Marine microorganisms comprise a large fraction of ocean carbon and are central players in global biogeochemical cycling. Significant gaps remain, however, in our understanding of processes that determine the fate, distribution, and community structure of microbial communities. Protists and viruses are accepted as being part of the microbial loop and a source of microbial mortality. However, pelagic tunicates (salps, doliolods, pyrosomes, and appendicularians), which are abundant in oceanic and coastal environments and consume microorganisms with higher individual grazing rates than other common grazers, remain underappreciated in their role controlling microbial communities, distributions, and flux through ecosystems. In spite of sampling …
