Figure 5. 16S and COI TCS haplotype networks for Neopolynoe chondrocladiae (A, B) and Neopolynoe acanellae (C, D), colour-coded by sampling station (see box). Each circle represents a distinct haplotype and the size is proportional to the number of individuals. Hatch marks on branches correspond to the number of mutational steps between haplotypes. Missing inferred haplotypes are in black. See Table 2 for details about number of specimens used for each species and genetic marker.
