favid corals Family Faviidae updated Oct 11 Where seen? These hard corals with irregular hexagonal favid corallites are commonly seen on many of our shores. Features: Colonies seen about 10-20cm, sometimes larger. The corallites have shared walls and form irregular cells of different shapes and sizes, but generally with about six sides. The result is a rather irregular pattern of hexagons. Some species
of Favid corals recorded for Singapore that have these patterns
include: Favia, Favites, Goniastrea, Platygyra
and Lepastrea. 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.
Neat hexagonal coral are NOT Favid corals and belong to Family Siderastreidae. They are boulder-shaped. Corallites with short, thin, shared walls that form neat hexagonal cells. |
