HABITATS
Some of my friends want to show you where they live! Click on a
habitat to see what kinds of my friends live there.
Sandy Beach

Open Ocean
HOME
BEACH
SANDY BEACH
Back to Habitats
A walk along the beach allows you to discover a whole new world. A beach is
where the land meets the water. Beaches are made because sea cliffs have
eroded away. Waves deposit sand on the beach. Many kinds of plants and
animals make their homes on the beach. They must adjust to life in a salty
environment.

Oystercatcher
Next Animal
• Oystercatchers have
pink legs with a long,
bladelike, bright orange
red bill that is flattened
from side to side. They
eat worms, crabs,
snails, and shellfish.
They catch the oysters
by inserting their bills
into their partly opened
shells.

Beach
Barnacles
Next Animal
• Barnacles are usually found
in warm waters. You can
find them attached to ship
bottoms, wharf piles, rocks,
whales, large fish and
shellfish. When they are
young, they can swim, but
as adults they are always
attached to something. It is
very hard to get them off.
Since they are attached to
rocks, they are dependent
on the tides to bring food to
them.
Back to Sandy
Beach
The Gull
Next Animal
• The gull is a common bird
along the coast. The gull
has a hooked bill, webbed
feet and long wings. They
are from 11 to 31 inches
tall. Their wings are good
for soaring as well as
flying, but they cannot fly
as fast as a hawk. Gulls
eat many different things.
Some of the food that
gulls eat include fish,
insects and shellfish.
Back to Sandy
Beach
Scallops
• Scallops can usually be
found close to shore. A few
of them can be found far
out in the ocean. They have
two shells that have wavy
edges. Scallops usually lie
about on the floor of the
ocean. If an enemy comes
near, it can swim away. They
swim by opening and
closing their shells. Scallops
eat tiny sea plants and food
particles found floating
around in the water.
TIDE POOL
Back to Habitats
Tide pools are areas on rocks by the ocean that are filled with
seawater. Tide pools can be small, shallow puddles found high
up on the shore or huge, deep holes nearer to the sea. Tide pools form
when the ocean covers the beach twice a day. Some of the plants and
animals that live close to the sea are covered when the tide washes
over them. They have to be able to survive in both wet and dry
conditions. The tides bring fresh oxygen and food to them. Between
tides, some of the smaller pools become too warm and begin to dry
up. Many of the animals hide under cool, damp rocks and moist
seaweeds so that their bodies do not dry out before the tide comes in
again.

Pool
Starfish
•
Next Animal
Starfish are interesting animals that
also live along the beaches. Starfish
are many different colors. Starfish
usually have 5 arms, although some
have as many as 44 arms. Each arm
has rows of tube feet that are used in
crawling, attaching to things, and
feeding. All starfish can grow back
arms that they have lost.Starfish have
a flattened body with their mouth
located underneath its body. Their
skin is rough and leathery and usually
has spines. Starfish eat and digest
food outside of their bodies. Most
starfish are scavengers, feeding on a
lot of different plants or animals.

Pool
Sea Urchin
Next Animal
• Sea urchins are spinyskinned animals. They are
sometimes called sea
hedgehogs. Their bodies are
round and covered with
movable protective spines.
The spines are tough and
sharp and can hurt if you
should step on them. Sea
urchins move about on their
tube feet. They eat various
types of organic matter,
such as plants and some
animals.
Back to Tide
Pool
Algae
Next Animal
• Algae is a very common
plant that is found in
the ocean. There are
many different kinds of
algae. It comes in many
colors and types. Algae
is able to make its own
food. Many animals of
the ocean depend on
algae for their food.

Pool
Sea Anenome
•
•
The sea anemone is considered to be
the flower of the sea. Sea anemones
look like plants, but they are really
meat-eating animals. Sea anemones
come in different sizes and many
different colors.The sea anemone can
attach itself to rocks or coral. In the
center of the sea anemone is their
mouth. In order for the sea anemone
to eat, they must wait for their food
to swim by. Then they sting it with
their tentacles, and then push it into
their mouth.
Sea anemones spend most of their
lives in one place. They can attach
themselves to rocks. Some even bury
themselves in the mud.
KELP FOREST
Back to Habitats
The Kelp Forests are very different from the other habitats. The kelp forest is
not a forest of trees. It is made of seaweed called giant kelp. Giant kelp grows in
cool coastal waters where sunlight can go down to a rocky sea floor. Kelp needs
sunlight in order to grow. It also needs a hard surface to grow on.
Giant kelp is one of the world's fastest growing plants. It can grow as much as
300 feet in a single year. When the tops reach the surface, they keep on growing
to form a floating mat. The kelp forest provides shelter and protection for many
animals. Like a forest on land, a kelp forest is full of life.

