Abstract
The complete mitogenome the longtail butterfly ray (Gymnura poecilura) was first presented in this study. It is 17,874 bp in length, contains 37 genes with the typical gene order and transcriptional direction in vertebrates. The overall base composition is: 28.5% A, 26.5% T, 15.0% G and 30.1% C. There are 26 bp overlaps and 41 bp short intergenic spaces located in 7 and 16 gene junctions, respectively. Two start codons (ATG and GTG) and two stop codons (TAG and TAA/T) were used in protein-coding genes. The origin of L-strand replication (OL) was found between tRNA-Asn and tRNA-Cys genes. The control region has the same A and C contents (28.8%).
