  • coral is a small marine animal that stays in one place for their entire adult life.
  • they produce a hard outside skeleton that is made of limestone.
  • they are related to sea anemones.
  • coral can be different from sea anemones in their production of mineral skeleton.
  • both coral and sea anemones share the same structure which includes the polyp.
  • a single individual coral is know as a polyp.
  • thousands of polyps live together to form a coral colony.
  • the polyp is similar to a tin can, open at one end and the other end has a mouth surrounded by tentacles.
  • the tentacles have stinging cells that will let the polyp of the coral capture small organisms that come to close.
  • inside of the corals polyp is a digestive and reproduction tissues.
  • coral can come in many different shapes,sizes and colors.
  • many coral reefs look like beautiful underwater gardens.
  • zooxanthellae provides coral with most of the color in coral.
  • coral is very colorful underwater but the color will fade shortly after it is taken out of the water.
  • the brain of the coral is almost spherical that makes it look like the human brain.
  • there are many different species of stony coral, turtles, fish, mollusks, and sponges in reefs.
  • these features add incredible value as a wildlife habitat.
  • coral reefs are home to one fourth of all marine life on earth.
  • the variety of the life here rivals the amazon and new guinea.
  • all the reefs found in the world take up less that one percent of the sea floor.
  • all coral reefs in the world add up to about the size of France.
  • due to corals relationship with algae reefs mainly occur in shallow water where sunlight can reach it.
  • roughly one fourth of reefs worldwide are considered damaged and can not be repaired.
  • coral reefs have survived thousands of years with the world changing.
  • major threats for reefs are over fishing, tourist, pollution, and climate change.
  • after the coral dies its skeleton of the coral will remain.
  • coral reefs can form rocky mounds or ridges in the sea.
  • coral can also provide valuable services to humans.
  • they provide food, shoreline, protection, and medicine.
  • coral reefs are going through a time of rapid decrease in ecosystem health.
  • the decrease in ecosystem health is due to human activity.
  • scientist mainly group coral reefs into three main categories.
  • the three main categories are fringing, barrier, and atoll reefs.
  • fringing reefs grow across from a shore with no lagoon in between.
  • in fringing reefs there may be a few sandy bottoms before there is a reef.
  • a barrier reef is a linear reef that is parallel to shore but is separated by a lagoon
  • an atoll is an almost circular reef system surrounded by a larger deeper lagoon.
  • the coral reef food web is similar to the other higher diverse biological communities that is very complex.
  • the coral reef food web can be put into five trophic levels.
  • most complex webs like the coral reef consist of 3-4 trophic levels.
  • the producer trophic level consist of mainly plants, algae, and bacteria.
  • the primary consumer level consist of herbivorous that include invertebrates and fish.
  • the secondary consumer level is carnivorous that feed on other animals.
  • coral reefs are found in three of Earths oceans.
  • they can be found in tropical oceans like the Atlantic, Pacific, and the Indian oceans.
  • the need for light is due to each corals dependence upon their photosynthesis partner.
  • most photosynthesis coral needs is mostly within the uppermost 100 to 200 feet into the sea.
  • coral reefs are not randomly placed through out the ocean basins.
  • there are many factors that can determine the global distribution of reefs.
  • the global distribution of reefs are determined by the ecological requirements for that reef.
  • in past years researchers have found cold coral reefs and deep water reefs.
  • coal water coral reefs feed by capturing food particles from the surrounding water.
