Metadata on additional <i>COI</i> and <i>cyt b</i> sequences.

Information on publicly available sequences used to calculate pairwise genetic distance among genera of Petromyzontidae at the cyt b and COI genes. Note that the cyt b dataset also included sequences from S2 Table. "Genus group" indicates the genus-level groupings used to generate summary information in Tables 2 and 3.
