Octillions of microbes in the seas: Ocean microbes show incredible genetic diversity
The smallest, most abundant marine microbe, Prochlorococcus, is a photosynthetic bacterial species essential to the marine ecosystem.
It's estimated that billions of the single-celled creatures live in the oceans, forming the center of the marine food web.
They occupy a range of ecological niches based on temperature, light, water chemistry and interactions with other species.
