Description of twenty selected coral species commonly found within Hong Kong Marine Park Areas

Dipsastraea rotumana (Gardiner, 1899)

Family: Merulinidae
Genera: Dipsastraea
Species: rotumana
Common name: Moon Coral
Field characteristics: Coral colonies are submassive to massive. Their colony shapes range from hemispherical (massive) to flattened and encrusting (submassive). Corallites are closely packed together, especially those on the top of the colony. Their shapes are irregular. Unlike other Dipsastraea species, this coral has a very ragged appearance. This is because of their spiny skeletal structures. Conspicuous spines could be seen on the corallite wall. Colonies usually have varying shades of brown and may appear mottled.
Abundance: Abundant
Distribution : This coral species was recorded in many locations, especially in the Marine Parks in the northeastern part of Hong Kong waters.
