Although the two species examined here are both members of the Holaxonia-Alcyoniina clade of Alcyonacea, they are otherwise not closely related.
The failure of the phylogenetic analysis to recover mono-phyletic species may also reflect problems within the Pseu-dopterogoria and Alcyonacea in general that go beyond the scope of our study.

For example, the evolutionary success of one group of sessile invertebrates--soft corals (Cnidaria, Alcyonacea)--living in areas of high predation and competition, such as in tropical regions, has been attributed to their production of significant amounts of secondary metabolites, especially terpenes (Tursch et al., 1978; Sammarco and Coll, 1988, 1992).
Soft corals (Octocorallia: Alcyonacea) are a major benthic component of Indo-Pacific reefs in particular, and they have a high level of ecological interaction through their production of secondary metabolites (Coll, 1992).
