In this study, the complete mitochondrial DNA sequence of a hagfish sp. Nan-Hai from a depth of 1000 m is presented. The complete sequence was determined using next-generation sequencing and long PCRs. The mitochondrial genome of sp. Nan-Hai is 17,538 bps in size and composed of 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and one control region (D-loop). The base composition of mitochondrial genome is biased toward A + T content, at 67.21%, with GC skew of -0.35 and AT skew of -0.03. A phylogenetic tree revealed that within the genus , sp. Nan-Hai is closely related to .
在本研究中，呈现了一种来自1000米深处的盲鳗属南海盲鳗（Eptatretus sp. Nan-Hai）的完整线粒体DNA序列。该完整序列通过下一代测序和长链PCR确定。南海盲鳗的线粒体基因组大小为17,538碱基对，由13个蛋白质编码基因、两个核糖体RNA基因、22个转运RNA基因和一个控制区（D环）组成。线粒体基因组的碱基组成偏向A+T含量，为67.21%，GC偏斜为-0.35，AT偏斜为-0.03。系统发育树显示，在盲鳗属内，南海盲鳗与（此处原文缺失相关物种名）密切相关。
