Fig 4
Mitochondrial haplotype network of Polydora websteri based on COI sequences. Network represents 10 haplotypes; 8 unique, 1 shared by 5 individuals and 1 shared by 12 individuals. Each perpendicular line represents one mutation step. The areas in grey represent the larval individuals, and the areas in white represent adult individuals. The areas of the circles are proportional to the number of samples of each haplotype.
