Acropora nana   (Studer,  1878) (Hard Coral)
Organism information awaits expert curation
Taxonomy
Kingdom:Animalia
Phylum:Cnidaria
Class: Anthozoa
Order:Scleractinia
Family:Acroporidae

Description
Color: Cream, blue or purple, usually with purple branch tips.

Colonies are compact clumps of long, non-tapering, straight, equidistant branchlets radiating from a solid base. Axial corallites are tubular with rounded margins. Radial corallites are long, tubular and appressed. The whole colony is delicate and branchlets readily break apart.

Hermaphroditic, broadcast spawning.

Similar species: Acropora valida can be very similar when in wave washed habitats where it is distinguished by having thicker branchlets and chunkier radial corallites; also Acropora azurea.
