Bayesian phylogenetic tree based on comparisons of 873 bp of ITS 1 and ITS 2 sequences of Spongillida. Nodes are characterized by Bayesian posterior probabilities (%) followed by bootstrap percentages; a (–) indicates that a particular analysis supported the node at less than 50%, or supported an alternative phylogenetic arrangement in ML tree. Trochospongilla latouchiana (Spongillidae; GenBank EF151955) was used as the outgroup. Scale bar denotes substitutions per site.
