Transcriptome dataset of seven nerites (Clithon, Neripteron, and Nerita; Neritidae)

Neritidae is one of the most diverse families in Neritomorpha, with approximately 300 extant species inhabiting various aquatic environments worldwide. Despite their ecological importance and popularity among aquarium hobbyists, genomic resources for this family remain limited, and their taxonomy is incompletely resolved. Here, we present de novo assembled transcriptomes from seven neritid species representing three genera collected from China, including Clithon pulchellum, C. retropictum, Neripteron violaceum, N. pileolus, Nerita insculpta, N. albicilla, and N. ocellata. Assembly was performed using Trinity, resulting in average contig lengths ranging from 1,098 to 1,336 bp and transcript numbers ranging from 94,216 to 160,086. All species exhibited N50 values exceeding 2,200 bp. Benchmarking Universal Single-Copy Ortholog (BUSCO) analysis showed complete BUSCO percentages ranging from 48.7% to 71.8%. Functional annotation of transcripts for each species yielded over 18,000 BLAST hits against the UniProtKB/Swiss-Prot database, with more than 17,000 GO terms, 15,000 KEGG pathways, and 7,750 Pfam accessions. Additionally, the major mitochondrial genes (comprising all 13 protein-coding genes and 2 rRNAs) were successfully assembled, among which the COI and 16S genes were utilized for species identification verification. This study provides valuable transcriptomic resources for Neritidae research, which can be applied to investigations of biodiversity, phylogenetic relationships, comparative genomics, physiological ecology, and conservation strategies for this ecologically important gastropod family.
