Fig. 3. Diadema setosum. Minimum-spanning network of COI gene haplotypes. Area of circle proportional to haplotype frequency in total sample; length of branch proportional to number of mutations (scale bar: one mutational step) except alternative links between haplotypes, where number of mutational steps is represented by a series of perpendicular dashes. A few such links between distant haplotypes were omitted for better readability. White: haplotype sampled from Group-1 D. setosum; hachured white: Group-2; black: Sub-group-3a; grey: Sub-group-3b.
