In this study, the mitogenome of the blackspotted catshark was first determined. This circle molecular was rich in A (30.7%)+T (30.4%), poor in C (25.0%)+G (13.8%) and contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a longest control region (3481 bp with lots of repeated motifs) in sharks. Two start codons (ATG and GTG) and two stop codons (TAG and TAA/T) were found in the protein-coding genes. The 22 tRNA genes ranged from 66 bp (tRNA-2) to 75 bp (tRNA-1). The phylogenetic result showed that did not cluster to the two species of Scyliorhinidae ( and ).
在本研究中，首次测定了黑斑猫鲨的线粒体基因组。这个环状分子富含A（30.7%）+T（30.4%），贫于C（25.0%）+G（13.8%），并包含13个蛋白质编码基因、2个rRNA基因、22个tRNA基因以及鲨鱼中最长的控制区（3481 bp，有许多重复基序）。在蛋白质编码基因中发现了两个起始密码子（ATG和GTG）和两个终止密码子（TAG和TAA/T）。22个tRNA基因长度从66 bp（tRNA-2）到75 bp（tRNA-1）不等。系统发育结果表明，[此处原文缺失相关物种名称]没有聚类到猫鲨科的两个物种（[此处原文缺失相关物种名称]和[此处原文缺失相关物种名称]）。
