Conopressin/conophysin phylogeny. Phylogenetic reconstruction of conopressin/conophysin using sequences from representatives across the Metazoa and putative terepressin/terephysins from Tr. anilis and Te. subulata. Tree generated under ML optimality criteria with JTT + I + G and 1,000 pseudoreplicates. Bayesian analysis with four Markov chains of 10,000,000 generations each, yielded same topology. Bootstrap values (≥70) and posterior probabilities (≥0.90) are shown below each supported node (bs|pp). Terebridae sequences are highlighted in red and clades representing major phyla are indicated by colored vertical bars and closed circles.
