Plumapathes pennacea is a species of black coral in the order Antipatharia.

It is found in the tropical Indian, Pacific and Atlantic Oceans in deep reef habitats where it forms part of a biologically diverse community.

This colonial coral has a bushy, two dimensional form and grows out of a holdfast firmly anchored to a rock.

The slender branches fork at intervals and divide pinnately, and the smallest pinnules are a few centimetres long and close together, forming a feather-like effect.

[3][4] Plumapathes pennacea is found in tropical parts of the Indian, Pacific and Atlantic Oceans; it occurs as deep as 330 m (1,100 ft) but is most common between 25 and 60 m (80 and 200 ft),[4] and even shallower than this in caves and under dark overhangs.
