The complete mitochondrial genome of dwarf form of Sthenoteuthis oualaniensis (Cephalopoda: Ommastrephidae) from the South China Sea

The purpleback flying squid (Sthenoteuthis oualaniensis) is a pelagic squid with tremendous potential for commercial exploitation. Sthenoteuthis oualaniensis comprises two forms in the South China Sea, dwarf form and medium-sized form. In this study, we described the complete mitochondrial genome of dwarf form of Sthenoteuthis oualaniensis. The genome is 20320 bp in length, encoding the standard set of 13 protein-coding genes, 20 tRNA genes and 2 rRNA genes, with circular organization. The overall base composition of the whole mitochondrial genome was A (37.23%), T (32.78%), G (10.53%) and C (19.46%) with an AT bias of 70.01%. The longest protein-coding genes of these species was ND5, whereas the shortest ATP8.
