Heatmap of the mean pairwise differences between species of Caribbean octocorals, based on nucleotide (substitutions) and indel (insertions/deletions/gaps) differences of their ND6-ND3 sequences. Colours on the diagonal indicate the mean intra-species differences. Species with a dash in the diagonal were represented by only one individual and thus their intra-species differences could not be calculated.
