The seashore is where the ocean meets the land. Some seashores
are jagged and rocky, while some are flat and covered with sand.
The sandy shores are called beaches. Many kinds of plants and
animals live on the seashore. The sea gull lives on the shore
and feeds in the ocean. They eat fish, insects, and the eggs of
other birds. Usually, sea gulls are gray and white in color. They
often rest by floating on the water. Sea gulls build their nests
on rocky ledges and lay from one to four eggs. Throughout the
centuries, sailors have welcomed the sight of the sea gull because
its presence meant that land wasn't far off and their long sea
journey would soon be over. OYSTERS WITH A PEARL - Submitted by
Cherilyn of the K.O.S. Loop Art: Oyster with pearl Let the kids
paint the *inside* of 2 paper plates - Add glitter if you want

Staple the plates together at one edge and VIOLA!! You have an
oyster complete with a *pearl*. SUBMARINE - Use an appliance box
to create a mini-submarine. First cut an access hole in the back
of the box. Cut portholes for viewing and cover with plastic wrap.
Draw marine animals on the outside along with plants. Hang fish
in front of the windows. Add gadgets inside the box for instrument
panels. Place the box in the housekeeping area. SEA MAMMALS -
Make a file folder game by matching mother and baby sea mammals.
Which are pups and which are called calves. (Seals, walruses and
sea lions are pups. Dolphins, whales and manatees are calves.)
I LIVE IN THE OCEAN - Discuss with your children animals that
live in the ocean and animals that do not. Then say the name of
an animal. If the animal lives in the sea have the kids make waves

Seawater Facts
·Seawater tastes and smells salty. Although seawater is
saltier in some
parts of the ocean than others, most seawater verges 3.5 percent
salt. The
salt in seawater is mostly table salt
·Seawater also contains all the minerals found on land.
·When seawater evaporates, the salt and other minerals
are left behind.
·Objects float more easily in salty seawater than in plain
water because
seawater is more dense and can support more weight.
Geology
GLOBE - Use the globe to show where the oceans are. Ask the kids
first if
there is more land or water and then show them how 2/3 of the
earth is
covered by water.
Ocean Wave Facts
·Wind causes most ocean waves. Waves are always moving.
·The water in a wave moves up and down, not forward. Only
water in a wave
that hits land moves forward.
·Waves that keep hitting a certain part of the earth can
cut away slopping
land and make cliffs. They can also break up rocks to become beaches.
·A special kind of ocean wave is set off by an earthquake
on the sea floor.
This wave is called a tsunami (sue-nah-mee). Tsunamis can travel
as fast as
600 miles per hour on the open sea. ·Eventually they slow
down, build in
height and may crash onto land. Tsunamis occur mostly in the Pacific
Ocean.
Seaweed Facts
·Any plant that grows in the sea can be called seaweed;
however, botanists
(plant experts) refer to seaweed as only brown, red and green
algae.
·Seaweed grows along the coastlines of most parts of the
world oceans, from
polar seas to tropical waters. Seaweed "beds", the places
where a lot of
seaweed grows in one spot, provide food and protection for many
animals.
·Most seaweed is edible and can be eaten raw or cooked.
·Various kinds of seaweed are found in many products, from
medicines and
make-up to soft drinks and condiments. For example, sea lettuce
is used in
soups and salads and brewed in tea. Carageenan, made from several
kinds of
seaweed, is used a thickening agent in many kinds of hand lotion,
cough
syrup, chocolate milk, too-paste, ice cream and cottage cheese.

Introduction to the Coral Reef
Around the world, in warm and shallow waters, coral reefs are
like complex
cities that support a dazzling diversity of life. The surprising
architects
of the city are little animals called coral polyps. Usually no
bigger than
peas, the coral polyps look like tiny chrysanthemums and are just
as
colorful ? a garden of yellows, pinks, purples, oranges, blues,
and greens.
The coral polyps are able to extract calcium from the seawater
around them.
They convert the calcium into limestone and form little skeleton
cups of
rock to support their soft bodies. The coral polyps live in colonies
with
each polyp cemented to its neighbor by its skeleton and an outer
skin. As
the polyps grow, they build new skeleton cups on top of the old
ones. The
limestone formations, or coral rocks, built by millions of coral
polyps are
called coral reefs.
The structures formed by the polyps may be branched, cup?shaped,
or rounded.
There are corals that look like flowers, the horns of an elk,
mushrooms or a
human brain. Each different kind of coral grows in a specific
pattern.
