The full-length mitochondrial genome of the crocodile icefish, Chionobathyscus dewitti (Teleostei: Perciformes: Channichthyidae)

Abstract

The full-length mitochondrial genome of the crocodile icefish, Chionobathyscus dewitti (Teleostei: Perciformes: Channichthyidae) was analyzed by the primer walking method. The mitogenome was 17,451 bp in total length, comprising 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes. Its gene order was congruent with those of the other crocodile icefish but different with those of typical vertebrates. In the phylogenetic tree, C. dewitti showed the closest relationship to Chaenocephalus aceratus in the same family.
