A coral forest of significant density.
The Rugosa land coral represented a species of coral. It was native to the drier zones of the moon known as Rugosa.

Coral thrived at one time in the vast oceans found on Rugosa. When those oceans vanished, some coral species demonstrated the ability to persist even without water. This resilient coral presented itself in a variety of forms, exhibiting colors from blue to purple. Among the land coral types were those resembling brains, antlers, fans, and needles. The largest coral specimens rivaled the size of trees on numerous other planets, fulfilling a similar ecological role. In certain regions of Rugosa, one could discover dense coral forests. These forests served as habitats for Neebrays.
During a mission on the moon, Jedi Master Yoda, accompanied by three clone troopers, utilized one of these coral forests as cover to evade a Separatist surprise attack.
