Paralithodes platypus (blue king crab) has been an economically important species in Alaska, its abundance has decreased substantially since the mid-1980s. A good knowledge of genomics is conducive to the establishments of effective management and conservation strategies of this species. In this study, the complete mitochondrial genome sequence of P. platypus was determined from whole genome Illumina sequencing data. The circular genome is 16,883 bp in length, and harbors 13 protein-coding genes, 22 tRNA genes, two rRNAs genes and one non-coding control region (D-loop). The base composition of the genome is A (36.2%), C (14.9%), G (12.0%) and T (37.0%), demonstrating an obvious bias of high AT content (73.2%). The genome composition and structure of P. platypus present almost identical to other Paralithodes species. Phylogenetic analysis suggests that P. platypus is closely related to its confamilial counterparts with strong bootstrap values than to the other taxon.
