Abstract Seamounts are globally distributed across the oceans and form one of major oceanic biomes. Here, we utilized combined analyses bulk metagenome virome to study viral communities in seamount sediments western Pacific Ocean. Phylogenetic protein-sharing network demonstrate extensive diversity previously unknown clades. Inference virus-host linkages uncovers interactions between viruses dominant prokaryote lineages, suggests that play significant roles carbon, sulfur, nitrogen cycling by compensating or augmenting host metabolisms. Moreover, temperate predicted be prevalent sediments, which tend carry auxiliary metabolic genes for survivability. Intriguingly, geographical features seamounts likely compromise connectivity thus contribute high divergence genetic spaces populations seamounts. Altogether, these findings provides knowledge essential understanding biogeography ecological widespread
