Undergraduate students in Oceanography at the Oceanographic Institute of the University of São Paulo produced posters to expose information and curiosities about marine microorganisms. The initiative Marine MicrobeID is the result of the Course "Marine Microbiology" (IOB156), coordinated by Prof. Dr. Vivian Pellizari, and a tribute to the World Microbiome Day, celebrated worldwide on June 27 (https://worldmicrobiomeday.com/).

Good diving in this microscopic and fascinating world!
