See text Merulina is a genus of stony corals in the family Merulinidae.

Members of this genus are native to the Indo-Pacific region and their ranges extend from the Red Sea through the Indian Ocean as far as Japan and the southern central Pacific Ocean.

[2] Merulina ampliata is the type species.

[1] Colonies can be laminar, foliose, columnar or arborescent, and can adopt all of these forms in a single colony.

On laminar plates, valleys radiate from the centre, becoming contorted on branching structures.
