We present the first mitochondrial genome of a South African endemic catshark, . The complete mitogenome is 16,686 bp in length, comprising 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and one non-coding control region. Similar to other shark mitogenomes, it is AT rich (61.1%), with a GC content of 38.9%. Protein-coding genes used one of two start codons (ATG and GTG) and one stop codon (TAA/TA-/T-). Phylogenetic analysis of the leopard catshark and 34 carcharhinid species showed that it clusters with two other scyliorhinid species ( and ) with 100% support.
我们展示了南非特有猫鲨的首个线粒体基因组。完整的线粒体基因组长度为16,686碱基对，包括13个蛋白质编码基因、2个rRNA基因、22个tRNA基因和一个非编码控制区。与其他鲨鱼线粒体基因组相似，它富含AT（61.1%），GC含量为38.9%。蛋白质编码基因使用两种起始密码子之一（ATG和GTG）和一种终止密码子（TAA/TA-/T-）。对豹纹猫鲨和34种真鲨科物种的系统发育分析表明，它与另外两种猫鲨科物种（和）聚类，支持率为100%。
