The mud snail Bullacta exarata , a marine economic shellfish in China. It is a simultaneous androgynous molluscan species, and characteristic of euryhaline distribution and superior growth performance. To further reveal the genetic mechanisms related to environmental adaptation and reproductive traits of B. exarata , we deciphered the genomic resources of B. exarata . This study provides a chromosome - level genome assembly for B. exarata , created by PacBio and Hi - C sequencing. The genome map comprises 18 pseudochromosomes, with a total size of 867.27 Mb, a contig N50 of 4.41 Mb, and a scaffold N50 of 46.10 Mb. A total of 22,494 protein-coding genes were identified, with 21,383 genes annotated across four public databases. Overall, this study provides a foundational resource for future molecular and genetic studies on B. exarata .
