Mean length (kb±standard deviation bars) of complete mtDNAs calculated for the major metazoan groups. Hash mark indicates groups including more than 10 complete mtDNAs. The size of both circular mt chromosomes of Brachionus plicatilis (Suga et al., 2008) has been used to calculate the mean value in Rotifera.
