The complete mitochondrial genome was sequenced in two individuals of the Amur sculpin Cottus szanaga. The genome sequences are 16,518 bp in size, and the gene arrangement, composition, and size are very similar to the other sculpin genomes published previously. The low level of sequence divergence detected between the genome of C. szanaga and the GenBank complete mitochondrial genome of the Cherskii's sculpin Cottus czerskii (KJ956027) may likely be due to recent divergence, historical hybridization, or presence of a new unrecognized taxonomic unit close to C. szanaga but erroneously identified as C. czerskii.
