Coral Reefs ruby ramirez

Coral reefs are small marine animals that live in one place their entire life.

Coral reefs are one of the world's most diverse species.

One individual coral is called a polyp.

When a polyp is formed it usually lives near the calcium carbonate.

Coral is actually a lot of polyp put together, so it makes it look like one big one as it grows.

A polyp can use its tentacles to catch its food or prey.

Thousands of polyp live together, so that can make the reefs look alike.

The reefs can grow to 0.3 to two centimeters a year, but if it is a large reef it can to ten centimeters a year.

All coral take time to grow, and a lot of the time it is one centimeter to six inches.

It can take up thousands years for a full reef can grow.

Coral reefs can live up to 25 million years old in the ocean.

They usually like to live in more tropical or subtropical water because then the coral can be in warm water.

The more bigger reefs can be found in the Pacific or Indian Ocean.

Many of the coral reefs are made of calcium carbonate skeletons.

When a reef dies, their skeletons can either stay there or it can make a new reef.

Corals are related to jellyfish because they belong to phylum coelenterata

One third of the animals that live in the ocean live near the coral reefs.

About twenty-five percent of a house of coral reefs can cover the ocean floor.

Fish are a big help to the reefs because they can eat the seaweed that is on top of the coral, to keep them alive.

Most of the time when coral are a baby they are found floating around.

The most common time the coral reefs have to worry is when the temperature rises because the carbon dioxide can kill them.

The longest coral reef in the world is called The Great Barrir Reef.

The Great Barrir Reef is located on the East coast of Australia, in the Pacific Ocean.

This reef has been growing for more than 20,000 years.

Astronauts have said that this coral reef is so big that you can said all the way in space.

Many people call The Great Barrir Reef the " Rainforest of the Sea." Everyone calls a big coral reef the rainforest of the sea.

Coral reefs can be different colors because of the pigments and zooxanthellae tissues.

The zooxanthellae can provide food, oxygen, and many others sources

Once zooxanthellae is gone the coral reefs will its color.

Coral reefs are not plants, they are animals, but they still need to use photosyentesis to stay alive.

If the coral reef is white that means there is pollution in the ocean water.

Many of the coral reefs around the world are gone because oh human activity.

There are more than 2,500 species of coral reefs.

There are three main types of coral, fringing, barrir, and coral atoll.

There are many different species of animals near the coral reefs.

In Florida there are forty-five species of stony coral, and more than 1,700 species of sponges.

Soft and stony corals are called deep-sea corals because they live in the dark-cold water.

Some coral reefs like to live in the shade because they do not want to live near algae and other reefs.

Different scientist say that there are more names for coral reefs.

Many different species of sea animals live near the coral reefs.

Many of the animals in the ocean like to use the coral reefs to go and rest

Corals reefs can help us in many different ways, they can clean up recycle carbon dioxide.

Reefs can provide food for lobster and crabs.

Coral reefs can protect us by harsh waves, storms, and weather.

Many scientist say that more than ten percent of coral reefs are gone and that in fifty years all of Earth's reefs will be gone.

Without coral reefs many animals will die out.
