Dec 2019
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 flattened stem, not in the grooves. |
