  1. Surprisingly, Corals are marine animals found across the oceans of the world.
  2. They are very similar to anemones and appear to be half-animal and half plant.
  3. There are around 70,000 species of coral found in the world.
  4. They are mostly found in the warm tropical climates of the southern hemisphere.
  5. There are broadly two sub species depending on the number of their tentacles.
  6. The species with eight tentacles are called Alcyonaria like the soft coral, sea fans and sea pens.
  7. The corals with more than 8 tentacles are called Zoantharia and are found in Coral reefs.
  8. Corals get most of their nutrients from algae and also feed on small fish and plankton with the stinging cells on their tentacles.
  9. They need sunlight to grow and are found growing in clear shallow waters (around 200ft deep).
  10. Depending on the species they may live from 3months to 30 years.
  11. The species forming extensive coral reefs live longer than the softer corals found on their own.
  12. Interestingly, The Great Barrier Reef in Australia is made of coral polyps and stretches over 1,600 miles in length!
  13. They play a vital role in maintaining the diverse marine life.
  14. They are the meeting and breeding ground for thousands of animals especially fish.
  15. They also provide great hiding space for animals from their predators.
  16. The biggest threat to corals is growing human activities and natural disasters like earthquakes and tsunamis.
