Phylogenetic tree reconstructed based on cox 1 coding sequence. Bayesian tree reconstructed from the cox 1 sequences of tetillids and an outgroup (astrophorid sponges). Introns are indicated next to the sequences possessing them. Posterior probabilities/ML bootstrap supports are indicated at the base of each branch. Accession numbers are indicated prior to the name of the taxon.
