Circular map of the complete mitochondrial genome of S. cyphotergous. Genes encoded on the H-strand and L-strand are shown inside and outside the circular map of the mitogenome. Protein-coding genes of NADH dehydrogenase were colored in green, cytochrome c oxidases were colored in yellow, and ATP synthases were colored in light green. Blue and red colour represented transfer RNA and ribosomal RNA, respectively. Control region of D-loop was colored in gray.
