摘要

The horned turban snail (Turbo cornutus) is an ecologically and economically important herbivorous gastropod inhabiting nearshore rocky reef habitats. T. cornutus represents a valuable coastal fishery resource in East Asia. Here, we present a chromosome-level genome assembly for T. cornutus generated using a combination of PacBio HiFi long-read and Illumina short-read sequencing and Hi-C scaffolding. The assembled genome spanned 1.93 Gb and was organized into 18 pseudo-chromosomes, representing 99.50% of the total assembly. The contig and scaffold N50 lengths were 41.02 Mb and 104.01 Mb, respectively, with repeat sequences constituting 59.07% of the genome. A total of 28,920 protein-coding genes were predicted, and genome completeness was assessed at 99.3% using the BUSCO mollusca_odb12 dataset. This chromosome-level genome assembly provides a reference for future studies on the biology of T. cornutus, the organization of the gastropod genome, and comparative genomics.
