In addition to stony corals, there are soft corals, gorgonians, black corals, sea pens and so on in Hong Kong waters. However, little is known about them, except the followings:

  • There are 26 species of gorgonians from 15 genera in Hong Kong waters. Gorgonians prevail in the eastern waters of less variable salinity. They require a firm substratum for anchorage and reach maximum abundance at about 20-25m deep.
  • Eight species of black corals from 2 genera have been recorded in Hong Kong waters. Most of them found in north-eastern waters at depth of 10-20m.
