Leptoseris explanata

Yabe and Sugiyama, 1941

Colonies are composed of unifacial laminae which may be horizontal with entire or lobed margins, or contorted and partly upright. Corallites are widely spaced and outwardly inclined. Long and short septo-costae alternate strongly and form fine but conspicuous radiating striations.

Colour: Pale brown or yellow-brown, often with white margins.

Habitat: Usually found on vertical or overhung faces, especially of lower reef slopes.

Abundance: Uncommon.
