Bayesian phylogenetic reconstruction of selected taxa within Delphinidae based on analysis of 21 partitioned mitogenome sequences under the uncorrelated lognormal relaxed clock model. Node labels indicate posterior probabilities and node bars the 95% HPD of the estimated node age. Outgroup taxa used to root the tree include L. vexillifer, I. geoffrensis, M. monoceros, and P. phocoena, and are not shown. Illustrations are provided by U. Gorter, (not to scale).
