Maximum likelihood phylogenetic tree of partial COI sequences based on the Kimura 2-parameter model, showing the relationship of Urolophus sp. (UPVMI 3116 and KAUM–I. 62938) with related sequences of Urolophus spp. from BOLD and GenBank databases, with Chimaera phantasma as the outgroup. Bootstrap support values (1,000 replicates) are shown at nodes, and the scale bar represents evolutionary distance in substitutions per site.
