Description

[edit]

All members of this genus are horn-shaped solitary corals, although the exact shape can vary between species. Phaulactis is most easily identified by its large amount of septa, deep calyx and distinct internal structure with three clear areas with different properties (but these sections are not always present in younger individuals). Another common trait is clear septal ridges.[3]
