Transcript

  • 1. Corals are marine invertebrates which secrets calcium carbonate to form coral reefs in which small fishes live in colonies.
  • 2. Each coral reef is made up of irregular patches of algae, sessile invertebrates bare rock, sand & CaCO3. coral reef
  • 3. There are three types of reefs; * Barrier reef. * Fringing reef. * Atoll reef.
  • 4. BARRIER REEF
  • 5. It’s the Reef separated from the mainland or island shore by a lagoon. (lagoon is a shallow body of water) THE BEST EXAMPLE IS THE GREAT BARRIER REEF OF AUSTRALIA. CORAL REEFS
  • 6. FRINGING REEF
  • 7. It’s directly attached to a shore, or borders it with an intervening shallow channel or lagoon. THE BEST EXAMPLE IS THE COAST OF EILAT.
  • 8. ATOLL REEF
  • 9. It’s more or less circular or continuous barrier reef extends all the way around a lagoon without a central island. TE BEST EXAMPLE IS THE ATOLL REEF PRESENT IN MALDIVES.
  • 10. WHY ARE THE CORALS KNOWN AS MARINE INVERTIBRETS ? Live coral are colonies of small animals embedded in calcium carbonate shells. It is a mistake to think of coral as plants or rocks. Coral heads consist of accumulations of individual animals called polyps, arranged in diverse shapes. Polyps are usually tiny, but they can range in size from a pinhead to 30 cm across.
  • 11. THE BIO-DIVERSITY
  • 12. ALGAE Reefs are chronically at risk of algal encroachment. Overfishing and excess nutrient increase the growth of algae. In surveys done around largely algae inhabit a large percentage of surveyed coral locations. Algal encroachment
  • 13. SPONGES Sponges are essential for the functioning of the coral reef's ecosystem. coral reefs produce organic material. This is filtered through sponges.
  • 14. FISH There are more than 4000 species of fish in a coral reef. Here the inhabitation is like some lottery, the first comers live in that place and defend the late comers.
  • 15. AND THERE ARE MANY OTHER MARINE MAMALS AND REPTILES LIKE MARINE SNAKE,CROCODILE,LIZARDS,TURTLES,ETC …
  • 16. Fish cleaning stations Cleaner wrasse a small fish enter into other large fishes mouth to clean it by eating the leftover food particles and germs. They even clean whatever is present on the large fishes body like how some birds do for the cows and buffalos.
