Acropora monticulosa

(Br├╝ggemann, 1879)

May form dome-shaped colonies over 3 metres across, composed of isolated subcolonies which are shaped like upturned hands. Colonies (or subcolonies) are digitate, with thick branches tapering to a small axial corallite. Colonies exposed to strong wave action have pyramid-shaped branchlets. Radial corallites are uniform in size and usually arranged in rows.

Colour: Blue (which may photograph purple) or cream, usually with pale branch tips of contrasting colours.

Habitat: Upper reef slopes.

Abundance: Sometimes common in eastern Australia, usually uncommon elsewhere.

Similar species: Acropora globiceps , Acropora retusa

Taxonomic note: Source reference: Veron (2000). Taxonomic references: Veron and Wallace (1984), Wallace (1999). Additional identification guides: Veron (1986), Nishihira and Veron (1995).
