Scientists have found a world of biodiversity in the plankton, tiny plants assembly, viruses and embryonic fish are the favorite food of whales and also one of the largest suppliers of oxygen on the planet.

It was known that plankton was essential for the environment, because it serves as the basis of the marine food chain and provides half of the oxygen that is generated on Earth through photosynthesis.

Now scientists discovered plankton is much more complex than they had imagined, according to five studies reported in the journal Science. The studies were conducted during an expedition several years known as the Tara Oceans project. Between 2009 and 2013, international researchers traveled aboard the French schooner “Tara” and took 35,000 samples of plankton, which includes viruses, bacteria, unicellular algae and fish-larvae of all major ocean regions.
