A group of Gentoo penguins speeds through the icy waters of the Antarctic summer at Port Charcot. At this time of year, penguins rapidly build colonies on the Antarctic Peninsula, finding in this sheltered bay—surrounded by mountains and icebergs—an ideal refuge. Romain and his companions anchored their sailboat for three days near the colony. Every day they immersed themselves in the freezing waters to observe these incredibly curious birds, which repeatedly approached to investigate their presence. During a freediving session, a vast group of penguins suddenly passed above him, diving in unison to feed on krill. Clumsy on land, in water they transform into fast and perfectly agile swimmers. In just moments, Romain found himself surrounded by over 200 individuals, immersed in the midst of their frenzied activity.
