Corallites may be packed close together so as to be polygonal in section, with communication through mural pores; separate in clusters with either skeletal elements, coenenchyme, between, or with spaces left empty, communication through horizonatal tubes; or in contiguous chain-like rows. Coralla (pl of Corallum) may reach dimensions of 2m or more with individual corallites having diameters ranging form about 0.2 mm to 20 mm.

==Growth==
 +
Growth occurred when a polyp moved slightly upward, secreted new skeleton and settled back down on its new tabulum. It seems from the nature of coralla that growth must have been fairly simultaneous among polyps of the same colony.

In some, new corallites formed simply by the older one splitting into two.  In others new corallites branched off from the sides of older ones, which retained their presence.
