Abstract：
The giant triton snail, Charonia tritonis (Linnaeus, 1758), crucial for coral reef ecosystems as a primary predator of the crown-of-thorns sea star, is experiencing a significant decline due to overfishing for its ornamental shell, underscoring the urgent need for conservation and deeper understanding of its role within marine biodiversity. This study presents the first complete mitogenome sequence of C. tritonis. Spanning 15,346 bp, the C. tritonis mitogenome comprises 13 protein-coding genes (PCGs), 22 tRNA genes, and two rRNA genes. Phylogenetic analysis of 88 Littorinimorpha mitogenomes confirms C. tritonis and C. lampas are grouped together within the family Charoniidae as a sister group to the remaining Tonnoidea families. This research not only enhances the taxonomic classification and conservation efforts for marine gastropods but also serves as a vital reference for future evolutionary and genetic studies within the Caenogastropoda.
摘要：
巨大的特里顿蜗牛，TritonisCharonia(Linnaeus,1758),作为荆棘冠海恒星的主要捕食者，对珊瑚礁生态系统至关重要，由于其装饰性外壳的过度捕捞，强调迫切需要保护和更深入地了解其在海洋生物多样性中的作用。这项研究提出了第一个完整的丝裂原序列。跨越15,346bp，Tritonis有丝分裂基因组包含13个蛋白质编码基因（PCGs），22个tRNA基因，和两个rRNA基因.对88个Littorinimorpha有丝分裂基因组的系统发育分析证实，Tritonis和C.lampas在Charoniidae家族中归为其余Tonnoidea家族的姐妹组。这项研究不仅增强了海洋腹足类的分类学分类和保护工作，而且还为Caenogastropoda中的未来进化和遗传研究提供了重要参考。