The Coral Polyp
A coral polyp looks like a tiny sack with tentacles around the
top. The
polyp builds a little cup of rock, called a skeleton cup, to hold
its soft
body. The polyps live close together in colonies. All the polyps
in a colony
are joined together by a common skin and by their skeleton cups.
People dredge up pieces of coral to use as a building material.
During very
low tides, coral dies when it is expose to the sun. Discards fishing
line
gets tangled in coral and breaks it. Sea stars and parrotfish
eat coral.
Sponges, worms, and clams bore holes in the coral and weaken it.
Silt form
dredging runs into the sea and smothers the coral. Divers carelessly
touch
coral. Divers collect coral. Fishermen drop anchors on the coral
reef.
Fishermen use bleach to make lobsters come out of their holes.
The Coral Reef Community
Coral reefs provide a great variety of food and habitats for other
animals.
A coral reef is one of the most densely populated areas on earth.
Scientists
estimate that 500,000 sea animals live in or around coral reefs.
For a skin
diver, a swim through a coral reef is like being in a giant aquarium.
The coral reef community includes neon?colored tropical fish,
moray eels,
sea urchins, sea anemones, soft corals, sponges, tubeworms, barracudas,
sharks, sea stars, manta rays, sea turtles, lobsters, crabs, and
shrimp. All
of the plants and animals in the community are part of a complex
and
balanced system, where each one has its special place and function.
Symbiosis: Living Together in a Special Relationship
In the densely populated coral reef, some sea animals and plants
live
together in a special way. Two different species may be closely
associated
and interdependent throughout their lives. One or both of them
is benefited
and neither is harmed. This special relationship is called symbiosis.
Symbiosis literally means "living together."
Threats to the Coral Reef
The solid appearance of reefs might lead us to think they are
permanent,
but, actually, coral reefs are fragile, carefully balanced ecosystems
that
are easily threatened. A change in the temperature or quality
of the water,
or a change in the amount of light that penetrates the water,
can kill the
coral polyps.
Some destruction of the coral reef results from natural causes,
but man
causes the greatest damage to the reef. Once a reef is damaged,
it may never
recover. The polyps grow so slowly that before they can become
established
again, other more vigorous animals and plants move in. In many
places, the
dead and dying coral reefs are covered with thick algae. Nothing
can grow
beneath it, and the once?colorful reef community becomes a dense
green
graveyard.
Coral reefs occupy a portion of the world equal to twenty?five
times the
size of the United States. The reefs harbor millions of sea animals
that
couldn't survive anywhere else. Without the reefs, the wonderful
diversity
of life that lives around them would be lost?and many other species,
which
depend on reef animals for food, would disappear, too.
Coral Facts
·Coral animals are generally found in warm and tropical
seas. They have
cylindrical bodies that are usually less than 1 inch in diameter.
Coral
animals can be a variety of colors such as tan, orange, yellow,
purple and
green.
·Each coral animal has one end that attaches itself to
a hard surface and
one end that has a mouth with tiny tentacles. The coral uses its
tentacles
to eat algae that floats by.
·Over time coral animals produce calcium carbonate (limestone)
that collects
around the lower halves of their bodies. As a group of coral animals
grow,
the limestone deposits become bigger and bigger. When coral grows
in a line
horizontal or perpendicular to the coastline, the deposits are
called a
reef. When coral grows on a sunken bank or the crater of a volcano
that has
sunk below the surface of the sea, it is called an atoll.
·The largest construction on earth, bigger than any man-made
structure, is
the Great Barrier Reef off the coast of Australia.
Whale Facts
·The largest animal that has ever lived is the blue whale.
Measuring 95 feet
long and weighing 150 tons, the blue whale is even larger than
the biggest
prehistoric dinosaurs.
·Whales are mammals, which means they are warm-blooded
and bear their young
alive. They also breathe through lungs and must hold their breath
when
underwater. When whales return to the surface after being underwater,
they
"blow" their breath out blowholes.
·Whales can be found in all oceans. Some whales live in
groups called herds,
schools or pods. A female whale is called a cow, a male whale
a bull, and a
baby whale a calf
·There are two kinds of whales - toothed and baleen. Toothed
whales, such a
sperm whales and killer whales have teeth and eat fish and squids.
Baleen
whales, such as blue whales and humpback whales, have no teeth.
They use
their specially formed mouths to strain food, primarily plankton,
out of the
water.
Facts About Killer Whales
·Killer whales, or Orcas, are not fish, but mammals. They
have lungs and
breathe air. Their young are born alive and drink milk from their
mother.
