Notes

Often colonial, with varied branching forms and dimensions (few millimetres to few tenths of centimetres). Colouration variable. Aggregations of hydroid colonies commonly overgrow rocks and portions of dead corals. Some hydrozoans bear resemblance to octocorals, but the latter have a much more solid structure and tend to be larger. This group likely contains a variety of species that are difficult to identify from video footage; hence, no attempt was made to identify them at a lower taxonomic level. Members of the Milleporidae , Stylasteridae and Thyroscyphidae families may be more easily identifiable from video footage (see below). Commonly known as hydroids (Fig. 107).
