| Toothed
hexagonal corals awaiting identification * Family Merulinidae updated Nov 2019 Where seen? Hard corals with small 'toothed' hexagonal corallites are sometimes seen on some of our shores. Features: Colonies seen 10-15cm, generally a smooth boulder-shape. The corallites have shared walls and form irregular hexagons. The walls are thick with rather large 'teeth' compared to the corallite size. The result is a rather irregular pattern of bumpy hexagons. Colony colours seen usually pale blue, but also brown. Some species of corals recorded for Singapore that have these patterns include: Favites 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. |
