Arrangement of the mitochondrial genome of Dugesia ancoraria. Outer circle: annotation of genes, with protein-coding genes, ribosomal RNAs and transfer RNAs represented by cyan, orange, and red, respectively. Intermediate circle: sequencing coverage, with green colour indicating coverage greater than 95% average coverage. Inner circle, with the blue colour indicating GC content and the thin orange circle indicating 50% of GC content. The picture in the middle represents an individual of D. ancoraria.
