Maximum likelihood phylogenetic tree of partial COI sequences from chimaeras and sharks, constructed using the Kimura 2-parameter model. Philippine sequences are identified by UPVMI voucher codes, with related genera color-coded. Bootstrap support values (1000 replicates) are shown at nodes, and the scale bar represents evolutionary distance in substitutions per site.
