hexagonal favid corals
Hard corals with large hexagonal corallites are sometimes seen on
some of our shores.
Features: Colonies seen 10-20cm,
generally boulder-shaped, but somewhat irregular and not perfectly
spherical. The corallites large (1-2cm) have shared walls and form
large irregular cells with sharp angular edges of various sizes and
shapes. The walls are thin and tall, corallites are more tubular with
a broad 'base'. The result is a rather irregular pattern of large
polygons that resembles a honey comb. The polyps are large and fleshy
with a ring of many tentacles around a large oral disk. Colony colours
seen include brown, yellow, blue and purple.
Some species of Favid corals recorded for Singapore that have these
patterns include: Favites, Goniastrea and Lepastrea
hard to distinguish them without close examination of small features
and they are grouped here by large external features for convenience
Sometime confused with Neat
hexa corals (Pseudosiderastrea tayami) which has more conical
corallites with a narrow 'base'.
Another coral with honeycomb shaped corallites is Gardineroseris
planulata of Family
