Montipora incrassata

(Dana, 1846)

Colonies are thick plates with or without contorted nodular columns or branches. Corallites are immersed or exsert, cup-shaped, tubular, or ‘nariform’ (where openings on the sides of tuberculae give them the shape of a roman nose, as with corallites of nariform Acropora). Tuberculae may also be fused into smooth ridges.

Colour: Mottled or uniform purple or brown, usually with white polyps.

Habitat: Mostly upper reef slopes.

Abundance: Uncommon.

Similar species: Montipora spongiosa

Taxonomic note: Source reference: Veron (2000). Taxonomic reference: Veron and Wallace (1984). Additional identification guides: Veron (1986), Nishihira and Veron (1995).
