Complete mitochondrial genome of the deep-sea asymmetrical barnacle (Cirripedia, Thoracica, Verrucumorpha).

The hitherto suborder Verrucomorpha contains asymmetrical barnacles of two groups: the true Verrucomorpha ( + Verrucidae) and the Neoverrucidae. Here, we determined the mitochondrial genome (mitogenome) of , a true Verrucomorpha species. The mitogenome was 15,976 base pairs in length and had the typical pancrustacean gene arrangement. Its protein-coding genes were very similar to those of other thoracican species in terms of length, AT content, and start and stop codons. In phylogenetic trees constructed with 13 protein-coding genes, . was positioned at an ancestral node of sessile barnacles, consistent with the findings of previous studies.
