Montastrea curta

(Dana, 1846)

Colonies are spherical, columnar or flattened. Corallites are circular and widely spaced or closely compacted. The width of calices varies greatly, this variation mostly occurring between, rather than within, colonies. Long and short septa alternate. Small paliform lobes are usually developed.

Colour: Cream or orange on reef flats, often with colours concentric to the oral discs. Usually dark brown when in shaded habitats.

Habitat: Shallow environments, especially reef flats.

Abundance: Common.

Similar species: Favia stelligera , Montastrea salebrosa

Taxonomic note: Taxonomic note: This species is divisible into several smaller semi-distinct taxonomic units. Source reference: Veron (2000). Taxonomic references: Chevalier (1971), Veron, Pichon and Wijsman-Best (1977). Additional identification guides: Veron (1986), Sheppard and Sheppard (1991), Nishihira and Veron (1995).
