Marine ecosystem , tourism in maldives

Marine ecosystem,,,,,,
 Maldives waters ar home to many ecosystems, however ar most noted for his or her form of vibrant coral reefs, home to 1100 species of fish, five species of ocean turtles, twenty one species of whales and dolphins, 187 species of corals, four hundred species of molluscs, and eighty three species of echinoderms. several crustacean species ar there as well: one hundred twenty copepod crustacean, fifteen malacostracan crustacean in addition as over a hundred forty five crab and forty eight shrimp species.

Examples of existing fish :


 Among the numerous marine families described ar Pufferfish, Fusiliers, Jackfish, Lionfish, Oriental Sweetlips, reef sharks, Groupers, Eels, Snappers, Bannerfish, Batfish, Humphead percoidean, noticed Eagle Rays, scorpion fish, Lobsters, Nudibranches, Angelfish, scorpaenoid, Squirrelfish, squirrelfish, Glassfish, percoid fish, Unicornfish, plectognath fish, Napoleon wrasses, and Barracudas.
 These coral reefs square measure home to a spread of marine ecosystems that adjust from organism organisms to whale sharks. Sponges have gained importance as 5 species have displayed anti-tumor and anti-cancer properties.

 1998 El Niño :
 In 1998, sea-temperature warming of the maximum amount as five °C (9.00 °F) thanks to one El Niño development event caused coral bleaching, killing 2/3 of the nation's coral reefs.[60] reef bleaching could be a term advised in situ of "coral bleaching" as a result of this condition is rarely restricted to corals and most affected photosymbiotic hosts reside on coral reefs.[citation needed] Bleaching is that the loss of photosymbiotic microorganisms (dinoflagellates, red and chlorophyte, or cyanobacteria), or the pigments of those photosymbionts, or a number of each, from tissues of host cnidarians, sponges, molluscs or different photosymbiotic host animals. The name comes from the lightening of the many hosts that possess few pigments of their own.
In a trial to induce the regrowth of the reefs, scientists placed electrified cones anyplace from 20–60 feet (6.1–18 m) below the surface to supply a substrate for larval coral attachment. In 2004, scientists witnessed corals make. Corals began to eject pink-orange eggs and spermatozoan. the expansion of those electrified corals was 5 times quicker than normal corals. man of science Azeez Hakim explicit , "before 1998, we have a tendency to ne'er thought that this reef would die. we have a tendency to had forever taken with a pinch of salt that these animals would be there, that this reef would be there forever. El Niño gave North American nation a take-heed call that these items don't seem to be reaching to be there forever. Not solely this, they additionally act as a natural barrier against the tropical storms, floods and tsunamis. Seaweeds grow on the skeletons of dead coral"."[57] The corals reefs square measure just like the woodland for marine life.
