Abstract
Chaenodraco wilsoni, a species of Channichthyidae, inhabits in southern ocean. The total length of complete mitochondrial genome of C. wilsoni is 17,432 bp, which encoded 37 genes. Similar to most Antarctic fishes, the ND6/tRNA (glu) translocation and an additional non-coding region linked with ND6 have also occurred in C. wilsoni. The ML tree supports that C. wilsoni has closer relationship with Chionodraco species. Our research will provide more molecular biology information about C. wilsoni and deepen the understanding of Antarctic fishes.
