Cover design: Coccolithoviruses (family Phycodnaviridae) released from the ubiquitous, chalk-covered marine alga Emiliania huxleyi. Phytoplankton are the foundation of the oceanic food chain and their viruses are an essential component of it. Despite their importance, however, these viruses remain largely uncharacterized.
