Keywords Introgression; SNPs; COI; Microbial community analysis; Conservation; MPA 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 prevalent oceanographic currents. Abstract Deep-sea North Atlantic sponge grounds are crucial components of the marine fauna providing a key role in ecosystem functioning. To properly develop effective conservation and management plans, it is crucial to understand the genetic diversity, molecular connectivity patterns and turnover at the population level of the species involved. Here we present the study of two congeneric sponges, Phakellia robusta and Phakellia hirondellei, using multiple sources of evidence. 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 ( Author Affiliation: (a) Departamento de Biodiversidad, Ecología y Evolución, Universidad Complutense de Madrid, Facultad de Ciencias, 28049, Madrid, Spain (b) Life Sciences Department, The Natural History Museum, Cromwell Road, London SW7 5BD, UK (c) Departamento de Ciencias de la Vida, EU-US Marine Biodiversity Group, Universidad de Alcalá, 28871 Alcalá de Henares, Spain (d) Instituto Español de Oceanografía, Centro Oceanográfico de Santander, Promontorio San Martín S/n, Apdo. 240, 39080, Santander, Spain (e) Instituto Español de Oceanografía.
