Host-microbe interactions play crucial roles in marine ecosystems. However, we still have very little understanding of the mechanisms that govern these relationships, the evolutionary processes that shape them, and their ecological consequences. The holobiont concept is a renewed paradigm in biology that can help to describe and understand these complex systems. It posits that a host and its associated microbiota withwhichitinteracts,formaholobiont,andhavetobestudiedtogetherasacoherent biological and functional unit to understand its biology, ecology, and evolution. Here wediscusscriticalconceptsandopportunitiesinmarineholobiontresearchandidentify key challenges in the field. We highlight the potential economic, sociological, and environmental impacts of the holobiont concept in marine biological, evolutionary, and environmental sciences. Given the connectivity and the unexplored biodiversity specifictomarineecosystems,adeeperunderstandingofsuchcomplexsystemsrequires further technological and conceptual advances, e.g., the development of controlled experimental model systems for holobionts from all major lineages and the modeling of(info)chemical-mediatedinteractionsbetweenorganisms.Hereweproposethatone significantchallengeistobridgecross-disciplinaryresearchontractablemodelsystems inordertoaddresskeyecologicalandevolutionaryquestions.Thisfirststepiscrucialto decipherthemaindriversofthedynamicsandevolutionofholobiontsandtoaccount fortheholobiontconceptinappliedareas,suchastheconservation,management,and exploitation of marine ecosystems and resources, where practical solutions to predict and mitigate the impact of human activities are more important than ever.
