Characters: Colonies are submassive and meandroid, often forming thick plates. They are rarely columnar. Valleys radiate from the original point of growth and divide at regular intervals maintaining a constant width. Septo-costae of adjacent valleys are seldom joined at the top of valley walls and are evenly spaced. Orders alternate at the colony periphery and sometimes elsewhere.
Colour: Grey or pale brown.
Habitat: Most reef environments.
Abundance: Usually uncommon but conspicuous.
Taxonomic note: The validity of Meandrina braziliensis as distinct from M. meandrites may be artificial. Source reference: Veron (2000). Taxonomic references: Roos (1971), Zlatarski and Estalella (1982), Cairns (1982). Additional identification guides: Colin (1978), Humann (1993).
