Coral Reef Kimberly Vazquez

  • The greatest threats to reefs are rising water temperatures and ocean acidification linked to rising carbon dioxide levels.
  • One- quarter of coral reefs worldwide are already considered damaged beyond repair with another 2/3 under serious threat.
  • Coral reefs need water that is between 68-82 F(20-28 C).They are located along the eastern shores of land.
  • Coral reefs have survived tens of thousands of years of natural change.
  • Reefs need calcium from the water to grow often available in shallow warm waters.
  • Coral reefs help improve the surrounding water quality.
  • MPAs protect the Great Barrier Reef and the Northwestern Hawaiian islands .
  • To protect coral reefs we can make sure there is a healthy fish community and the water around the corals is clean.
  • Some corals can live at the depth of 19,000 feet (6,000 meters), reef building corals need to live in shallow waters that are less than 3000 feet (90 meters) where light can penetrate.
  • Several different species of corals can form enormous colonies that are called coral reefs, coral islands and coral atolls.
  • Coral reefs are generally found in clear, tropical oceans.
  • Reefs are essential not only to ocean health, but also to human health well being.
  • Corals that live in colder climates where water falls below 70 F(21 C) for part of the year are solitary meaning the do not form reefs.
  • Coral colonies subject to bleaching usually die off.
  • One they are gone the coral loses the brilliant color that can be seen is the white exoskeleton (coral bleaching.)
  • Coral reefs remove and recycle carbon dioxide.
  • Marine protected areas (MPAS) are an important tool for keeping reefs healthy.
  • They help sea grass and other sea plants survive in the area.
  • Reefs develop in areas where there is a lot of wave action. The waves help to bring in food,oxygen, and nutrients to the reef.
  • Waves help sediment from falling onto the reef.
  • Villages appear where their is a coral reef because they provide lot of food sources so they will not have to go into the unprotected water .
  • The value of reefs have been estimated to be 30 billion U.S$ .172 Billion U.S$ every year for food,protection of shorelines, jobs based on tourism ,and medicine.
  • The Great Barrier Reef is the largest coral in the world it is off the coast of Australia more than 1,250 meters (2,000 kilometers) long.
  • There are three types of coral reefs: barrier reefs,fringing reefs, and atolls.
  • Fringing reefs get their name from being closer to shore.
  • Barrier reefs are further out to sea and in deeper waters.
  • Barrier reefs are found near lagoons they develop a barrier between the reef and the lagoon.
  • Atolls are usually circular or oval in shape, with an open lagoon in the center.
  • Coral reefs provide an important barrier against the storms, hurricanes, and typhoons for coastal areas
  • They are the most diverse of all marine ecosystems.
  • Coral reefs make a home of 25% of marine life on the planet.
  • The diversity of the species live in corals depending on the reef latitude and direction of the water.
  • They are ancient animals related to jellyfish and anemones.
  • 25% of marine species rely on the reef for food,shelter, and breeding.
  • Coral reefs cover 1% of the ocean floor.
  • They are the habitat for 4,000 species, 700 species of coral and thousands of other plants and animals.
  • Most of the coral reefs found today are about 5,000 and 10,000 years old.
  • They are often called ¨The rain forests of the sea¨
  • They have more diversity on plant life.
  • 1,000 are the hard hard corals that build coral reefs.
  • There are 2,500 kinds of species of coral.
  • Reefs can be started at the bottom of sunken ships.
  • Wherever reefs grow the seabed is more stable..
  • The navy will sink old ships so that reefs can grow.
  • They grow in different shapes depending on their species.
  • They are made of polyps ,they are tiny organisms that look like rocks.
  • When the polyps grow the reef grows to.
  • They are a big tourist attraction.
  • During the spawning season people like to dive directly onto the water.
  • Reefs are small marine animals that live in one place their whole lives.
  • Corals are very colorful under water. Some species fade when they die or if they are removed from the water.
  • The corals organisms are used in treatments for diseases like cancer and HIV.
  • Some coral skeletons are used by humans for bone substitute in reconstructive bone surgery.
  • Scientists have only begun to understand how reefs can contribute to medicine.
  • Reefs are made of large under water structures of the skeletons of corals. They are marine invertebrate animals.
  • Corals have many ways for reproducing they can be male ,female, or both. They can reproduce sexually and asexually.
  • Asexual reproduction is important for increasing the colony size.
  • Sexual reproduction increases the genetic diversity and starts new colonies that can be different from the parents.
  • The fastest corals grow at more than six inches (fifteen cm) every year ,but the regular speed is less than an inch every year.
