LAGLIDADG phylogenetic relationships. Sponge and cnidarian sequence names are in red and blue, respectively. Solid circles indicate branches with high support values (ML BP ≥ 95 and Bayesian PP = 1.0); grey circles indicate branches with moderate support values (95 > ML BP ≥ 75 and Bayesian PP ≥ 0.90). a Maximum likelihood tree. LAGLIDADG clades from introns 714, 723, 870 and 888 are indicated with red background, blue background, green background and grey background, respectively. Branches with a ML bootstrap value below 50 % were collapsed. b Bayesian relationships among intron 723 sequences. Branch colors follow the branch colors of Fig. 1. Specifically, Homoscleromorpha and Anthozoa are indicated by black branches, while Heteroscleromorpha and Verongimorpha are indicated by blue and green branches, respectively
