Figure 3 . Distribution of NUMTs along the mitochondrial COI gene for phyla of marine animals. ‘Other’ includes Annelida, Brachiopoda, Cephalorhyncha, Cnidaria, Ctenophora, Hemichordata, Nematoda, Nemertea, Platyhelminthes, Porifera, and Rotifera. Analysis was restricted to 85 genomes where a full-length mitochondrial COI reference sequence was available. n = 449 NUMTs ≥150 bp.
