The complete mitochondrial genome of Patagonian moray cod, Muraenolepis orangiensis Vaillant, 1888 (Gadiformes, Muraenolepididae).

The full-length mitochondrial genome of Muraenolepis orangiensis (Vaillant, 1888) was studied using PacBio platform and it is first report in a Muraenolepididae family. The circular form of mitochondria genome is 16,833 bp including 13 protein-coding genes, two rRNA, and 22 tRNA. Start codon of 13 protein-coding genes was only ATG but three types of stop codons (TAA, T(AA), and TAG) were detected. To evaluate evolutionary position of M. orangiensis, the phylogenetic tree with other 13 Antarctic fishes belonged to five families were showed that M. orangiensis is unique cluster as a Muraenolepididae family and this study would provide fundamental data to understand the evolutionary relationship of fishes founded in Antarctic area.
