The horn coral also has a green fluorescence [2] or a cyano red emission. [3] They can be seen at depths from 1–30 m (3–100 ft). [5] The colonies are bushy with small conical mounts called monticules that are unique because they form where the corallite walls of the adjacent polyp fuse together. The polyps that surround the base of ...

The symmetry can be distinguished by the orientation of septa in a transverse section of the coral. Rugose corals always display bilateral symmetry whereas tabulate and ...
Tabulophyllum is an extinct genus of horn coral belonging to the order Stariidae and family Kyphophyllidae. [1] Specimens have been found in Devonian beds in Australia [2] North America, [3] and most other major areas of Devonian outcrops. The genus was highly adaptable to a variety of substrates, including muddy, sandy, and firm substrates. [4]

The calyx is relatively deep and the septa runs from its ridge to the floor. The cardinal septa is not very dominant. [1] It was described by Schlotheim in the year 1820 under the name ...
