The populations of native iguanas in the Caribbean Lesser Antilles are threatened by the wide occurrence and spread of non-native iguanas. Until recently, competitive hybridization was not believed to threaten the Saba Green Iguana, a subpopulation of (Linnaeus, 1758) from the island of Saba. However, the arrival of non-native iguanas has put the native population at risk, leading to a change in the conservation status of the Saba Green Iguana to Critically Endangered, according to guidelines from the International Union for the Conservation of Nature. Here, we generated the complete mitogenome of the Saba Green Iguana using Oxford Nanopore long-read technology. The mitogenome is 16,626 bp long and has 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a control region (1194 bp). Noteworthy, this is only the second published mitogenome for the species complex, despite the known high intraspecific genetic variation.
加勒比小安的列斯群岛本土鬣蜥的种群受到非本土鬣蜥广泛出现和扩散的威胁。直到最近，人们还认为竞争性杂交不会威胁到萨巴绿鬣蜥，它是来自萨巴岛的（Linnaeus，1758）的一个亚种群。然而，非本土鬣蜥的到来使本土种群面临风险，根据国际自然保护联盟的指导方针，萨巴绿鬣蜥的保护状况已变为极度濒危。在这里，我们使用牛津纳米孔长读长技术生成了萨巴绿鬣蜥的完整线粒体基因组。该线粒体基因组长度为16,626 bp，有13个蛋白质编码基因、22个tRNA基因、2个rRNA基因和一个控制区（1194 bp）。值得注意的是，尽管已知该物种复合体存在较高的种内遗传变异，但这是该物种复合体已发表的第二个线粒体基因组。
