摘要: The complete mitochondrial genome DNA sequence of Cryodraco antarcticus was 17,857 bp in size. It consists of 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs, and one control region. Among 22 tRNA genes, 8 tRNAs were encoded on the L-strand. The overall base composition of the genome is 26.45% for A, 25.96% for T, 29.78% for C, and 17.81% for G. The phylogenetic tree suggested C. antarcticus was genetically closest to some species in family Channichthyidae. This study could provide valuable information for further studies on population structure, conservation genetics and molecular evolution of C. antarcticus.
