Siderastrea savignyana

Milne Edwards and Haime, 1850

Colonies are encrusting or are low mounds up to one metre across. Corallites are polygonal, 2-4 millimetres diameter. Septa are neatly arranged: 30-35 at the wall, fusing in neat fan-like groups so that 10-15 fuse with the columella. Walls have a fine ridge along their tops.

Colour: Pale tan or with dark centres and white corallite walls.

Habitat: Shallow reef environments or sandy lagoons. Colonies are often partly buried in sand.

Abundance: Uncommon.

Similar species: Pseudosiderastrea tayami

Taxonomic note: Source reference: Veron (2000). Taxonomic reference: Scheer and Pillai (1983). Additional identification guides: Sheppard and Sheppard (1991), Coles (1996), Carpenter et al. (1997).
