Abstract
We determined the first complete mitochondrial genome sequence of Potamotrygon motoro from South American freshwater stingrays. The total length of P. motoro mitogenome is 17,448 bp, which consists of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and a control region, with the genome organization and gene order being identical to that of the typical vertebrate. The overall nucleotide composition is 32.3% A, 24.4% T, 30.5% C and 12.8% G. These data will provide useful molecular information for phylogenetic relationships within the family Potamotrygonidae species.
