Members of this family are bushy to tree-like and can be found in calm waters exposed to strong currents (but not to strong waves).
Soft corals of this family are found everywhere, but particularly in abundance at Hin Muang and Hin Daeng and around deeper areas at Koh Haa. Sometimes known as 'tree corals'.
Soft corals of this family are soft and rubbery. A thick 'main trunk' attaches to a hard surface on one end, with many small branches on the other end.
The colony trunk does not have any polyps, with all of the polyps being clustered at the end of the branches. The polyps are usually closed during the day, giving these corals the name 'broccoli corals' because of their resemblance to the vegetable.
At night the polyps emerge, extending their tentacles to feed.
