Mitochondrial phylogenomics and gene orders: (a) Bayesian phylogram inferred using amino acid sequences of all mitochondrial PCGs (left) and gene orders (right). Three isopod outgroups are not shown. GenBank accession numbers are included as suffix next to the species names; (b) gene orders of mitochondrial genomes in three genera of crangonyctid amphipods, including Stygobromus, Bactrurus, and Crangonyx. Conserved gene clusters are indicated by different colors and gene rearrangements are highlighted by red border lines
