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

The purpleback flying squid (<em>Sthenoteuthis oualaniensis</em>) is a pelagic squid with tremendous potential for commercial exploitation. <em>Sthenoteuthis oualaniensis</em> 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 <em>Sthenoteuthis oualaniensis.</em> 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 <em>ND5</em>, whereas the shortest <em>ATP8</em>.
