Corals in the Acanthastrea genus are large polyped stony corals from the family Mussidae. Acanthastrea colonies grow in shallow reef water and typically form massive or encrusting, flat structures with corallites that are circular or angular in shape with variation in color and appearance. The coral has thick fleshy tissue with thick partitions, or septa, and have tall projecting teeth. The identification of Acanthastrea can be difficult as they often resemble other Mussidae family members such as Micromussa and Lobophyllia. They most typically have corallites measuring between 8-15 mm. This piece is a small green Acan with contrasting pink tissue.
