Description
Colour: uniform dull brown, grey or green.

This species has calices whose diameters vary widely between about 10-25 mm. It has thickened septa with strong spines. Superficially, A. echinata is of similar shape and size as some Favites species, particularly F. complanata or F. flexuosa, but the spines are considerably thicker and sharper than in the latter genus. In addition, the living coral has a thick layer of fleshy tissue as is typical for mussids. The living colour is usually reddish brown, sometimes with green patches. This is a common species, especially in shallow water. Its habitats include crevices on exposed reef crests, down to 45 m depth, and in turbid water. It is thus very tolerant of a wide range of environments. Corallites are cerioid or subplocoid, circular, with thick walls. When retracted, polyps have thick concentric folds. All species of this genus have large, fleshy polyps and, when contracted, they have concentric folds. They form flat, dome-shaped colonies with a coarse honey-comb pattern. The septo-costae are toothed. Colour: varies from brown to grey or green, usually green oral discs.

Hermaphroditic, sexual, broadcast spawning.
