Intra- and interspecific estimates of evolutionary divergence between Scleractinia-associated <i>Zanclea</i> and other species, expressed as the pairwise distance based on 16S markers.

<p>Intragroup distances (in bold) of Scleractinia-associated <i>Zanclea</i> do not overlap with interspecific distances.</p>*<p>Only 1 sequence was available for analysis.</p><p>Numbers of base substitutions per site from averaging all sequence pairs between and within groups are shown. Standard error estimates are shown in brackets.
