Abstract

In this study, the complete mitogenome of Charybdis bimaculata was sequenced and annotated. The mitogenome is 15,441 bp in length, containing 37 classical eukaryotic mitochondrial regions (13 typical protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes) and a non-coding control region. Most of the genes are initiated with ATA, ATG, and ATT, though GTG is also used as an initiation codon. Twelve PCGs stop with complete termination codon TAA and TAG, while Cob uses incomplete codon (T-). The phylogenetic relationships based on 13 PCGs show that C. bimaculata clusters closest to C. fariata and C. natator.
