Cone snails are venomous predatory marine neogastropods that belong to the species-rich superfamily of the Conoidea. So far, the mitochondrial genomes of two cone snail species (Conus textile and Conus borgesi) have been described, and these feed on snails and worms, respectively. Here, we report the mitochondrial genome sequence of the fish-hunting cone snail Conus consors and describe a novel putative control region (CR) which seems to be absent in the mitochondrial DNA (mtDNA) of other cone snail species. This possible CR spans about 700 base pairs (bp) and is located between the genes encoding the transfer RNA for phenylalanine (tRNA-Phe, trnF) and cytochrome c oxidase subunit III (cox3). The novel putative CR contains several sequence motifs that suggest a role in mitochondrial replication and transcription.
圆锥蜗牛是有毒的掠食性海洋新腹足动物，属于 Conoidea 这个物种丰富的超科。迄今为止，已经描述了两种圆锥蜗牛物种（Conus textile 和 Conus borgesi）的线粒体基因组，它们分别以蜗牛和蠕虫为食。在这里，我们报告了猎鱼圆锥蜗牛 Conus consors 的线粒体基因组序列，并描述了一个新的可能的控制区（CR），它似乎不存在于其他圆锥蜗牛物种的线粒体 DNA（mtDNA）中。这个可能的 CR 跨度约 700 个碱基对（bp），位于编码苯丙氨酸转移 RNA（tRNA-Phe，trnF）和细胞色素 c 氧化酶亚基 III（cox3）的基因之间。这个新的可能的 CR 包含了几个序列基序，这些基序提示了它在线粒体复制和转录中的作用。
