A team of marine biologists and oceanographers from CNRS,UPMC and the German organization GEOMAR gain revealed the importance in all the world's oceans of a group of large planktonic organisms called Rhizaria, which had previously been totally underestimated. According to their findings, or these organisms make up 33% of the total abundance of large zooplankton in the world's oceans,and account for 5% of the overall marine biomass. The study was carried out on samples collected during eleven oceanographic campaigns (2008-2013) covering the world's main oceanic regions, and included the Tara Oceans expedition. It is published on 20 April 2016 on the website of the journal Nature.
