Characters: Colonies are submassive or laminar with free margins. They are commonly up to 0.5 metres across. Valleys are approximately 8 millimetres wide and tend to radiate and bifurcate towards the colony margins. Septa are uniformly spaced and exsert. They form a thin ridge along the walls and plunge steeply in valley centres. There are no columellae. Tentacles are extended only at night.
Colour: Distinctive uniform greenish grey-brown.
Similar Species: Meandrina meandrites. See also Oulophyllia crispa which has valleys of similar width.
Habitat: Shallow reef environments protected from strong wave action.
Abundance: Usually uncommon.
Taxonomic Note: Very distinct species.
