The full-length mitochondrial genome of the Fernholm’s hagfish, Myxine fernholmi (Myxini; Myxiniformes; Myxinidae)

Abstract

The full-length mitochondrial genome of the Fernholm’s hagfish, Myxine fernholmi (Myxini; Myxiniformes; Myxinidae) was analyzed by the primer walking method. Its mitogenome was 18,862 bp in total length and was composed of 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes. The gene content and order were congruent with those of typical vertebrates. In the phylogenetic tree, M. fernholmi showed the closest relationship to M. glutinosa in the same genus and subfamily and well separated from the other hagfish in the subfamily Eptatretinae.
