That cute little glowing fellow up there is the Hawaiian bobtail squid (Euprymna scolopes). Mattias Ormesta, a freelance Swedish photographer, is the guy responsible for capturing that adorable expression on his face. Mattias is currently involved with the development of the imaging platform of the Tara Oceans Expedition. As co-founder of the Kahi Kai team, he is responsible for taking both macro and microscopy photos of planktonic and benthic sea creatures. Matthias is also a developmental biologist. He is currently based in Stockholm, Sweden.
