  • After a coral animal dies, its skeleton remains.
  • Communities all over the world also depend on coral reefs for food, protection, and jobs.
  • Stony corals are the most important reef builders.
  • A coral colony is made up of thousands of identical polyps.
  • The average lifespan of a colony is five years to several centuries.
  • Corals live in tropical waters throughout the world, generally close to the surface where the sun's rays can reach the algae.
  • A coral colony is made up of thousands of identical polyps.
  • The Great Barrier Reef is made up of 900 smaller reefs.
  • The largest coral reef is the Great Barrier Reef, which spans 1,600 miles off the east coast of Australia.

  • The Great Barrier Reef can be seen from outer space.
  • The Great Barrier Reef is the world's largest reef system.
  • Any reef that is called barrier reef, gets its name because its presence protects the shallow waters along the shore from the open sea.
  • Some of the coral reefs on the planet today began growing over fifty million years ago.
  • The Great Barrier Reef is roughly half the size of Texas.
  • Most corals are made up of hundreds to thousands of individual polyps.
  • The skeletal material they produce can be either internal or external.
  • Coral reefs begin to form when free-swimming larvae attach to submerged rocks or other hard surfaces along the edges of islands or continents.
  • The average lifespan of a polyp is two to hundreds of years.
  • Individual coral polyps are usually less than half an inch.
  • Stony corals grow when individual polyps lift themselves up from the base of stony cups in which they occupy.
  • When polyps are physically stressed, they contract into their calyx so that virtually no part is exposed above their skeletons.
  • Most reef-building corals contain photosynthetic algae that live in their tissues.
  • Corals have barbed, venomous tentacles they can stick out, usually at night, to grab zooplankton and small fish.
  • Coral reefs are the largest structures on Earth of biological origin.
  • Reefs are where many fish choose to spawn.
  • Many parts of a coral reef can be harvested to a make medications to treat cancer and other illnesses.
  • Coral reefs can also be started on the shells of sunken boats.
  • Wherever coral reefs grow, the sea bed is more stable.
  • Coral reefs are usually found in shallow areas at a depth of less than 150 feet.
  • Algae live inside of corals, providing them with food and helping them grow quicker.
  • The red coral, found in the Mediterranean Sea and in the coastal waters of Japan, does not lose its color when removed from water.
  • When exposed to temperature change or pollution, corals will evict their borders, which causes coral bleaching that can kill the colony.
  • Most corals require very saline water ranging from 32 to 42 parts per thousand
  • There are over 2,500 kinds of coral.
  • Coral reefs cover less than one percent of the Earth's surface.
