Phylogenetic results considering all the analyzed ribosomal datasets and methods, showing the recovery of major clades in Cnidarian systematics proposals in our topologies and literature.

Major results considering Ceriantharia’s position are shown in blue or black font. Results are presented from the static and dynamic homology strategies, considering the 18S, 16S (no Ctenophora species in analysis) and 28S datasets. Static homology strategy, ML (x4) = Maximum Likelihood results considering 4 different analytical strategies: (1) MAFFT+RAxML, (2) RNAsalsa+RAxML (with and without secondary structure info included in these analysis), (3) gap coded as binary data matrix (RNAsalsa+FastGap+RAxML), (4): (ali: RNAsalsa+aliscore+RAxML); Static homology strategy, BY (x2) = Bayes results considering 2 different analytical strategies: (1) no gap coded (RNAsalsa+MrBayes), (2) gap coded (RNAsalsa+FastGap+MrBayes); Static homology strategy, MP = maximum parsimony results considering 30 different analytical strategies, being divided as 15 analyses with different cost weight regimes (3 of them treating gaps as missing data: RNAsalsa+TNT) and other 15 similar cost weight regimes, after alignment masking with (RNAsalsa+aliscore+TNT); Dynamic Homology strategy, ML (x2) = Maximum Likelihood results considering 2 different analytical strategies: (1) SATé (CLUSTALW+RAxML) and (2) a 18S filtered datamatrix (ali: RNAsalsa+aliscore+(SATé = MAFFT+RAxML)); Dynamic Homology strategy, BY = Bayes results from a dynamic homology analysis (BAli-Phy); no_poli = basal politomy in Anthozoa related to major recovered clades (Ceriantharia, Octocorallia and “Hexacorallia). In cases of all result/s being the considered hypotheses: YES (black box); most of results of the considered hypotheses were equal or >50% of total analyses: number of positive (dark grey); most of results considered the hypotheses were <50% of total analyses: number of positive results (light grey).
