An animal

       Do you know what is coral? Some of you might already knew this but let me tell you about this fact taken from International Coral Reef Iniative. 'Coral are invertebrate animals that belong to a large group of colourful and fascinating animals called Cnidaria. Coral are important to the marine life as they provide shelters to the other organisms.

      When there is coral, the term coral reef can exist, so the coral reef whole ecosystem. In the ocean, coral reef can be seen above 50 metres depth with suitable temperature and salinity. In the ocean, coral serves as a habitat to other marine life such as fishes, giant clams, sea stars, squids and also shrimp. Without coral, these marine life are endangered because they are being protected by coral. However, even coral is an animal, they cannot feed by themselves. This is how the system works. Coral provide shelters and some of organism provide foods for coral because coral is a sessile animal. Moreover, coral also can be an indicator of pollution. If ocean is polluted and the salinity is changing, coral will be bleached. This is a sign of pollution. 

     Lets have a thought on a brilliant quote by Sheherazade Goldsmith. 'Coral reefs represent some of the worlds most spectacular beauty spot, but they are also the foundation of marine life: without them many of sea's most exquisite species will not survive'.
