Complete mitochondrial genome of the plain sculpin Myoxocephalus jaok (Cottoidei: Cottidae)

Abstract

The complete mitochondrial (mt) genome was sequenced in two specimens of the plain sculpin Myoxocephalus jaok by high-throughput sequencing technology (Ion S5 platform). The sequences were 16,653 bp in size, and the gene content, gene arrangement, and size were very similar to other sculpin mt genomes published previously. Comparison of the two M. jaok mt genomes now obtained with other complete mt genomes available in GenBank reveals an affinity to the sculpin fishes from the genus Myoxocephalus. The low level of sequence divergence (1.6%) detected between the genome of M. jaok and the GenBank complete mitochondrial genomes of Myoxocephalus polyacanthocephalus (MK621914, MK621915) may likely be due to recent divergence of the species and/or historical hybridization.
