Figure 2

Evolutionary networks depicting relationships among Cyt b haplotypes recovered from T. japonicus and T. nanhaiensis.
Geographic information for haplotypes is distinguished using white (East China Sea) and black (South China Sea). The sizes of circles are proportional to the frequency at which specific haplotypes were recovered. Numbers indicate mutational differences of two or more substitutions. For each network, red dots represent unsampled (missing) haplotypes.
