Abstract
This investigation provides the first detailed description of the growth stages of two Distichopora species showing the formation of a primary cyclosystem and explaining the growth process leading from primary cyclosystem to adult pore organisation. The earliest observed stage is an oval calcareous disc from which, at a later stage, a primary cyclosystem raises up. Then, the addition of new gastropores and dactylopores leads to the pore rows typical of the genus. Using X-ray computed microtomography, we are able to visualise the dense canal network that permeates the coenosteum and envelops the gastropores and the dactylopores in all the observed growth stages. In both species, the thin canals surrounding the gastropores are responsible for the formation of the new gastropores that originate between the old ones, while the thin canals placed on the external side of the dactylopore rows produce the new dactylopores.
