A block of Tomme de Savoie cheese ages with a sweater of Mucor lanceolatus fungal mold. Mucor itself doesn't have a strong taste, but more flavorful bacteria can travel far and wide along its hyphae â the microscopic, branched tendrils that fungi use to bring in nutrients.

Plankton collected in the Pacific Ocean with a 0.1mm mesh net. Seen here is a mix of multicellular organisms — small zooplanktonic animals, larvae and single protists (diatoms, dinoflagellates, radiolarians) — the nearly invisible universe at the bottom of the marine food chain.
