Geographical sampling locations of sponge host <i>H. perlevis</i> and phylogenetic network inferred from cytochrome oxidase I (COI), ATP synthase subunit 6 (ATP6) and spacer region (SP1).

<p>(A) Map indicating the specimen collection sites along the intertidal region of Atlantic coast of Portugal. (B) Pie chart represents frequency of haplotypes in each location with respective shading to the haplotypes. (C) The lower panel, networks from respective gene marker. Size of the circle is proportionate to the number of samples. The color for the circle is placed according to the haplotypes and the bold circles indicate the presence of haplotypes in more than one location. The black dots in the network indicate the number of mutation steps.
