“Under the vast deep blue ocean there lives a important colorful creature that has become a home to millions of other marine species to grow and live.”
One of the most biologically diverse ecosystem on earth is coral reefs. So what is a Coral reef?
Reef is made of animals called stony corals which made up of colonial organism called polyps. In stony corals, this polyps sits within a calyx or a cup, which excrete a skeleton of calcium-carbonate. Polyps are connected through this skeleton and form a massive reef eventually. In addition to this, corals also host type of algae called zooxanthallae and they live in a type of relationship called symbiosis which simply means organisms help each other to survive. Corals provide the protection with their tougher outer shell and in return algea provides food and corals their strking colors.
The symbiostic relationship between coral and the algea only exist as long as water temperature of the water remains neutral. If the water gets warm, zooxanthellae is removed from the coral tissue which cuases it to lose color and major source of food and its beautiful colors. Of course this does not mean the death of the coral but it takes time and require cooler water to recover.
According to the research done by scientists, if the emmisions aren’t curbes, corals may begins to dissolove and there would be dire consequence to bio diversity and the human life. Replacemet for corals won’t come quickly nor cheaply.