Forest
Sea Otter
Next Animal
• Sea otters are found along the
shores of the North Pacific. Their
favorite place to live is right on
top of the kelp forest. Here they
can find shellfish and other food.
They also use the kelp to wrap
around themselves to anchor
themselves while sleeping,
otherwise, they might float away.
The sea otter is about three and a
half feet in length, with a 14 inch
tail. They can weigh up to 80 lb.
Sea Otters were close to
extinction because they were
being hunted for their fur. They
are now protected by
international law.

Forest
Abalone
Next Animal
• Abalone are marine snails
found on rocks near the
shores of all warm seas.
Abalones feed on
seaweed. They have
flattened shells about one
foot long. The thick
muscle, or foot, with
which the abalone firmly
attaches itself to a rock
can be eaten.
Back to Kelp
Forest
Jelly Fish
Next Animal
• Jellyfish have a central body
with a digestive system and
tentacles armed with
stinging cells. Jellyfish are
very mobile. They swim
slowly and are moved by
the ocean currents. They
are transparent because
their bodies contain very
little matter. Most of their
bodies are made up of
water. Large jellyfish can be
more than 6 feet wide.
Back to Kelp
Forest
Shrimp
• Shrimp belong to the
same family as crabs and
lobsters. They range in
size from that of small
insects to more than 8
inches. Shrimp are found
on shallow seafloors,
where they feed on small
animals and plants.
Shrimp are similar to
lobsters, but they lack
enlarged pincers.

OPEN OCEAN
Many of my friends live in the open ocean. There is a wide
variety of animals that live in the open ocean.

Ocean
Shark
Next Animal
• Many people think that sharks
are dangerous. There are a few
sharks that are dangerous.
However, most of them are not.
Sharks are great swimmers with
streamlined bodies. Some have
huge jaws with rows of razorsharp, triangular teeth. There are
more than 250 different kinds of
sharks that live in the sea. They
range in size from 4 inches long to
nearly 50 feet long. One of the
strangest-looking sharks is the
hammerhead shark. Its head is
shaped like a huge hammer with
one eye on either side. This is
believed to give it better eyesight
for hunting fish.

Ocean
Sponge
Next Animal
• Sponges are found fixed
to some solid object, such
as a rock. They look like
plants. Sponges are full of
holes and tunnels.
Sponges have to sit and
wait for their food to
come to them. The ocean
brings them the plankton
and oxygen that they
need to survive.
Back to Open
Ocean
Dolphin
Next Animal
• Dolphins are mammals. They are
usually smaller than whales.
Many dolphins have light-colored
bellies and dark-colored backs.
This offers them some protection
from predators. Dolphins are
powerful swimmers that are
found in all of the oceans.
Dolphins can be recognized from
porpoises because they have
well-defined beaklike snouts,
with 200 and 250 sharp teeth
teeth shaped like cones. They
breathe through a blowhole. They
eat an enormous amount of food
that is nearly equal to one third
of the weight.
Back to Open
Ocean
Rays
•
Rays have broad, flattened bodies
with eyes located on the upper, dark
colored surface of the body. Their
mouth and gills are located on the
lower, light colored surface of their
body. Their pectoral fins are
extremely well developed and extend
from the tail to the sides of their
head. The huge pectoral fins allow
the fish to move through the water at
a slow pace. Rays have small mouths
with rows of flat teeth that are
perfect for crushing the shells of the
mollusks and crustaceans that they
eat. Rays have small mouths
containing huge teeth. The creatures
often bury themselves in the sand
while waiting for a meal. They can
camouflage themselves by changing
colors.
Mystery:
Good! Now that
you’ve met some of
my friends, you can
help me figure out
our mystery!
Scientists have found a new animal in the ocean!
But they’re having a hard time figuring out what it
is. See if you can help! Use what you just learned
about my friends to help the scientists figure out
what the animal is.
On a sheet of paper, record your observations of
the animal. This should include color, size, shape,
and so on. Next, to help figure out what kind of
animal it is, predict what you think it might eat,
where it might live, what other type of animals
might live near it, what kinds of animals are it’s
predators, and anything else you think might be
important to figure out what this animal is! Thanks
for your help!