·Killer whales, sometimes called "sea wolves,"
are hunters and live in all
the world's oceans. They eat fish and squid, as well as dolphins,
porpoises,
penguins, seals, and walruses. Other than people, killer whales
have no
natural enemies.
·Fully grown Orca bulls (males) are about 30 feet (9.15
in) long and weigh
between 15,000 and 20,000 pounds (6,800?9,100 kg). Cows (females)
give birth
every few years. A newborn calf is 8 feet (2.44 in) long and weighs
about
400 pounds (180 kg).
·Black on top and white below, a killer whale has a white
patch above each
eye and a patch of gray behind its dorsal (top) fin. Its triangular
fin
keeps the whale steady and it shows above the surface when it
swims. Killer
whales can swim more than 35 miles (56.32 km) per hour.
·Killer whales travel, hunt, rest, and play in pods (groups)
of 20 or more.
They communicate by clicks and whistles and by sliding against
one another.
·A thick layer of fat, called blubber, helps keep killer
whales warm.
·Whales have good vision, but they can see very little
in the dark murky
waters of the ocean. ·Whales cannot smell, but they can
hear sounds many
miles away with their small ear slits. ·They locate objects
in the water by
listening to the echoes of sounds.
·A killer whale breathes through a blowhole on top of its
head. The hole
closes when the whale dives under water.
·By taking a deep breath, whales can stay under water for
several minutes
before coming to the surface to breathe. When a whale comes to
the surface,
it exhales or "blows" a spout of water high into the
air like a fountain.
·Whales swim and dive by using flat, powerful tails, called
flukes. Whales
move their tails up and down when they swim, not side to side
like fish.
·Sometimes whales jump out of the water. This is called
"breaching."
Scientists are not certain why whales do this.
Shark Facts
·Sharks are considered to be meat-eating fish, although
they are not really
fish but a part of the family osteochondrichthys. They are commonly
found in
warm seas.
·Sharks have no bones. Their skeletons are made of cartilage,
a tough
elastic substance. (the human ear get its support from cartilage.)
In fact,
the name osteochondrichthys means bone-cartilage-fish.
·A shark has several rows of teeth. When a tooth is broken
or warn out, a
new one grows to replace it.
·A shark's sense of hearing is well developed, and it can
see very sell in
dim light. A shark also has special sensory tubes that allow it
to detect
electrical impulses generated by moving objects.
Sea Star Facts
·Formerly known as starfish, sea stars are not fish but
are a kind of
echinoderm (a group of animals that includes the sea urchin and
sea lily).
·Sea stars can be found in all oceans.
·Most sea stars have five arms. Each arm has tube feet
with suction disks at
the ends. A sea star uses the suction disks for crawling and attaching
to
hard surfaces. If an arm is broken off, a sea star can regenerate
(grow) a
new one.
·Sea stars come in a variety of colors such as yellow,
orange, pink red and
purple.
·A sea star's mouth is located on the underside of its
body in the middle.
Sea stars feed on mussels, clams and oysters.
Sea Horse Facts
·A sea horse is a kind of fish with a head that resembles
a horse's head.
The sea horse moves through the water in an upright position.
·The average sea horse is 5" long. Although most fish
have scales, the sea
horse had armor-like bony plates on its body. It has a long tail
that it
uses to anchor itself by coiling it around rooted plants and seaweed
floating in the ocean.
·Each female sea horse lays about 200 eggs at a time. The
male keeps the
eggs in a kangaroo-like pouch until they hatch.
Octopus Facts
·An octopus has a soft body and eight arms, or tentacles.
On the under side
of each tentacle are two rows of small, round muscles that act
like suction
cups, that stick to objects and help the octopus pull itself along
and move.
·If one of the tentacles gets caught or bitten off by an
animal, like a
shark, it will grown back in a few weeks.
· These arms are webbed together by a layer of skin called
a mantle. An
octopus has neither bones nor inside shell.
·Under this layer of skin are color cells that make the
octopus look white,
grey, orange, red, or brown. Being able to change colors can help
the
octopus catch its dinner. It's bright colors attract and confuse
other sea
animals. When they swim closer to look at the octopus, he catches
the
animal for his dinner. They can change their skin color to blend
in with
their surroundings also.
·An octopus has two eyes and sees well. It has three hearts
and breathes
through gills as fish do.
·The octopus swims by drawing water into its body and expelling
it to move
itself backwards.
· When the octopus is in danger, it can squirt a cloud
of black ink and
hides the octopus from its predators. Then it swims away fast.
·The octopus is actually a very friendly and gentle creature
- despite his
scary appearances.
