() is a demersal and carnivorous fish species belongs to the family Congridae. Some wild populations of are in danger because of the overfishing and environmental pollution. In order to better understand the germplasm resources, the complete mitochondrial genome of was firstly determined in this study. The complete mitochondrial genome is 16,404 nucleotides, comprising 12 protein-coding genes, 2 ribosomal RNA genes, 20 tRNA genes, and 2 main non-coding regions, but ND6 and two tRNA genes were not found in the mitogenome. The mitogenome was currently the first member of genus with gene and tRNA deletion. In addition, phylogenetic analysis result demonstrated that and were clustered in a clade and formed a sister relationship.
（）是一种属于康吉鳗科的底栖肉食性鱼类。由于过度捕捞和环境污染，该物种的一些野生种群处于濒危状态。为了更好地了解其种质资源，本研究首次测定了（）的完整线粒体基因组。完整的线粒体基因组为16404个核苷酸，包括12个蛋白质编码基因、2个核糖体RNA基因、20个tRNA基因和2个主要非编码区，但在（）的线粒体基因组中未发现ND6和两个tRNA基因。（）的线粒体基因组是目前该属中首个存在基因和tRNA缺失的成员。此外，系统发育分析结果表明，（）和（）聚在一个分支中并形成姐妹关系。
