Favia laxa   (Klunzinger)  1879 (Hard Coral)
Organism information awaits expert curation
Taxonomy
Kingdom:Animalia
Phylum:Cnidaria
Class: Hexacorallia
Order:Scleractinia
Family:Fungiidae

Description
Color: Usually pale brown or pinkish-brown.

Colonies are hemispherical. Paliform lobes form a neat crown. Septa are fine and neatly arranged. This forms massive spherical colonies up to 50 cm diameter. It has fairly variable characters. Corallites are 6 to 8 mm diameter, though with their thick walls the calices are only 3 to 5 mm across. Thus it is a small Favia; its calices are larger than Favia stelligera but otherwise only some small Favia pallida have calices this size. Corallites may be low cones, but many colonies have "recessed" rather than plocoid corallites, with no raised rim at all. There is usually a broad inter-corallite area. There is a very clear ring of tall paliform lobes around the columella.

Sexual, broadcast spawning.
