This species is currently being identified. Each polyp is smaller than 1.2cm.
Although it may appear at first as a hydroid, it is actually a soft coral, in known as an octocral because of the eight tentacles. It is found in small patches a few cm. in diameter on the rocks right off the docks at Race Rocks in 10-12 metres of water.
Dr. Anita Brinckmann Voss identified this sample and indicated that it is related to Gersemia the soft pink coral. She has seen it in samples from Race Rocks before but not in such a large colony. She also indicated that a new species has been described from the North Pacific and she will try to get us a reference to it.
Octocorals on Coarla reefs make up a large portion of the species there. The potential medicinal uses of several species of clavularia have been published. One such study on Clavularia viridis is shown below:

Abstract
Chemical investigation of the nonpolar extract of soft coral Clavularia viridis resulted in isolation of five new prostanoids, designated as claviridic acids A-E (1-5, resp.), in addition to the known clavulones I-III. Their structures were determined on the basis of spectroscopic techniques, especially HR-ESI-MS, CD, and 2D-NMR experiments. The isolated marine prostanoids exhibited potent inhibitory effect on PHA-induced proliferation of peripheral blood mononuclear cells (PBMC), as well as significant cytotoxic activity against human gastric cancer cells (AGS).
