Figure 1 . The length distribution of COI NUMTs derived from the 658 bp barcode region of COI based upon searches in 156 marine animal genomes. The dotted vertical lines indicate read length cut-offs for standard HTS platforms (i.e., 150, 300, 450, 600 bp). A few NUMTs were longer than the 658 bp query length due to their possession of an insertion. n = 389 NUMTs ≥100 bp.
