Map of the mitochondrial genome of O. lunifer. Genes coded in the α strand (clockwise orientation) are blue or cyan colored. Genes coded in the β strand (anti-clockwise orientation) are red or orange colored. Alternation of colors was applied for clarity. Start, first position along α strand; end, last position along α strand; size, size of the sequence; inc, intergenic nucleotides; fcd, first codon; scd, stop codon. Incomplete stop codons are presented with parentheses. Negative inc values refer to overlapping nucleotides for genes located in the same or different strands. Gene names are the standard abbreviations used in this paper; tRNA genes are indicated by the single letter IUPAC-IUB abbreviation for their corresponding amino acid in the draw. s1–s7, intergenic spacers.
