DescriptionPolyps are variable in size, up to 12 mm long and 4 mm in diameter. There are 12-16 well defined marginal teeth. Polyps arise from a stolon-like band of tissue. Tentacles number between 24-32 but 28 is typical. The tentacles are long in extension and taper evenly to their tips, each of which bears a tiny but distinct terminal knob. The disc and tentacles are colourless, sometimes freckled. The column maybe whitish, buff or pink. The species is often covered in a fine layer of sand which can cover the stolon, the lower parts of the column, and extend upwards to the marginal teeth.
