The complete mitochondrial genome of Gymnogobius heptacanthus (Perciformes, gobiidae).

Gymnogobius heptacanthus is a small intertidal species belonging to the family Gobiidae. Herein, we report the first sequencing and assembly of the complete mitochondrial genome of G. heptacanthus. The complete mitochondrial genome is 16,529 bp long and has the typical vertebrate mitochondrial gene arrangement, consisting of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a control region. Phylogenetic analysis using mitochondrial genomes of 12 species showed that G. heptacanthus is clustered with G. urotaenia and G. petschiliensis and rooted with other Gobiidae species. This mitochondrial genome provides potentially important resources for addressing taxonomic issues and studying molecular evolution.
