Info
Several specimens of Hemicorallium aurantiacum were collected at Introuvable Bank, Norfolk Ridge, New Caledonia, during various expeditions at depths between 500 and 600 meters. The initial description was based on dead fragments.
Of the specimens examined, the paratype, USNM 1196454, was the most complete specimen with a hold and whose cortex had not been abraded near the hold.
The colonies of USNM 1195220 were fragments that did not have a hold, and these specimens were dichotomously and symmetrically branched.
The size of the colonies varied between 57 and 195.5 mm in height and 52 and 92 mm in width.
Note:
Regardless of the size of the colonies, the axis of all specimens was eroded by commensal polychaetes.
However, the paratype was less severely infested by commensal polychaetes.

Note
Regardless of colony size, the axis of all specimens was eroded by commensal polychaetes.
However, the paratype was less heavily infested by commensal polychaetes.
Color
When dry, the colony's crust is dark pink-orange, and the axis is paler.
Individual sclerites are transparent or light yellow when viewed under a transmitted light microscope.
The main branch is perforated by tunnels of the commensal polychaete Gorgoniapolynoe sp.
Etymology
The specific name “aurantiacum” is derived from the Latin word “aurantiacum = orange,” which describes the axis and bark color of this species.
