Field characteristics: Platygyra corals are Hong Kong’s flagship species.

A feature not recorded anywhere else in Indo-Pacific. P. carnosus colonies are massive, reaching heights of >1 m. This species is known as a fleshy coral with short valleys. Seam-like partitions are visible where coral tissue from neighbouring valleys adjoin. Colouration varies from a distinctive red-brick, uniform brown to pale grey with mottled red/brown tissue. Upper surfaces of colonies often form rounded turrets making the colonies appearing like miniature castles.
Abundance: Common
Distribution : The main component of coral communities in the northeastern waters of Hong Kong .Geographic distribution extends to the eastern, southeastern and southern waters. Well-represented in Hoi Ha Wan and Tung Ping Chau Marine Parks , also present in Yan Chau Tong Marine Park.
