Coral Reefs Devin Brooks

Coral reefs are the most diverse of all marine ecosystems

The largest coral reef in the world is The Great Barrier Reef off the coast of Australia

The Great Barrier Reef covers 2600 miles

The Great Barrier Reef is between five and 10000 years old

Reefs in the Florida Keys hold at least forty-five species of stony coral

There are thirty-seven species of octocorallia

There are five species of sea turtles

There are 500 species of fish

There are 1700 species of mollusks

There are hundreds sponges

Coral reefs need sunlight to grow

The ideal temperature for a coral reefs is between sixty-eight and eighty-two degrees Fahrenheit

They hardly grow in waters deeper than forty-five feet

91.9 percent of the worlds coral reefs are found in the indo specific region

Coral reefs are found in more than 100 countries

They are located in tropical oceans near the equator

They produce food for other marine life

Coral reefs support the fish population

Climate change increases water temperature that leads to bleaching

Coral reefs are home to of all marine life

Coral reef organisms are used for treatments for diseases

Coral reefs provide an important barrier against storms,hurricanes,and typhoons

They can be found in a place you wouldn´t expect

There are many things that can destroy their habitat like overfishing

Corals can´t survive from climate change

The value of coral reef is about thirty billion US dollars

Stony corals are the most important reef builders

The largest polyps are found in mushroom corals

Corals can be found in both shallow and deep water

High water temperature causes corals to lose the microscopic algae

Corals are small marine animals that remain in one place their their adult life

They produce a hard skeleton made from limestone

The skeleton remains when the coral animal dies

Corals grow in many different colonies and grow year after year

Skeletal material can be internal or external

Corals are anthozoans which are the largest organisms within the phylum cnidaria

All coral polyps share two basic structural features which are gastrovascular cavity and a circle of tentacles

Zooxanthellae often are critical elements in the continuing health of reef-building corals

Skeletons of stony coral are secreted by the lower portion of polyp

Massive corals grow from 0.5 centimeters to two centimeters

Number of species of corals on a reef decline rapidly in deep water

They provide protection and shelter for many species of fish and sea life

They protect coasts from strong waves and currents

It is nature's water filtration system

It controls how much carbon dioxide is in the ocean water

It's the most important food source for humans

Corals protect the world's most beautiful beaches

The adult coral is called polyp

In sexual reproduction eggs are fertilized by sperm

Atolls are usually circular or oval shaped

They are ancient animals related to jellyfish and anemones

Atoll is a ring shaped coral reef or island

The Great Barrier Reef is made up of 900 smaller reefs

Reefs cannot exist in murky or polluted water
