Rice corals
are abundant throughout the Indo-Pacific and Hawaii. The skeleton is quite
porous and therefore relatively fragile but fast-growing. They are found
in a variety of habitats and especially fine plate-like growths may be found in
quiet bays. Calices are small, simple pits surrounded by rods, nodules, or
fused ridges. Identification of many species is difficult even for
experts.
All
coral skeletons illustrated are from scientific collections taken prior
to 1998.
