Coral bleaching is the loss of intracellular endosymbionts (Symbiodinium, also known as zooxanthellae) through either expulsion or loss of algal pigmentation.The corals that form the structure of the great reef ecosystems of tropical seas depend upon a symbiotic relationship with algae-like unicellular flagellate protozoa that are photosynthetic and live within their tissues. Zooxanthellae give coral its coloration, with the specific color depending on the particular clade. Under stress, corals may expel their zooxanthellae, which leads to a lighter or completely white appearance, hence the term “bleached”

Its range includes southern Tibet, Sikkim andAssam in India, Bhutan, the northern mountains of Burma, and in southwestern China, in the Hengduan Mountains of Sichuan and the Gongshan Mountains in Yunnan. It may also live in southwest Tibet and northern Arunachal Pradesh, but this has not been documented.
