The complete mitochondrial genome of the hybrid snow crab Chionoecetes opilio (♀) × C. japonicus (♂) (Crustacea: Decapoda: Majoidea) and its phylogenetic analysis [version 1; peer review: 1 approved, 1 approved with reservations]

We report the complete mitochondrial genome of a hybrid snow crab between a female Chionoecetes opilio and male C. japonicus. The circular genome was 16,065 bp in length, and consisted of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a control region. The composition and arrangement of its complete mitochondrial genome were very similar to that reported for the maternal species, C. opilio. The close genetic relationship is reflected in the phylogenetic tree and supports maternal inheritance patterns.
