Complete mitochondrial genome of the mangrove whipray Himantura granulata (Myliobatiformes: Dasyatidae).

In this study, the complete mitogenome of mangrove whipray Himantura granulata was first determined. It is 17,657 bp in length and consists 22 tRNA genes, 2 rRNA genes, 13 protein-coding genes and 1 putative control region with the typical gene arrangement and transcriptional orientation in vertebrates. Two start codon patterns and two stop codon patterns were found in the protein-coding genes. The tRNA-Ser2 (GCU) could not form the typical clover-leafs structure for lacking the dihydrouridine arm. The control region is 1914 bp in length with poor G (14.9%) and high A + T (59.1%) content.
