Mitochondrial genome of Veneriserva pygoclava

The mitochondrial genome of Veneriserva pygoclava was found to span a length of 15,709 base pairs (bp) (Fig. 8). The GC content is measured at 27.4%. In our analysis, we have successfully identified a total of 13 protein-coding genes (cox1, cox2, cox3, nad1, nad2, nad3, nad4, nad4l, nad5, nad6, cytb, atp6, and atp8), accompanied by two rRNAs and a set of 22 tRNAs. The arrangement of these mitochondrial genes presents a deviation from the typical pattern observed in the majority of annelids.
