Morphology and molecular phylogeny of three new deep-sea species of Chrysogorgia (Cnidaria, Octocorallia) from seamounts in the tropical Western Pacific Ocean by Yu Xu, Zifeng Zhan, Kuidong Xu

“…Chrysogorgia dendritica sp. nov. and Chrysogorgia fragilis sp. nov. were collected from the Kocebu Guyot of the Magellan Seamount chain with the water depth of 1,821 m and 1,279–1,321 m, respectively, and Chrysogorgia gracilis sp. nov. was collected from a seamount adjacent to the Mariana Trench with the water depth of 298 m. They all belong to the Chrysogorgia “group A, Spiculosae” with rods distributed in body wall and tentacles, and differ from all congeners except C. abludo Pante & Watling, 2012 by having a tree-shaped colony (vs. bottlebrush-shaped, planar or biflabellate). …”