·He likes to live alone of under a rock on the bottom of
the sea.
·He catches his food, most often shellfish, with the suckers
on his long
arms.
·Octopus eggs are very tiny (microscopic), about the size
of a grain of
rice. Mother octopi lay about 1000 eggs at a time in a nest she
builds under
rocks.
·The female octopus is a very good mother. After laying
her eggs, she is so
busy taking care of them she does not even eat.
·When the eggs hatch, she dies. Her work is done.
·In zoos, octopus has shown itself to be very intelligent.
·The plural form of octopus is octopi - long "i"
sound.
Jellyfish Facts
·Jellyfish live in the ocean, usually along the coast.
·Jellyfish can be various, colors, including pale orange,
pink, blue or
clear. They range in diameter from a few inches to 7 feet.
·Jellyfish swim by taking water inside their bodies and
then pushing it out
to propel themselves.
·Some jellyfish catch fish to eat by stinging them with
their tentacles.
Crab Facts
·Crabs live on rocky, muddy or sandy seashores and are
found throughout the
world. They make their homes in burrows that they dig or find.
·Crabs have a flat, broad body covered by a shell, called
a carapace. Most
crabs have 10 legs, four on each side of the body and two big
claws or
pincers, in front.
·Crabs use their legs to walk sideways across rocks and
sand.
·Crabs molt every year, which means they shed their old
exoskeleton and grow
new ones.
Scuba Diver Facts
·The word scuba originated as an acronym for self-contained
under water
breathing apparatus.
·The first scuba gear was the Aqualung. It was invented
in 1943 by
Jacques-Yves Cousteau and Emil Gagnan of France.
·Scuba diving, unlike deep sea diving, requires no airlines
or hoses from
the diver to the surface. It is often called free diving.
·A scuba diver wears a tank of pressurized air. A mouthpiece
helps regulate
the air as it is breathed in and out.
·Scuba divers can dive to 130 feet below sea level.
Hermit Crab Facts
·Hermit Crabs do not have a hard outer shell or exoskeleton
like other
crabs, so they need to use a seashell of another animal that has
died to
make a home and protect himself.
·Hermit Crabs are nocturnal.
·They have a very acute sense of smell, they seem to like
strong odors
·Their eyesight is less than keen but they can spot a good
?house? shell
from a considerably distance. The eyes are on stalks and are dark
or black
in color.
·They have antennae and shorter antennules which assist
them in feeling. The
antennae are often brownish or red.
·They have two claws and eight legs. Four of the legs hold
the shell tight
on their bodies and the other four are used for walking. The claws
are used
for defense, climbing, and tearing food apart. The left claw is
significantly larger than the right claw. The claws are often
tipped with
blue or purple.
·Hermit Crabs are born in the water but live on land in
sandy or rocky
seashores. They like to dig in the sand and climb on rocks and
wood. They
also like to hide under rock and wood during the day and to escape
from
other animals that would eat them.
CLASSROOM PETS - To keep one in your classroom, fill the bottom
of an old
aquarium with sand and some small pebbles. Put several small sticks
or
branches in for them to climb on. Put a shallow dish in for water.
Use water
that has set out long enough for them additives to dissipate.
Change every
couple of days. Put in another shallow dish for food. They will
eat a
variety of food such as: bananas, apples, cornmeal, lettuce, peanut
butter
and hermit crab chow. You can also add some plant for them to
hide under;
they will on occasion eat them. They need a moist environment
so keep a
spray bottle of water handy and spray their home once a day or
when you want
to wake them up. A cover for the aquarium helps to keep in the
moisture.
They prefer a temperature between 70 and 80, they can tolerate
it a littler
warmer or cooler. Do not place them in direct sunlight or lamplight.
Be sure
to have some larger shells for them to choose from when they outgrow
their
old one.
Fish Facts
·Two-thirds of all fish live in the ocean. About 21,000
different kinds of
fish have been identified with various features and unique qualities.
All
fish have three things in common: they are vertebrates (they have
backbones); they breathe through gills; and they are cold-blooded.
Most fish
have thin, bony scales. Some fish live together in schools.
·Fish come in all colors. Many tropical fish are brightly
colored red,
yellow, blue, or purple, with polka dots and stripes.
·Fish vary in size from the ?? pygmy goby to the 60? whale
shark.
·Most fish have fins. Fins help fish swim and keep their
balance in water.
Fish move their fins with muscles.
·Fish are able to float because of a swim, or air, bladder.
A fish can
inflate or deflate this bladder as needed to swim at the depth
it wants.
