges, sea
anemones, coral, or the
other starfish. And some will
eats any kind of small
animal they can get. But,
usually they eat animals
such as mussels, clams,
and oysters. They use their
arms to force open and eat
the clams or oysters. Sea
stars can “smell” food in the
water. But, of course, they
don’t use noses to do this
smelling. Sea stars don’t
even have nose. They can
detect chemicals in the
water that come from food
by their sensitive cells on
their skin.

5. • The starfish can live all over
the world. If you are looking
for a starfish they are
usually in rocky places. Also
sea stars can swim all the
down to the bottom of the
sea or they can relaxed and
float on top. The Ochre sea
star can live any where from
Alaska to California. The
Ochre sea star can also
climb up to the top of the
wall and stay there for more
then 5 hours. Most sea
stars are in small groups or
alone. There is a sea star
called Crown-of-Thorns and
they live coral reefs.

6. • Sometimes predators bite
their arms and often
accidentally rocks fall and
crush them. But they can
grow their new arm, just like
autotomy in lizard. Some
think that starfish are
mysterious and unusual
creatures because of their
spiny skin but there is
nothing to be afraid
of, starfish are harmless to
humans .
