The carnivorous gastropod Rapana venosa (Valenciennes, 1846) is one of the most notorious ecological invaders worldwide. Here, we present the first high-quality chromosome-scale reference R. venosa genome obtained via PacBio sequencing, Illumina paired-end sequencing, and high-throughput chromosome conformation capture scaffolding. The assembled genome has a size of 2.30 Gb, with a scaffold N50 length of 64.63 Mb, and is anchored to 35 chromosomes. It contains 29,649 protein-coding genes, 77.22% of which were functionally annotated. Given its high heterozygosity (1.41%) and large proportion of repeat sequences (57.72%), it is one of the most complex genome assemblies. This chromosome-level genome assembly of R. venosa is an important resource for understanding molluscan evolutionary adaption and provides a genetic basis for its biological invasion control.
肉食性腹足纲动物红螺（Rapana venosa）是世界上最臭名昭著的生态入侵物种之一。在这里，我们通过 PacBio 测序、Illumina 配对末端测序和高通量染色体构象捕获支架获得了第一个高质量的染色体尺度参考红螺基因组。组装的基因组大小为 23.00 亿碱基对，支架 N50 长度为 646300000 碱基对，锚定到 35 条染色体上。它包含 29649 个蛋白质编码基因，其中 77.22%具有功能注释。鉴于其较高的杂合率（1.41%）和大量重复序列（57.72%），它是最复杂的基因组组装之一。这种红螺的染色体水平基因组组装是理解软体动物进化适应的重要资源，并为其生物入侵控制提供了遗传基础。
