Radial corallites are the peripheral ones arranged around the axis formed by the axial corallite of Acropora. They can form a wide variety of shapes, not just the simple cylindrial shape that axial corallites have. They are shorter than the axial corallites, from which they bud off below the extending tip of the axial corallite.[1]
