Here, we report the first complete mitochondrial genome for the smalltooth sand tiger shark, (Risso, 1810). The circular mitochondrial genome was found to be 16,682 bp in length and contains 37 genes, a control region and the replication origin of the L-strand (O). The base composition of this mitogenome is 32.6% A, 23.3% C, 12.8% G, and 31.3% T. Phylogenetic analysis of Lamniformes indicates that did not group with and so the taxonomic classification of Odontaspididae needs to be revised. This study promotes conservation genetics for this poorly studied shark species which is listed critically endangered in the Mediterranean Sea.
在此，我们报告了尖吻鲭鲨（Risso，1810）的首个完整线粒体基因组。发现该环状线粒体基因组长度为16,682 bp，包含37个基因、一个控制区和轻链（O）的复制起点。该线粒体基因组的碱基组成为32.6%的A、23.3%的C、12.8%的G和31.3%的T。鼠鲨目的系统发育分析表明，[此处原文缺失具体物种名]未与[此处原文缺失具体物种名]归为一类，因此须鲨科的分类需要修订。本研究推动了对这种研究较少的鲨鱼物种的保护遗传学研究，该物种在地中海被列为极度濒危物种。
