hexagonal favid corals awaiting identification * Family Faviidae updated Nov 11 Where seen? This hard coral with irregular lumps of angular corallites is often seen on many of our Southern shores. Features: Colonies seen 10-20cm, solid, dome-shaped or encrusting. With untidy lumps or columns of angular corallites. The corallites (1-1.5cm) have shared thick walls and form irregular, wide, shallow cells of different shapes and sizes, but generally with sharp angles and about six sides. The result is a rather irregular pattern of polygons.Tentacles are seldom seen. Colours seen include brown, blue, purple and green. Sometimes, corallite centres in a contrasting colour. Some species of Favid corals recorded for Singapore that have these patterns include: Favites and Goniastrea species. It's hard to distinguish them without close examination of small features and they are grouped here by large external features for convenience of display. |
