Copepod and Green Algae (IMAGE)
Caption
A millimeter-sized crustacean known as a copepod excretes partially digested paramecia and green algae living inside those paramecia. A new study shows that this partial digestion exposes the otherwise-protected algae to chloroviruses, allowing the viruses to replicate and bloom in their freshwater habitats.
