Genetic diversity, gene flow and hybridization in fan-shaped sponges (Phakellia spp.) in the North-East Atlantic deep sea
Highlights: • First time hybridization is detected in deep-water sponges (Phakellia) using SNPs. • Hybridization corroborated by morphological and microbial analyses. • Connectivity between shallow populations of Phakellia robusta spanning ca. 2,000 km. • Molecular connectivity explained by prevalen...

Our phylogenetic study using a fragment of COI placed these two species as sister. Haplotype network analysis using COI revealed no genetic structure for P. hirondellei in samples from the Cantabrian Sea (<100 km).

Importantly, our analysis using SNPs combining the datasets of the two species revealed the presence of potential hybrids, which was corroborated by morphological (spicule) and microbial (16S amplicon sequencing) analyses. Our data suggest that hybridization between these two species occurred at least two times in the past.
