Family Subergorgiidae
updated Mar 13

Where seen? This sea fan with flat branches is sometimes seen on some of our Northern shores on coral rubble.

Features: 10-20cm long. Colony comprises many long sturdy stems that randomly branch forming an elegant tree-like silhouette on one plane, with some branches overlapping. The stems are flattened, often with a groove along the length. Dull brown-orange, to orange or red. Relatively large white polyps emerge along two sides of the stem and not in the grooves.
