Pufferfish are valuable ingredients and important fishery resources in Asia. Among them, approximately 25 Takifugu species have undergone explosive speciation in the marine environments of East Asia. Specifically, T. rubripes, T. pseudommus, and T. chinensis are remarkably similar in appearance and genetics, and their classification remains controversial.Here, we provide comprehensive genetic and genomic evidence regarding their speciation and classification. A population genetic analysis of T. rubripes, T. pseudommus, and T. chinensis using mitochondrial cytochrome oxidase subunit I and cytochrome b genes, along with 15 novel tandem simple sequence repeats, revealed clustering into a single group with notably low levels of diversity (four haplotypes with diversity values ranging from 0.0000 to 0.00065) and pairwise differentiation (microsatellite-based FST values ranging from -0.0021 to 0.0075). Furthermore, the whole genome sequence of T. pseudommus was determined, and genetic variations, including single nucleotide polymorphisms, insertions, and deletions, were examined by comparing the whole genomes of T. pseudommus and the reference T. rubripes.However, this genomic analysis failed to explain the direct association with the morphological differences characterizing each species. In conclusion, our results clearly indicate that T. rubripes, T. pseudommus, and T. chinensis constitute a single species within the same genetic pool.
