The Purple and Green Hard Coral Polyps exhibit a captivating blend of colors within the coral reef ecosystem. These stony corals belong to the class Hexacorallia and construct a protective external skeleton made of calcium carbonate. Each individual polyp resides within a cup-like structure called a calyx, which surrounds its base. The polyps extend their eight smooth tentacles, which can range from yellow to green. These hardy corals propagate with relative ease, contributing to the vibrant diversity of marine life.
