Deep-sea bacteria trigger settlement and metamorphosis of the mussel Mytilus coruscus larvae

Abstract Bacteria from coast seawaters are widely known to induce larval recruitment of many invertebrates. However, whether and how deep-sea bacteria, that play crucial roles in the ecological and biogeochemical cycles, promote larval recruitment remains little known. Here, the interaction between...
