            There are many types of Coral Reefs

Fringing reef– a reef that is directly attached to a shore or borders it
with an intervening shallow channel or lagoon.

Barrier reef– a reef separated from a mainland or island shore by a
deep lagoon

Patch reef – an isolated, often circular reef, usually within a lagoon or

Apron reef – a short reef resembling a fringing reef, but more sloped;
extending out and downward from a point or peninsular shore.

Bank reef – a linear or semi-circular shaped-outline, larger than a
patch reef.

Ribbon reef – a long, narrow, somewhat winding reef, usually
associated with an atoll lagoon.

Atoll reef – a more or less circular or continuous barrier reef extending
all the way around a lagoon without a central island.

Table reef – an isolated reef, approaching an atoll type, but without a
Southeast Asia
Pacific including Australia
Atlantic and Caribbean
  Abiotic Factors
Close to equator ,Water Temperatures
are constant, the water is low in
nutrients, the waters are shallow
*must be photic (penetrated by the sun)
  Biotic Factors
Macro & Phytoplankton .Nurseries for
  young fish Insects & Zooplankton.
  Average temperature
25-30 degrees Celsius
  Wind Patterns
Maritime Tropical
  Soil composition
Rocks,Sand, the soil is wet, dead organisms.
  Dominate geographic features
Seagrass Meadows & Mangroves
  Solar radiation
Solar radiation causes some bleaching
  Limiting Factors
Coralline Algae (when the algae dies the coral
  reefs bleach,get hard and die.)
Seagrass (Seagrass meadows are dieing fast and
  when those die the organisms living in it die
  because the seagrass was the only source of
  food they ate.)
*Cnidarians (jellyfish)
*Crustaceans (lobsters)
*Echinoderms (starfish)
*Fan worms
* Flora (certain plant life)
*Fauna (certain wildlife)
  Limiting Factors
*Coralline Algae
Without the coralline algae the coral
  wouldn’t turn colors and if the coralline
  algae die or disappear the corals bleach
  and die.
  Environmental Status
*Protect shores from the impact of waves and from
  storms. Benefits humans in the form of food and
  medicine. Provide economic benefits to local
  communities from tourism.
When deforestation happens the are no more roost
  in the water to hold the soil in place. Causing run
  off and the soil runoff cover the corals
  smothering them and eventually killing them.
  Nature Preserves
84 million acres underwater and 99,500 sq. ft. was
  saved to preserve the coral reefs. Known to be
  the largest Preserve in history.
The climate change is the biggest danger
  factor to coral reefs. When CO2 dissolves
  in seawater it makes it more acidic.
  Affecting the way in which the coral forms.
  Reefs consist of calcium carbonate,
  produced by tiny creatures called coral
  polyps. Researchers found that as the
  CO2 dissolves in the water, it increases
  the acidity level causing the coral
  formation to slow down.
  The National Coral Reef Institute
Established by Congressional mandate in
  1998. NCRI assesses, monitors, and
  restores coral reefs through basic and
  applied research through training and
  Reef Ball Foundation (1993)
Publicly supported non-profit organization
  that functions as an international
  environmental Non-governmental
  organization. The foundation uses article
  reef technology, and transplant
  technology, public education and
  community training to build, restore and
  protect coral reefs. In over 70 countries.
