Abstract
The complete mitochondrial genome of the giant electric ray is 17,081 bp long (GenBank accession KM386678) and includes 2 ribosomal RNA, 22 transfer RNA, 13 protein-coding genes, an origin of replication, 2 non-coding regions. The mitochondrial gene arrangement is similar to that found in other batoids. The control region possessed a set of tandem repeats. Start codon ATG and stop codon TAA/T were found in most protein-coding genes. The base composition of the genome is 36.2% A, 29.9% T, 21.9% C, and 11.9% G.
