👉 Puffinus is a genus of penguin. It includes two species, Puffinus arnoldi and Puffinus ocellatus. These are the only known penguins that live in Antarctica. They are small, with a white head and neck, black underparts, and a light yellow body. Puffin eggs are laid on rocks or ice near the sea floor. The chicks are born on land and develop naturally, without any human intervention.
