A complete mitochondrial genome of the large scaled tongue sole (cynoglossus macrolepidotus) from the east China sea.

The Large-scaled tongue sole (Cynoglossus macrolepidotus, Bleeker, 1851) is an economically important fish species in China. This study presents the first complete mitochondrial genome of the Large-scaled tongue sole, with a total length of 16,647 base pairs. The genome includes 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, and two ribosomal RNA (rRNA) genes. Phylogenetic analysis reveals that C. macrolepidotus is genetically closer to Cynoglossus joyneri and Cynoglossus puncticeps than to other species within the Cynoglossus genus. This study provides valuable genetic data for future research on C. macrolepidotus and contributes to phylogenetic studies within the Cynoglossidae family.
