									  Coral Reefs: Most
Beautiful Marine Habitat




                 By: Alex Tang
          What Are Coral Reefs?
 Coral Reefs are the “Rainforests”
    of the ocean.
   Coral community represents one
    of the most diverse ecosystems
    in the world.
   Coral Reefs are the most diverse
    and beautiful of all marine
    habitats.
   Contain plankton, sponges,
    algae, sea urchins, starfish,
    snails, and more.
   Source of food, shelter, and
    medicine.
   Protect the coast from wave
    erosion.

             How Are They Created?
 Coral reefs start out small and
    grow approximately half an
    inch a year.
   Grow best in sunny, shallow
    and clear water.
   Grow in 64-86 degrees
    Fahrenheit.
   Without human disturbance,
    they can grow to be quite big.
   The Great Barrier Reef, off
    the northeast coast of
    Australia, is 150 km wide and    http://www-ocean.tamu.edu/education/oceanworld-old/students/coral/images/atoll_2.jpg

    2000 km long.
   Three types of Coral Reefs:
    Fringing, Barrier, and Atolls
     Where Are They Found?



               http://www.solcomhouse.com/coralreef.htm
   Coral Reefs are located in tropical islands near the
    equator 150 ft. deep.
   Primarily found in two distinct regions: The Wider
    Caribbean and the Indo-Pacific.
   The diversity of coral is far greater in the Indo-Pacific
    specifically Indonesia, the Philippines, and New Papua
    Guinea.
   Coral Reefs are found in about 100 countries.
   In the US, Florida is the only state to have extensive
    shallow coral reef formations near its coasts: The Florida
    Keys Coral Reefs.
                        Human Impact
 One of the most significant threats
    is pollution.
   Land-based runoff or pollutant
    discharges can result from
    agricultural and deforestation
    activities, sewage treatment plants,
    and dredging.
   Runoff may contain sediments,
    chemicals, oil, and debris.
   There have been increasing efforts
    to protect the diversity of these
    biologically rich areas.
   Florida Keys National Marine
    Sanctuary is one prime example.

                      Corals Are Dying
 According to scientists, the
    corals are vanishing faster than
    the rainforests.
   The coral reefs provide homes
    for about a third of all fish
    species.
   Main cause is water pollution.
   The light from the sun is being
    blocked by the sediments in the
    water which is why the corals
    are dying out.
   Corals are also blown up by
    fishers using dynamite.
   Global warming can also cause
    coral bleaching which is where     http://www.nmfs.noaa.gov/habitat/ead/EADimages/acervicornisthicket.png
    they lose their algae coating
    and turn white.
        Unique Characteristics
 Living within each coral colony is a small
  plant, a single celled algae called
  zooxanthellae.
 The algae provides food to the corals
  through photosynthesis and the corals
  provide food to the algae with its waste
  products.
 This specific relationship is a symbiosis
  called mutualism.
