The complete mitochondrial genomes of the flapper skate and the longnose skate .

We describe the complete mitochondrial genomes of the flapper skate (Parnell 1837) and the longnose skate (Linnaeus 1758), which have been obtained by Sanger sequencing. We report the length of the sequences to be 16,906 and 16,911 bp, respectively. The length and structure of gene regions, containing 13 protein-coding regions, 22 tRNA genes, two rRNA genes, and two non-coding areas, resemble those of related skate species. Despite being considered a cryptic species with , the full mitogenomes confirm that and are more genetically similar. In comparison to other species, is missing a whole codon in its cytochrome oxidase subunit 2 gene. These mitogenomes will be a useful resource furthering investigation of the population genetic differences and evolutionary history of skate species.
