Baby harp seal pups are born into a cold, windy, icy seascape. For the first 12 to 15 days of life, they rely entirely on their mothers, who nurse them with rich, fatty milk that can double their weight in days. But once those short weeks are over, the pups must face the harsh elements alone. In this fragile window, life is raw, unforgiving, and somehow all the more beautiful for being so.
