If I were to look at photographs of the deep structure of this piece, I'd see down into the level of the skeleton of each coral polyp, the corallite. |
The major septa of most species almost reach to the corallite axis, leaving a variably wide axial space free. |
The corallite is composed of carbonate of lime secreted by the polyp, and, broadly speaking, may be called a skeleton. |
The home of each animal is called a corallite, and the aggregation of many corallites is a corallum. |
Variations of those characters are partly due to stressed environments, such as unstable, muddy substrates resulting in corallite rejuvenescence and redirection. |
Based on corallite configuration, growth form and analogy with Acropora, Blastozopsammia had a relatively high degree of colony integration and may have been zooxanthellate. |
