Lajiesittely “From Veron, J.E.N. Corals of the World.”

Galaxea acrhelia
Veron, 2000

Characters: Colonies are composed of short irregular lobe-like or truncated branches. They may be several metres across, but are usually less than 0.5 metres. Corallites are tubular, thin walled with flaring rims. Small corallites branch off larger corallites. Columellae are absent. Septa are very exsert and are commonly irregular in length. The coenosteum is soft and blistery. The whole skeleton is very fragile. Tentacles are usually extended only at night.

Colour: Pale brown or grey with white branch ends.

Habitat: Usually found in reef areas with good water circulation and light availability.

Abundance: Uncommon.

Similar species: Galaxea fascicularis , Galaxea horrescens

Taxonomic note: Galaxea acrhelia combines most of the characters of the genus Galaxea and the former genus Acrhelia. The close similarity of the corallites with those of Galaxea horrescens suggest genetic mixing between these species. Source reference: Veron (2000). Taxonomic reference: Veron (2002).
