Maldives waters are home to wide variety of ecosystems, but it is most noted for their variety of colorful coral reefs, home to 300 species of fish. Seven species have been described as new to science, several more await description. Over 400 have been identified and catalogued and many are now held in the reference collection, including 5 species of turtles, 51 species of echinoderms, 5 species of sea grasses and 285 species of alga & sponges, crustaceans, and tunicates. The total number of coral species recorded from the Maldives to date is about 200, representing over 60 genera, 5 species of turtles, 51 species of echinoderms, 5 species of sea grasses and 285 species of alga & sponges, crustaceans, and tunicates.

These coral reefs are home to a variety of marine ecosystems that vary from planktonic organisms to sharks, crustaceans and sponges. Sponges have gained a special interest as five species have already being identified as having anti-tumor and anti-cancer properties In 1998, warming due to El Nino phenomenon killed 2/3 of the Maldives coral reefs due to bleaching. Coral reef bleaching is a “term suggested in place of "coral bleaching" because this condition is seldom limited to corals and most affected photo symbiotic hosts reside on coral reefs”. Bleaching is the loss of photo symbiotic microorganisms (dinoflagellates, red and green algae, or cyanobacteria), or the pigments of these photosymbionts, or some of both, from tissues of host cnidarians, sponges, molluscs or other photosymbiotic host animals. The name comes from the whitening of many hosts which possess few pigments of their own.
Due to the bleaching that occurred in 1998 from the El-Nino effect, much of the coral life was reduced. The marine water had been raised as much as 5 degrees, but several scientists came together to create electrified cones. Each cone was placed anywhere from 20–60 feet below the water. The electrified cone create an attraction for the larva to attach itself. In 2004 scientists witnessed corals regenerating. Corals began to eject pink-orange eggs and sperm. The growth of these corals are surprisingly five times faster than ordinary corals. One of the scientists named Azeez Hakim witnessed this extraordinary event. “Before 1998, we never thought that this reef would die. We had always taken for granted that these animals would be there, that this reef would be there forever. El Nino gave us a wake-up call that these things are not going to be there forever.” Hakim said. This is great news because without their recovery it would be difficult to maintain the balance of the environment. “They help by removing and recycling the carbon-dioxide which in excess amounts can lead to global warming. Not only this, they also act as a natural barrier against the tropical storms, floods and tsunamis. Seaweeds grow on the skeletons of dead coral”. The corals reefs are like the rainforest for marine life.
